Product description

The Allen Bradley 872C-D3NN12-D4 is a versatile industrial inductive proximity sensor for non-contact detection of metallic objects. It provides a 12mm sensing range and features a 3-wire, NPN normally closed (NC) DC output. This sensor is designed to operate with a wide voltage input of 20-264V AC/DC and is housed in a durable metal body with a plastic sensing face, ensuring robust performance in industrial environments.

This NPN NC sensor is ideal for applications in manufacturing, material handling, and automation where reliable detection of metallic targets is required. It is commonly used for presence sensing, positioning, and interlock functions in conjunction with PLCs and control systems that accept NPN outputs.

Stanlo Automation, a veteran-owned surplus distributor, offers the Allen Bradley 872C-D3NN12-D4. We are committed to providing high-quality, cost-effective industrial automation components. Source your essential surplus parts from Stanlo Automation and ensure minimal disruption to your operations.

Technical note

Expert tip

When wiring an NPN normally closed sensor, connect the load between the sensor's output and the positive DC voltage supply. The output transistor sinks current to ground when a target is detected.

Frequently asked questions

What is the output configuration of the Allen Bradley 872C-D3NN12-D4 sensor?

The Allen Bradley 872C-D3NN12-D4 is a 3-wire DC inductive proximity sensor with an NPN output that is normally closed (NC). This means the sensor's output is connected to the negative DC supply, and it is open (no signal) when no target is detected within its 12mm sensing range.
