SmartBOB controllers and dedicated accessories / PMDX 411 and Connecting Proximity Sensors

« on: February 12, 2018, 07:08:12 PM »

For my limit switches can I connect my proximity sensors directly to the parallel port pins?

I was planning to use X Y and Z two sensors each in parallel on pins 11,12 and 13.

Can I connect the switches with brown wire to 24 volt from the main board, blue wire to ground and black wire to the respective pin 11-13?

They are NPN switches.
