Nooooooo... say it is not so! Shabaz my Element14 electronics superhero has found his kryptonite. What next standing in water holding AC power cords?

This tool breaches the insulation to expose the conductor to a probe. The world is full of failed good intentions. I can save you a few bucks. File the pins on the end of your voltmeter meter test probes to a fish hook point tip and then use them to jab through the insulation covering wires to make contact with the conductor to take measurements.

Now that you have become comfortable using this methodology to do testing, how about taking measurements from conductors on your boat or in your car or better yet why not through foreign electrical wires that run through your wall. Hey there are some really thick wires in pre-digital TV than can do with a ***.

Wires are coated with insulation for a reason. It insulates! Breaking down that insulation barrier at any point along the conductor can lead to problems. Just think, every time you take your car in for servicing another vehicle tech starts pricking wires. No problem there is a bundle here, poke a hole through green wire is no problem. Gee I wonder why this yellow wire has this green corrosion coating on it?

I made the above poster for my lab, in case Shabaz stops by for a beer with his meter. This technique has so many down sides, I have never taken up the habit in 37 years of working in electronics. Promoting this technique is a really bad idea.

This reminds me many years ago I saw an Electrician doing some measurements on the main voltage lines at home by poking them with Sewing pins. Maybe situations like these inspired such a useful tool.

If you want some really eye-watering prices for insulation piercing probes then check out Warwick supplies......

Insulation Piercing Probes

They also have a guide to them as well for the different types that are available.

Insulation Piercing Probe Guide

They are something I tend to stay away from, probably OK on low voltages, but I would have thought insulation damage on car harnesses that are subject to a lot of dirt and moisture would eventually lead to issues.

Kind regards.

24" probe... for when you really really dont want to get close.

The same company manufactures other really interesting probes and connectors as well.

Very interesting!

Piercing approach resembles RJ45 crimping mechanism as well.

Hi Shabaz,

They looked really useful until I saw the price. I think my application will need to be a bit more profitable before I invest.

Hey Shabaz! This is something new for me too. I never saw this kind of probes-connectors. Seems almost complex to build but also seems very efficient. The piercing approach of these probes resembles me the 80's network coaxial cables. It was possible to connect computer converters like network to centronics or serial using the tap-drill method. But I never saw something like this for decades.
