The Autonics PRD18-7DP offers a reliable 7mm sensing distance using a standard 20×20×1mm iron target, ideal for detecting ferrous objects in tight machine setups. This model features a shielded flush-type M18 brass housing with nickel plating, allowing it to be mounted directly into metallic surfaces without sensing interference. It operates on a DC 3-wire 12–24VDC input and delivers a PNP Normally Open output, which is widely used in industrial automation for its simplicity and compatibility with PLC systems. With maximum current consumption of 10mA and residual voltage under 1.5V, the sensor ensures efficient power usage and accurate signal transmission. Rated IP67, it is dust-tight and water-resistant, and performs consistently in harsh conditions from –25°C to 70°C and humidity levels up to 95% RH. Its 300Hz response frequency supports fast switching applications without delay or loss of signal accuracy.
This sensor’s flush-mount design ensures that it can be embedded within machinery panels or metal housings without compromising detection range or stability. Its compact body and standard cable make installation quick and straightforward for engineers working on control panels or robotic systems. The consistent output and minimal hysteresis provide reliable detection even in vibration-prone environments or with repetitive machine movement. With minimal maintenance required, this sensor is a dependable component in systems that run continuously or in high-cycle operations.
The Autonics PRD18-7DP Long-Distance Inductive Sensor is widely used in automated conveyors, packaging lines, robotic arms, elevators, part feeders, and safety interlocks. In each of these applications, it delivers precise metal object sensing, protecting machinery from collisions and ensuring seamless automation flow. Industrial engineers value this sensor for its fast response time, flush installation design, and robust environmental resistance. Maintenance teams appreciate its ease of replacement and low failure rate. For more Autonics sensors, visit our Autonics Proximity Sensor Page or learn about the brand at our Autonics Brand Page.
