The Autonics PRDL12-4DP delivers a 4mm sensing distance using a 12Γ12Γ1mm iron target, offering precise proximity detection even in tightly packed industrial panels. Built with a nickel-plated M12 brass housing and long-body form factor, this sensor is designed for durability and installation depth flexibility. It operates on a DC 3-wire type 12β24VDC supply and delivers a PNP Normally Open control output, making it compatible with standard PLCs and automation controllers. With current consumption capped at 10mA and residual voltage below 1.5V, it ensures stable, energy-efficient operation. The sensor is protected by an IP67-rated enclosure, making it dust-tight and water-resistant. Its fast response frequency of 500Hz supports rapid switching in motion-critical systems. It functions reliably in ambient temperatures ranging from β25Β°C to 70Β°C and humidity levels up to 95% RH, ensuring dependable performance in both indoor and semi-exposed environments.
Thanks to its flush-mount design, the PRDL12-4DP can be installed directly into metal machine surfaces without interference from surrounding conductive materials. Its long body provides secure seating in deep mounting slots, often required in control cabinets, sensor brackets, or mobile equipment frames. Engineers prefer this sensor for its balance of compact diameter, long detection range, and robust signal outputβcritical for high-precision automation tasks.
The Autonics PRDL12-4DP Long-Distance Inductive Sensor is widely used in robotic end-effectors, control panel automation, metal part feeders, indexing stations, elevator doors, and proximity feedback loops. Whether it's monitoring fine metal components or triggering control logic in dynamic environments, this sensor delivers reliable performance with minimal setup time. Technicians and engineers trust its accuracy, fast response, and solid build quality for day-to-day factory operations.
