Tips: Unshielded proximity sensor installation notes
The installation of unshielded proximity sensor will encounter many problems. For example, there is interference between proximity sensor and mounting bracket and mutual interference between proximity sensors etc.
- If a proximity sensor is installed in a metal bracket, its height of proximity sensor should be more than two times longer than the detection distance. The surrounding metal distance should be as long as the diameter of proximity sensor in order to avoid the influence of bracket.
- As for the distance between proximity sensors, the face to face installation distance should be two times longer than the detection distance and the side-by-side distance should be two times longer than the diameter of proximity sensor.
M24 proximity sensor can detect a variety of metals, small size, long life, unshielded type installation, anti-interference ability, 10mm detection distance, supply voltage DC 12V, manufacturer direct sale.
