How to wire MF30 photocells?
Connect a 12/24V AC or 12/24/36V DC power supply to the TX and RX units. For the TX (transmitter), use the 12/24V and 0V terminals. For the RX (receiver), connect the power and the contact output terminals (COM, NC, or NO). Set the contact type using the selector and ensure the units are aligned.
