Allen-Bradley 872C-D8NP18-D4 8 mm PNP Inductive Proximity Sensor

The Allen-Bradley 872C-D8NP18-D4 Proximity Sensor is a three-wire DC inductive sensor from the Bulletin 872C WorldProx family. It uses a standard 18 mm tubular barrel and provides non-contact detection of metal targets with an 8 mm nominal sensing distance. The sensor features an unshielded configuration, a normally open source PNP output, and a DC micro quick-disconnect connection for integration into compatible machine wiring systems.

Product Features

The tubular design supports straightforward installation in machine frames, brackets, and equipment assemblies. Its chrome-plated brass barrel provides a structured mounting format for industrial sensing positions. The PNP normally open output is suitable for compatible control architectures, while the micro quick-disconnect interface can simplify sensor replacement and scheduled maintenance. The Allen-Bradley 872C-D8NP18-D4 Proximity Sensor can be used by OEMs and maintenance teams when configuring or replacing metal-detection points in compatible machinery.
