Question

Can I connect only two wires of a 4-wire sensor?

Answer

A 4-wire sensor is designed for use of at least three of the four wires. Two of the wires are used to power the sensor (+ and - voltage). The other two wires are used for outputs, either a Normally Open (N.O.), Normally Closed (N.C.) output, or both outputs. The sensor will not operate as a 2-wire device.
