The Autonics PRL18-8DP2 Cylindrical Inductive Proximity Sensor offers an 8mm sensing distance optimized for 25Γ25Γ1mm iron targets. With a non-flush mounting type, it enables a wider detection range without the risk of false triggering from surrounding metal surfaces. The sensor operates on a DC 3-wire 12β24VDC supply and features a PNP Normally Closed control output, making it suitable for safety-critical systems where default operation must be βclosedβ in a fail-safe condition. It consumes less than 10mA and maintains a residual voltage below 1.5V, ensuring efficient signal transmission in low-power applications. The 350Hz response frequency provides quick output for moderate-speed automation lines, ideal for repeatable sensing cycles.
Its body is made from nickel-plated brass, with a sensing head constructed from high-durability polybutylene terephthalate. Rated to IP67, this model resists ingress from oil, dust, and moisture, and performs reliably in temperatures ranging from -25Β°C to 70Β°C. Whether installed on CNC panels or machine beds, it supports extended operation without recalibration. The long-body M18 design allows secure mounting even in deeper electrical enclosures. Built with standard and oil-resistant PVC cable options, the sensor is suitable for harsh operating zones where maintenance access is limited.

The PRL18-8DP2 is widely applied in metal part detection, packaging line verification, pallet position feedback, and industrial material handling systems. Its PNP Normally Closed output is ideal for fail-safe conditions, especially where loss of power must indicate a stop condition. Maintenance engineers prefer this model for its durability, fast response, and ease of wiring in retrofits or new installations. Automation students and trainees use this sensor in lab kits to understand closed-loop logic and real-time object sensing. Whether integrated into safety interlocks, limit detection, or part presence sensing, the PRL18-8DP2 supports dependable operation across industries and ensures reliable input to automation controllers.
