Photo Interrupter GP1A57HRJ00F Breakout Board

sku: BOB-09322 RoHS Compliant

Description: A simple breakout PCB for the GP1A57HR photo interrupter. This PCB has three connections for PWR, GND, and Signal.

When the gate is clear, SIG will be high (>4.9V). When the gate is blocked by a finger, writing utensil, food pellet, or anything else - SIG will go low (<0.4V).

Assembled picture is for reference only, board comes bare; photo interrupter and the 220Ω (330Ω, works as well) current limiting resistor are listed below.

    Hmm, unless I have done some completely faulty assembly, could your description be incorrect? My assembled breakout with interrupter and resistor looks just like the one depicted, yet SIG is high when the gate is clear, and goes low when the gate is blocked.

    Perhaps for the next version you could drill a hole for the locator lug.

  • liudr | about 2 years ago 1

    Agree! A hole for the locator lug. Plus, you said 220Ohm on silk layer but have a 330Ohm resistor on the assembled picture.

    • N8B | about 2 years ago 1

      Yeah, various resistor values work. Hence the 330ohm comment. Use whatever works best for your application. I said 220 because it worked when I was doing the layout for the PCB.
      The locator plug was also my mistake. The new ones should be on the storefront once the remaining 540 of these PCBs sell…this could take a while.

    HI. Is this possible to Do the opposoit with this breakout Board ?

    It would be nice if these boards had at least two holes for mounting the board to a surface. This board configuration requires the user to make a custom bracket or use double sided tape or bubblegum to mount it….
    And also, why would you continue to sell a product that you know is not up to par? This board is missing the hole for the alignment pin. Throw them in the garbage. I see that the qty in stock is pretty low now. So you have almost gotten all 540 of your known crap boards out. Good job. Put a disclaimer in the description for Pete’s sake stating that you have to cut parts of your sensor off to use this board as intended.

    RE: It would be nice if these boards had at least two holes for mounting the board to a surface.
    I second that. Don’t really want breakouts just hanging around esp for mounting the sensor where I am trying to detect a physical stopping point.

    I am happy to report that the versions of this board I just received have holes for alignment pegs, and the sensors pop in without modification.
    The lack of mounting holes is a serious problem, though.

    I want to use this item connected to a mainboard with a flat cable. Anyone know the spacing of the connector holes? Suggestions on flat cable connector would be greatly appreciated.

    Will this be back in stock soon?

    Many people have asked for this breakout board to include mounting holes. I had a need for that as well, so designed a replacement and had them made on BatchPCB. Just got the boards yesterday so did not have a chance to test them yet. The two screw holes line up perfectly to fit on a MicroRax beam profile.
