Autonics PR12-4DN Proximity Sensor

The Autonics PR12-4DN Proximity Sensor from the PR Series is an M12 non-flush inductive sensor engineered to detect metal objects without contact. It offers a 4 mm sensing range, 12–24 V DC supply, and NPN Normally Open output with a residual voltage of just 1.5 V. Built to IP67 standards, it functions reliably between -25 °C and 70 °C. Compact, fast (500 Hz response), and durable, the Autonics PR12-4DN ensures stable detection in harsh industrial conditions and remains a dependable member of the Autonics Proximity Sensor lineup. In industrial automation systems, the Autonics PR12-4DN Proximity Sensor is widely used for metal detection and position control across conveyor systems, packaging machines, assembly lines, and material handling equipment. It maintains accuracy even in environments with high humidity or dust, serving critical roles in automotive, manufacturing, and food processing industries. Its M12 non-flush structure enables extended sensing capability while minimizing false triggers. The sensor’s oil-resistant PVC cable and vibration-proof design ensure reliable operation in compact control panels and automated robotic assemblies. Autonics Corporation, a global leader in industrial automation solutions, manufactures the PR12-4DN Proximity Sensor to meet strict quality and durability standards. Known for producing dependable sensors for OEMs and system integrators, Autonics products are trusted across India for accuracy, longevity, and ease of integration. Each proximity switch undergoes rigorous performance checks to ensure consistent output stability, noise resistance, and environmental protection. Backed by Autonics’ technical expertise and support network, the PR12-4DN delivers performance reliability engineers can depend on. Within the Autonics PR Series, the PR12-4DN represents the NPN Type, Normally Open configuration designed for automation systems that require signal activation upon metal detection. For control setups needing reverse logic, the matching variant is the PR12-4DN2, featuring a Normally Closed output while maintaining the same 4 mm sensing range, 12–24 V DC operation, and IP67 protection rating. Both models share identical M12 non-flush housing, electrical design, and mechanical strength. The PR12-4DN remains the preferred choice for Normally Open DC configurations, offering stable performance and long-term reliability within the PR Series family. The Autonics PR12-4DN Proximity Sensor combines compact M12 design, IP67 durability, and fast 500 Hz response to deliver precise, reliable metal detection in industrial automation. Operating on 12–24 V DC with an NPN Normally Open output, it is ideal for machine tools, conveyors, and packaging lines. Supported by Autonics’ trusted engineering standards and service network across India, the PR12-4DN ensures accuracy, stability, and long-term reliability for engineers and automation professionals.
