Help finding Molex 070107-a MX-2 Connector Kit.

railerswim — Wed, 01 Jul 2015 15:02:44 GMT

Hi, I'm new to the community (although I browse the more public side of the website quite often and watch the Ben Heck Show).

But I have a quick question. I work for the IT Department for a large agricultural Coop. We have a Portable Server Environment Fanmodule that has a couple dead fans. I found the fans online, they come pre-spliced but the mount's power adapter has the fans terminated to Molex MX-2 connectors. I can only find the female connector and I'm also having a hard time finding the terminals for the female ends.

Here's more details on the fans in the module.

Manufacturer - ebm-papst

Fan Size - 119mm

Voltage - 12v dc

Connector - Terminated (currently using Molex 070107-a MX-2)

Seriously any help would be appreciated. Thanks!

Edit: Never mind I found it.

Searching for the right connectors

Former Member — Tue, 05 Aug 2014 07:33:43 GMT

Hi!

for a small hobby project we need some wire-to-wire connectors which should also be able to be used as wire-to-board without changing the plug on the wire side when we switch from development to production board. Could this be done with the Molex SL series? Could someone of you give me some sets of product numbers for 2, 3 and 4 pin versions, as well as the needed crimp terminals which would work together? Maybe in a table like this:

wire side		wire/board side
wire housing	crimp terminal	wire housing	crimp terminal	PCB
0050579404	0016020105	0701070003	0016020108	0705430038

Standard tin plating for 24-30 AWG is enough. My table contains the Molex part numbers for a 4 pin setup I think should fit together and are available at Farnell at small quantities. Did I find the right parts?

Kind Regards,

Christian

Barrier terminal strip rating

Former Member — Tue, 08 May 2012 16:29:31 GMT

I want to connect four wires to a Molex barrier terminal strip, (38280-0104). The wires are 24 AWG 1000 VDC rated. The voltage being applied is 1000 VDC @ .5 Amp MAX- 500 watts. The Molex 28 Series is rated at 600 Vrms @ 50 Amp 3000 watts. Is the watt rating allow for safe connection considering the lower amperes or is the voltage rating absolute.

Pros and Cons of Eliminating Hazardous Substances

MolexConnectors — Tue, 07 Dec 2010 18:16:42 GMT

So we previously learned some of the risks of BFRs, CFRs, and PVC. What is Molex doing to mitigate these risks? First, let's take a look at the terminology used and some alternatives.

Terminology / Definitions

So we want to remove these substances that could cause harm. What do we call this trend? Well, it seems everyone has come up with their own term! Halogen-Free, Low-Halogen, and BFR/CFR/PVC-Free are common terms used. They're all a mouthful, and some don't even accurately describe the situation. Also, what's the acceptable level of these substances, knowing that unintentional impurities can exist? And what about other brominated and chlorinated substances?

To be safe, Molex has adopted a conservative definition for this trend – one that meets all of our customers' definitions. A product that has less than 900 ppm (0.09%) bromine, less than 900 ppm chlorine, and less than 1500 ppm (0.15%) of bromine and chlorine combined, meets the requirement. For now, we call these products 'Halogen-Free' or 'Low-Halogen.'

BFR/CFR Alternatives

We've decided we want to get away from brominated and chlorinated flame retardants. We'll just use another material ... easy right? Well, not exactly. Many Molex connectors use a brominated flame retardant (remember – it's used to slow down the spread of fire, so using a BFR sounds like a good idea!). There are three ways we can get away from BFRs:

Some plastics are inherently flame-retardant (in other words, a flame retardant doesn't need to be added to slow the spread of fire). Sounds like an easy choice! Except that those plastics may have completely different properties (some are very brittle and might break). And, of course, they're typically more expensive.

What about using a different kind of flame retardant? Molex has been working with its plastic suppliers, who have been developing non-brominated, non-chlorinated flame retardants. Some of these show promise and are currently being used. Again, there are differences, so each product needs to be re-evaluated.
The third option is to remove the flame retardant entirely. If the connector is used in an application where a fire isn't likely to happen, or the current is low enough, the plastic may not even need a flame retardant. Plastics already exist without flame retardants, and are used in many applications.

PVC Alternatives

We've also decided we want to replace PVC with another material – one that's just as flexible. Well, we can't have everything – the alternatives could be up to ten times as expensive! Of course, over time, prices will drop as supply catches up, but in the meantime, a premium will be paid for the substitutes. Some examples:

Polyethylene
Fluorinated polymers (FEP, ETFE, PVDF)
Ethylene propylene diene elastomer (EPDM)
Polyurethane

Molex's Activities

Molex has been working with its suppliers and customers to design new products that don't contain these substances that could pose hazards. We have experience in creating a connector that doesn't have brominated or chlorinated flame retardants, and we've worked with cables that aren't PVC. Certainly, there are challenges, and not every material can be easily replaced. In the meantime, if a Molex customer needs a product without BFRs, CFRs, and PVC, just let your account manager know – he or she will be able to work with you to meet your needs!

