Product description

The Allen Bradley 871A-TR5-D1 is an industrial inductive proximity sensor designed for reliable detection of metallic objects. It offers a 5mm sensing range and utilizes an NPN output with normally closed (NC) contacts. The sensor operates on a 10-30VDC supply voltage and is housed in a durable M12 threaded stainless steel body, suitable for challenging environments.

This sensor is ideal for applications requiring fail-safe operation or where a signal is needed when an object is NOT present. It's commonly used in machine safety circuits, material handling, and automated manufacturing processes where precise and dependable detection is crucial.

Stanlo Automation, a veteran-owned surplus parts distributor, is your source for the Allen Bradley 871A-TR5-D1. We specialize in providing quality automation components, ensuring you get the parts you need to keep your operations running efficiently at a competitive price.
