Can you hook the photo sensors to one 12 volt out??

With the resistor between the 5V and the signal, what you did is create a pull-up for the circuit using a pull-up resistor.

The Digital Sidecar DIO pins are internally pulled up to 5V using 10K resistors.

Sweet! Always a cool thing to learn something. So do the sensors work fine with the internal 10K ohm?

They work perfectly. It's almost as if the Digital Sidecar was designed to handle open-collector sensor outputs directly.

Please be advised that the PD terminals work best and most reliably with #18 AWG wire or larger.
