Product description

The Allen Bradley 872C-NH12NP18-D4 is an inductive proximity sensor featuring an 18mm sensing face and a 12mm barrel. Constructed with durable nickel-plated brass, it provides a Normally Closed (NC) output for 120V AC operation. This sensor is designed for reliable detection of metallic objects, especially in applications requiring a longer sensing distance and NC functionality.

This NC output sensor is valuable for safety-related applications, such as ensuring a gate is closed or a part is absent before a process can begin. Its extended sensing range makes it suitable for larger machinery and automated systems in manufacturing and logistics.

Stanlo Automation, a veteran-owned surplus distributor, offers the Allen Bradley 872C-NH12NP18-D4. Secure your critical automation components from a trusted provider focused on quality and value.
