Frequently asked questions

What type of output does the Allen Bradley 871TM-B4N12-C2 proximity sensor have?

The 871TM-B4N12-C2 features an NPN normally open (NO) output. This means that when the sensor detects a metallic object, it provides a path for current to flow from the output to the negative supply.
