The Autonics PRD12-8DN2 sensor delivers an effective 8mm sensing distance using a standard iron target of 25×25×1mm, supported by non-shielded (non-flush) mounting for better range. Built with a durable nickel-plated M12 brass body, it operates on a DC 3-wire type 12–24VDC and consumes a maximum of 10mA. Its NPN Normally Closed control output is ideal for logic-based automation systems. With a residual voltage ≤1.5V, this sensor ensures clean, reliable signal transmission with minimal electrical noise.
Rated at IP67, the PRD12-8DN2 offers excellent ingress protection for use in dusty or wet environments. It withstands operating temperatures from –25°C to 70°C and supports humidity levels from 35% to 95% RH, making it suitable for both indoor and outdoor industrial applications. With a response frequency of 400Hz, it’s capable of detecting fast-moving metal targets in high-speed systems. Its robust design and standard cable type ensure long-term stability and easy installation for maintenance teams.
The Autonics PRD12-8DN2 Long-Distance Inductive Proximity Sensor is trusted for applications such as automated conveyors, machine safety interlocks, feeder systems, robotic part positioning, and elevator mechanism sensing. Junior engineers prefer its ease of wiring and fast detection, while senior engineers value its reliable range and compatibility across legacy and PLC-based systems. It solves common proximity issues in high-speed lines and moving machinery where consistent, non-contact metal detection is critical.
