Autonics PR12-4AC 100-240VAC Cylindrical Inductive Proximity Sensor

The Autonics PR12-4AC is an M12 cylindrical inductive proximity sensor designed for non-contact detection of metallic objects in industrial automation applications. It operates with a 100–240 VAC AC 2-wire power supply and provides a normally closed output with a nominal 4 mm sensing distance. The sensor features a durable nickel-plated brass body, red LED status indication, and an IP67-rated protection structure, making it suitable for machinery, conveyors, packaging equipment, and position-detection applications.
