Poll: Are you interested in roadtesting an Reflective Optical Sensor board?

I was contacted by the sponsor who would like their optical sensor board roadtested. I'd like to get your interest in roadtesting it.

 

tt electronics reflective optical sensor modulex

 

The OPB9001 PCB module takes the versatile and programmable OPB9000 reflective sensor and enhances its capabilities by integrating multiple features into a robust, small form factor for ease of use. The OPB9001 accepts a wide range of supply voltages from 3.3V to 30 V and comes with built-in voltage protection for maximum flexibility and protection. An integrated, industry standard 4-pin Molex connector provides ease of connection while the onboard LED indicators provide overall status during power-on, output and calibration.

 

The OPB9001 is designed for portability in a variety of position and presence detect applications, with a small form factor (188 mm x 12 mm x 5 mm) to fit in even the smallest application spaces. The full-featured OPB9001AC includes a robust Transient Voltage Suppressor (TVS) diode to protect against harmful voltage spikes and is CE and UL certified for maximum reliability under any environmental condition. It is also capable of withstanding up to 8 kV of contact discharge HBM.

 

Factory calibrated for a 12 mm distance and a white reflective surface the OPB9001 can be re-calibrated in a matter of

milliseconds with a single command for specific application requirements. An interface cable can be purchased separately to

calibrate the OPB9001 Series using the OPB9000-KIT

 

  • Wide operating supply voltage range up to 4.5 V - 30 V
  • Detecting distance 2.5 mm to 50 mm
  • Ambient light rejection 25k+ lux
  • Programmable output configuration and sensitivity level
  • Integrated 4-pin connector
  • -40ÂC to +85ÂC operating temperature range
  • Small dimensions L 18 mm X W 12 mm X H 5 mm

    With a 6ms response time, you could use it as a RPM sensor on most motors. Scott

    This looks like a useful device. Is it possible to get the calibration kit for the road test? The datasheet doesn't exactly spell out how to calibrate. Will have to look around for that manual.

    the datasheet says it is for presence detection within 50 mm. I hope it would come with a breadboard friendly adapter for its connector.

    I feel I must be missing something here as I am not quite sure what this is for. It seems quite expensive to just be able to detect something at short distance, I have some micro switches will do this and cost much less.

    I missed seeing this earlier : ( Optek/TT Electronics seems to be the go-to manufacturer for such sensors, especially now that Honeywell no longer produces optical sensors.

    It could be a good candidate for replacing the IR diode and the obsolete Honeywell sensor used in this project: Cyclops-1000: An Electronic Eye for Rotational Speed Measurement

    Although I think the Optek/TT Electronics OPL800 series, e.g. OPL820 may be a closer drop-in replacement for the existing design (unfortunately no UK stock currently to try that out).

    That will really help road testers do a full evaluation. Thanks for chasing it down.

    Douglas,

     

    This is what the sponsor told me will be in the roadtest kit:

     

    The interface cable and the OPB9000-Kit will be included in the road test.  We will also be sending the OPB9001AC which is the finished product with the OPB9000 on it. And the cable that goes from the eval kit to the board will also plug into this part number.

    I see. Thank you. 50mm is short, though.

    When I read the headline, my 1st thought was: I am going to take this for a roadtest, literally. Strap in to the car and measure pot hole depth while driving.

    But then I saw the specs: max 50mm and only 1bit (ADC) out. image

    The board looks like it could be used for a building entrance detector or access.

     

    The outputs look like they are meant to drive a relay or turn on a motor, hence the EMF voltage protection.

     

    They are suggesting that the detection can be made in a wide range of ambient light conditions, which implies a good deal of input discrimination so you just cannot shine an LED or use a mirror to hit it with sunlight.

     

    Could be useful for some interesting projects.

     

    Hopefully the cable will come with it along with access to the software.

    Thanks Douglas.

    That's why I'm trying to run these polls: I'll ask about the calibration kit.
