SN04-N NPN NO Proximity Sensor – 5mm Inductive Distance Detector 6–36V

The SN04-N NPN NO Proximity Sensor is a reliable and durable inductive sensor designed for detecting metal objects at close range. Operating on a wide voltage range of 6V to 36V, this sensor is ideal for industrial automation, robotics, and smart systems where non-contact metal detection is required. It features a 5mm detection distance and NPN Normally Open (NO) output configuration for versatile integration.

Thanks to its compact design and IP67-rated enclosure, the SN04-N sensor performs well in harsh environments, providing consistent operation even in dusty or wet conditions. With a fast response frequency of up to 500Hz, it can be used in systems that require rapid detection and switching. A built-in LED indicator provides real-time feedback for power and object detection status.
