R315LA Wireless Proximity Sensor

   

R315LA is a proximity sensor that detects an object’s presence or approach by measuring the distance between the sensor and the object. With a 62cm measurement range, it is suitable for short-range measurements, such as toilet paper detection. In addition, R315LA is small and light in weight. Without time-consuming and complicated installation methods, users can easily fix R315LA on a surface and get accurate measurement results.
