Product description

The Allen Bradley 871A-TS3-N2 is a high-performance inductive proximity sensor designed for reliable metallic object detection in industrial settings. It features a 3mm sensing range and an NPN output with normally closed (NC) contacts. This sensor operates on a 10-30VDC power supply and is housed in a durable M12 threaded stainless steel body, ensuring robust performance.

This sensor is suitable for applications requiring fail-safe operation, such as machine guarding, safety interlocks, and presence detection where the absence of an object should trigger a signal. It is commonly used in manufacturing, material handling, and packaging industries.

Stanlo Automation, a veteran-owned surplus parts distributor, offers the Allen Bradley 871A-TS3-N2. We are committed to providing quality industrial automation components at competitive prices, ensuring your operations remain efficient and uninterrupted.

Frequently asked questions

How does the normally closed output function on the 871A-TS3-N2?

The 871A-TS3-N2's NPN NC output is conductive when no metallic object is present in the sensing range. When an object is detected, the output opens, signaling its presence. This is crucial for fail-safe operations.