So what’s the big deal about halogens?

MolexConnectors — Mon, 29 Nov 2010 20:55:27 GMT

Halogen-Free. Low-Halogen. BFR-free. PVC-Free. BFR/CFR/PVC-Free. What?

The electronics industry is all abuzz about removing certain substances – that aren’t even (currently) regulated in any country! What’s the big deal? Why are we spending so much money to change products to other, more-expensive, materials, when the original materials ‘work’ just fine? Let’s first look at the concerns with these groups of substances, then talk about alternatives and what Molex is doing.

Brominated and Chlorinated Flame Retardants (BFR/CFR)

Flame retardants are used in plastics to reduce fire from spreading (bet you couldn’t figure that out from their name!). If the plastic component can’t burn well, then the fire can’t burn as quickly. If a fire starts in your home television and spreads to the rest of your home, you’ll want to get out as quickly as possible. These flame retardants in Molex connectors slow the spread of fire, potentially preventing the fire from spreading to the rest of your home, or allowing you those crucial extra moments to escape safely. So what could possibly be bad about these helpful substances?

Well, many consumer electronics have a short life-span, and none of us want electronics to end up in landfills. When electronics are recycled, the materials need to be segregated by type – this allows the materials to be recycled and reused more efficiently. Plastics go with similar plastics; metals go with similar metals. Many plastics are burned, and if this process is not performed properly, hazardous dioxins and furans could form from the brominated or chlorinated flame retardant. Get rid of the brominated or chlorinated flame retardant, and get rid of that problem, right?

Polyvinyl Chloride (PVC)

PVC is a polymer that is used primarily in cables, but also other components. Phthalates are a group of substances added to PVC to make the cables flexible. Plugging a rigid power cable from your mobile phone to the wall outlet wouldn’t work well! Flexible PVC allows the cable to bend. So what’s the big deal?

Well, disposal or burning of cables can also generate hazardous dioxins and furans. In addition, phthalates have been found to be dangerous, and some countries regulate phthalates in toys and medical devices. Replacing PVC with an alternative will remove both of these potential hazards.

What are the alternatives? What is Molex doing? We’ll discuss this in a future environmental blog post.

Are Discrete Wires Too Outdated For Handheld Devices?

MolexConnectors — Wed, 17 Nov 2010 16:56:31 GMT

Inside a tightly-packaged modern smartphone, flexible circuitry dominates the space, connecting various modules to the main logic board using microminiature board-to-board and FPC connectors. The space-saving and lightweight nature of these components for relatively high circuit size interconnects has certainly contributed toward the never-ending drive for miniaturization. Yet you still occasionally see some conventional discrete wires. Modules such as batteries, speakers and vibra motors are still sometimes connected to the main logic board by discrete wires. These modules may be attached to the chassis of the device, and the flexibility and cost-effective nature of discrete wires provides phone designers the freedom to position such modules almost anywhere.

Designers may want to distance certain components from RF modules, which could otherwise negatively impact the performance of their device. Thus, there is still a need for small, low profile wire-to-board interconnect solutions. One of the latest products from Molex, called Pico-EZmate™, is an ultra-low profile, right angle wire-to-board connector in 1.20mm pitch, but with a vertical mating direction. It has a mated height of 1.55mm, and is available in 2 through 5 circuit versions (a 6-circuit version is also available with a mated height of 1.65mm). It is halogen-free and glow-wire compliant. The vertical mating direction is design-friendly because it provides freedom to position other components around the connector on the printed circuit board, whereas conventional right angle wire-to-board connectors with a horizontal mating action typically have to be placed around the edge of the printed circuit board. Needless to say, the vertical mating direction is also operator-friendly for the final assembly operation.

Molex’s existing Pico-EZmate connector is being used in applications as diverse as smartphones, notebook PCs, tablet PCs, e-book readers, medical devices, gaming machines, barcode readers, digital cameras, navigation devices, lighting, wireless modems and many, many more. For these applications, the existing connector proved to be quite small enough. But the question now is whether customers in the future will require an even smaller version of this already small, yet manageable product. Smartphone designers are interested in further component miniaturization. But will further miniaturization be practical for their manufacturing partners, from a final assembly point of view? What is your opinion?

SFP(+) to cool or not to cool?

