5mm sensing range 2-wire AC operation Normally Closed (N.C.) output 18mm diameter barrel Shielded design 20-250V AC voltage IP67 rated

The Allen Bradley 872C-A5C18-A2 is a 2-wire AC inductive proximity sensor designed for non-contact detection of metallic objects. It features a robust 18mm diameter nickel-plated brass barrel and a standard barrel type with a sensing range of 5mm. This sensor operates on 20-250V AC and provides a Normally Closed (N.C.) output. It is a shielded sensor, comes with a 2-meter 2-wire PVC cable, and is rated IP67 for protection against dust and water ingress.

This sensor is ideal for applications requiring a normally closed output, meaning the circuit is completed when a metallic object is NOT detected. Its 18mm barrel size and 5mm sensing range make it suitable for a variety of industrial settings, including automated manufacturing, material handling, and packaging machinery where space and specific output logic are critical.

What is the significance of the 'C' in the Allen Bradley 872C-A5C18-A2 part number for its output configuration?
The 'C' in the Allen Bradley 872C-A5C18-A2 part number denotes that the sensor has a Normally Closed (N.C.) output configuration. This means the electrical contact is closed (allowing current flow) when no metallic object is within the sensing range and opens when a target is detected.
