I added the external diode and it worked great. (No false triggers)
Thanks again for the help!

Cables, connectors, switches, contactors, sensors and other items / PNP Inductive Prox Switch Signal Always active on the pmdx-126 BOB

« on: July 25, 2016, 01:37:47 AM »

I have aquired several pnp contrinex sensors 100$ each (DW-AD-623-04) the current leakage is =<.1mA  when i hook up the sensor to the pmdx-126 board the light is on really dim when the switch is triggered the light gets bright on the board but in either case the signal to mach 3 is always on. How do i fix this problem. i heard npn sensor can have this this problem but no one has mentioned anything about pnp sensors. Any advise would be appreciated. Thanks!
