The Autonics PRD18-7DN features a 7mm sensing distance for detecting ferrous targets like 20Γ20Γ1mm iron plates with high accuracy. Designed with a flush-mountable M18 nickel-plated brass housing, this sensor integrates seamlessly into space-constrained industrial panels. It operates on a DC 3-wire 12β24VDC power supply and delivers an NPN Normally Open output, commonly used in PLC-based automation environments. With a maximum current consumption of 10mA and residual voltage below 1.5V, it ensures minimal power draw and noise-free signal output. The sensor is rated IP67, making it resistant to dust and water ingress, and is built to withstand ambient temperatures between β25Β°C and 70Β°C. A fast response frequency of 300Hz enables precise metal detection even in moderately high-speed operations. Its sturdy brass body and standard cable connection ensure reliability and ease of integration for engineers and panel builders.
Thanks to its shielded construction, the PRD18-7DN avoids false triggering in metal-dense surroundings and is ideal for mounting flush into machinery without interference. The sensor maintains consistent switching points over long-term use, which is essential for process stability in production lines. Maintenance teams benefit from its low-maintenance design, while project engineers value its compatibility with various control systems and legacy architectures.
The Autonics PRD18-7DN Long-Distance Inductive Sensor is widely used in automatic conveyors, machine tool monitoring, elevator systems, packaging machines, and robotics. It supports accurate, contactless detection of moving components and metallic objects, helping prevent collisions and ensuring safe system performance. Engineering students and junior technicians can install and troubleshoot this sensor with ease, while experienced engineers rely on it for precise positioning and real-time detection in complex automation flows.
