Frequently asked questions

What is the purpose of the Normally Closed (NC) output on the 871D-DW2NP524-D4 sensor?

A Normally Closed (NC) output on the 871D-DW2NP524-D4 means the sensor's output circuit is conductive when no metallic object is present. When an object is detected, the circuit opens. This is often used in safety circuits where the absence of a signal indicates a fault or an unsafe condition.
