Proximity sensor PCB for Rigidbot (24v)

thingiverse

Made a printable PerfBoard for a Proximity sensor according to these schematics from Mr. Dennis Brown. Compatible with all controller boards: http://rigidtalk.com/wiki/index.php?title=Proximity_Sensor\nPrinted at .14mm layer, 100% infill.\nPS: Unless your printer is very accurately calibrated you might need a ~1mm drillbit to clear the holes.\nTried to make it as space efficient as possible. LM8UU Sized Drylin bushing for size comparison in one of the pictures.\nNB: Wiring in picture is wrong, tried it on my own printer today and I misread the PC817. Schematic is correct, I just read it wrong. So don't follow pictures for wiring. Will update with new wiring and possibly new PerfBoard.\nIf you want to make your own you need:\n2.54mm Terminal Block 3-pin 1x\n2.54mm Terminal Block 2-pin 1x\nOptocoupler PC817 1x\n4k7 resistor 1x\n1N4148 diode 1x\nPerf. Board 1x\n*LJ12A3-4-Z/BX Prox.
