The Autonics PRD12-4DN2 is a high-precision Long-Distance Inductive Sensor with a 4mm sensing range, optimized for detecting standard 12Γ12Γ1mm iron targets. Built with a flush-type M12 sensing face and operating on a DC 3-wire system (12β24VDC), this sensor uses a NPN Normally Closed output. It consumes a maximum of 10mA current and operates with residual voltage β€1.5V, ensuring energy-efficient detection and minimal signal drop. The sensor supports stable operations across a wide temperature range of -25 to 70Β°C and can be stored from -30 to 80Β°C. Its construction features nickel-plated brass housing and an IP67 protection rating, offering full resistance to dust and water ingress. With a response frequency of 500Hz, the sensor provides quick detection feedback in high-speed environments, making it highly dependable for precision applications in tight industrial layouts.
The PRD12-4DN2 is best suited for use in automation lines, packaging equipment, robotic arms, and metal part position detection where flush mounting and reliable signal integrity are critical. Maintenance teams and control engineers prefer this sensor for its plug-and-play compatibility with PLC systems, low power consumption, and robust mechanical design. Whether monitoring product flow on conveyors or ensuring component alignment on machines, it performs with consistent accuracy while reducing maintenance time and costs. Its shielded construction minimizes false triggers in harsh industrial zones, enabling smooth integration in both new installations and retrofit systems.