MolexConnectors — Wed, 22 Sep 2010 20:11:39 GMT

With SFP cages comes always the question whether cooling is necessary or not. There is no clear answer this question. Mainly because there are several parameters which have to be taken into consideration:

1. The heat dissipation of one SFP insert can go from zero (copper cable) to approx. 2 watts (when using a twin bi-directional LC insert)

2. The equipment practice may be a rack with vertical daughter cards or a pizza box with only a main board or with additional mezzanine cards on top

3. The number of ports on a daughter card/mezzanine board

4. The density of the ports, whether these are single cages with space in between, ganged cages, or stacked and ganged cages

5. The airflow in the system, which is always bottom up in a rack, but it may be different in a pizza box (East->West or Rear-Front)

6. The ambient temperature (fan supported approx. +40°C), the maximum temperature of the insert (typically +70°C) and the air flow speed

7. Last but not least the “swelter effect” e.g. the first SFPs are heating up the ones at the end of the airflow

We at Molex did a lot of simulations in our thermal labs to understand the results of the above parameters. However, still we do not have a universal recipe to have a black and white solution for the problem. A few guidelines may help.

As long as we are talking single cages with space in between, we are on the safe side if the dissipated heat is below one watt per insert. When you start ganging these cages, it is still no problem, assuming you have a copper ground plane underneath the inserts that distributes the heat away.

At the moment you are above one watt per insert, care should be taken, especially when ganged SFP cages are your free choice or forced decision. Investigating the configuration of a fully SFP-loaded front panel with inserts above 1.5 watts heat dissipation each insert, we immediately recognized we have to cool the inserts.

The first hurdle was to find a good thermal connection between the insert and the heat sink. Only QSFP inserts are designed from the beginning to have a flat and smooth surface on top to have an intimate contact to a heat sink. SFP inserts do not always have this and – even worse – some inserts have the manufacturing label on top, which is not a good heat conductor. You may improve the situation with conductive heat cushions, but the thermal contact is questionable.

: Heat Sink Cushion

The second hurdle was – under a defined insert with a defined heat cushion – to select the right heat sink in the given environment. The environment was a rack with vertical daughter cards and 24 ganged SFP ports (4 cages each 6 ports).

: SFP Thermal Test Bench

Knowing the height of only 15,2mm above the board, it was clear that a heat sink on top of the SFP cages just blocks the airflow, which is worse than using no heat sinks. The heat sinks must have fingers (no ribs) to create turbulences and get a better thermal conductivity to the air. Finally, we decided to go for “rucksack” heat sinks since a lower profile with a rucksack is more efficient than a higher heat sink just above the cages.

We tested several heat sink configurations and found the lower profile longer rucksack as the best performer. However, even with the extended rucksack we had to apply a baffle in order to squeeze the airflow onto the rucksack area, which is shown on the sketch “Rucksack with baffle”

: No Rucksack

: Rucksack short

: Rucksack extended

: Heat Sink Comparison

Last but not least, a heat sink comparison matrix was created which showed clearly:

a) Heat sinks are sometimes worse than no heat sinks

b) Without a baffle, the airflow bypasses the heat sink area and airflow is in vain

c) More baffles do not improve the cooling effect

d) Most critical is the “swelter effect” in an arrangement as simulated; the lower SFPs heat up the upper SFPs when airflow is not controlled

Molex is offering a large variation of cages for SFP, QSFP and CXP. We investigated, simulated and verified thermal issues with stacked and ganged configurations of SFP and QSFP as we foresee a wider usage of cages in the industry. Not only with heat dissipation from fiber optic transceivers, but also with dissipated heat from active copper cables where equalizers are integrated into the cable plugs.

De-Rate or not De-rate? That is the question!

MolexConnectors — Wed, 01 Sep 2010 17:39:55 GMT

De-Rate or not De-rate? That is the question! By The Molex Power Expert: Ken Stead

The practice of derating power connectors has been varied among users for decades. Back in the day, (yes, I am over 50!) many users took a simple approach, assigning an arbitrary percentage to the current carrying capability – we’ll call it the C³ or C cubed factor. So if a connector supplier submitted a product that was rated at say 100 amps, then a user would factor by say 30%. The idea was that since this is a huge safety issue, no one wanted to take any chances that a power connector may over heat. The fear was that once over heating took place, the phenomenon known as “thermal runaway” could cause catastrophic failure.

So space and cost be damned, no power engineer was going to take any chance at all – thus the derating process. Who is going to argue and take responsibility for what, in the extreme, could be a life-threatening failure? Now flash ahead to the 21st century where space and cost are king. Pressures on telecommunications and computing system makers for smaller and cheaper products have placed enormous pressure on power engineers. What once was hallowed ground is now under close scrutiny. The decision to derate a power connector is much more complicated, and often the timing to make this decision adds to the stress. Power engineers are looking at airflow, PCB copper and many other factors versus a simple percentage factor. So, how do you derate? As I like to say in Molex, if a backplane connector or an I/O malfunctions, you call a help desk for support. If a power connector fails, you may have to call 911! NOBODY wants that on their resume!
