Product description

The Allen Bradley 872C-A5N18-A2 is a 2-wire AC inductive proximity sensor designed for non-contact detection of metallic objects. It features an 18mm diameter nickel-plated brass barrel with a standard barrel type and a sensing range of 5mm. Operating within a voltage range of 20-250V AC, this sensor provides a Normally Open (N.O.) output. It is a shielded sensor, equipped with a 2-meter 2-wire PVC cable, and boasts an IP67 enclosure rating for durability in industrial environments.

This sensor is widely used in automation applications where the presence of a metallic object needs to trigger an event. Its 18mm barrel diameter and 5mm sensing range are suitable for various machine designs, including conveyor systems, robotics, and packaging machinery. The N.O. output is standard for detecting the presence of a target.

Frequently asked questions

What is the typical application for an Allen Bradley 872C-A5N18-A2 inductive proximity sensor with a Normally Open output?

A Normally Open (N.O.) output on the 872C-A5N18-A2 means the sensor's circuit is open (no current flow) when no metallic object is detected. It closes (allows current flow) when a target enters the sensing range. This is ideal for detecting the presence of parts on a conveyor or confirming a machine component's position.
