Allen Bradley's 872C-N12NP18-D4 is a cylindrical proximity sensor belonging to the Bulletin 872C family. Designed for inductive applications, the sensor measures 18 mm in diameter and extends 76.5 mm in length. Its nominal sensing distance is calculated at 12 mm, allowing for reliable detection of metal objects within that range.

Powering the sensor requires a direct current (DC) voltage ranging from 10 to 30 volts, providing flexibility in various installations. The output configuration is normally open (N.O.) with PNP functionality, which is suitable for multiple control schemes. It can switch frequencies reaching up to 1500 Hz, highlighting its capability of quickly detecting changes in proximity.

This sensor is classified under an IP67 rating, indicating solid protection against dust ingress and temporary immersion in water. The absence of shielding enhances its functionality within certain applications. Furthermore, it comes equipped in a Micro QD style, supporting straightforward connection setups for efficient integration into control systems.
