3 pin npn LJ12A3-4-Z/AX proximity switch help

[RobC]

Actually I just noticed, my input for the 24v is incorrect as It's a PSU in not an out as I have connected but I tried it earlier connected to the stepper driver PSU and had the same issue.

is this how you connected the power suppy and proximity switch to the breakout board ?



if the breakout boards power supply negative in terminal is
connected to the limit switch common ground by the PCB's copper tracks it should work

but you may have to move the power supplies negative connection to the BOB's negative in to avoid noise problems
triggering the inputs
