24VDC Sensor Wiring | SICK WL12 Digital Out Sensor Allen Bradley M12 Connector

24VDC sensor wiring is a critical task in nearly every control systems installation.

The standard colors of a 24VDC sensor wiring in Allen Bradley are brown, white, blue, and black. These four wires represent the signal of 24VDC, signal, 0VDC, and signal2.

Powering a sensor is simple:

  1. Connect the 24VDC and 0VDC signals to the brown and blue terminals.
  2. Connect the white and black signals to a PLC or control system.

It’s important to note that the signals may differ between sensors, brands, and applications. Make sure to review accordingly.
