RIKO SN04-N NPN Inductive Proximity Sensor

This SN04-N NPN NO 5mm Distance Detector Proximity Sensor Switch Module is designed as a high-frequency oscillation type. This induction proximity sensor is capable of transmitting a detection signal quickly. This distance detector proximity sensor detects the presence of a metallic object within a range of 4mm of the surface of the sensor. The detection distance varies slightly based on the shape, size, and also the sort of metal or the metal made from. It can detect through thin, non-metallic materials and has an LED indicator that activates when the device is powered and increases in brightness when an object is detected.

Metal detectors are widely used for finding metal inclusions hidden within objects, or metal objects buried underground. This detector module basically consists of a handheld unit with a sensor probe that swept over the bottom or other objects. This NPN type Inductive Proximity Sensor is also called a proxy switch. This Square Type low cost waterproof and dustproof proximity sensor with an LED indicator and also ensures easy Mounting.

When a target is detected the detector generates an audible response, like a beep or change in tone. Basically, the device gives some indication of distance; which suggests the closer the metal is, the higher the tone within the earphone or the higher the needle goes. This distance detector features high sensitivity, fast frequency response, and also high repeatability. Moreover, the SN04-N Sensor is extremely easy to use are often used with PLC for CNC applications.
