How should we wire the photoswitchs?

Basically, the three blue sensor wires ganged together and spliced with single 18AWG run to PDB ground. Same for three brown sensor wires to partner PDB 12v. run.

Kent,

You may want to consider powering it with 24 volts. One of the updates makes it legal by connecting the sensors to a solenoid output on the cRio and powering that module from the 24 volts from the PDB.

Previously in this thread I posted a plot of typical voltage during a match. The sensors are good down to 10.8 volts and we regularly see voltages below that.

Attached is the data sheet that shows the working voltage range of the sensor.
