Product description

The Allen Bradley 872C-A5N18-N3 is a 3-wire DC inductive proximity sensor designed for detecting metallic objects without physical contact. It features an 18mm diameter nickel-plated brass barrel with a standard barrel type and a sensing range of 5mm. This sensor operates with a voltage range of 10-30V DC and provides a Normally Open (N.O.) output, meaning the circuit is completed when a metallic object is detected. It is a shielded sensor.

This DC-powered sensor is suitable for a wide array of industrial automation applications, particularly where interfacing with DC control systems or PLCs is required. Its 18mm barrel and 5mm sensing range make it versatile for use in machine tools, assembly lines, and material handling systems. The N.O. configuration is standard for presence detection.

Stanlo Automation, a veteran-owned surplus industrial parts distributor, offers the Allen Bradley 872C-A5N18-N3. We pride ourselves on providing reliable surplus automation components to help you maintain your operations cost-effectively.
