Allen-Bradley 871C-DE4NP12-D4 Inductive Proximity Sensor

The Allen-Bradley 871C-DE4NP12-D4 Inductive Proximity Sensor is a 12 mm cylindrical inductive proximity switch designed for non-contact detection of metallic objects in industrial metal detection and positioning systems. It features a 4 mm sensing distance, PNP Normally Open (3-wire DC) output, a 10–30 V DC supply, and up to 200 mA output current, with a nickel-plated brass housing and threaded barrel for durable mounting. IP67-rated for dust, oil, and vibration resistance, it is commonly used on conveyors, packaging machinery, and automated assembly lines to provide reliable object sensing and precise positioning, and it serves as a common replacement or retrofit part within Allen-Bradley/Rockwell Automation installations.
