Polyfunctional Electronic Proximity Sensor Dust Proof IP67 Protection Structure
Description
The electronic proximity switch is a position switch that can be operated without mechanical direct contact with moving parts, when the object approaches the sensing surface of the switch to the operating distance. It is widely used in machine tools, metallurgy, chemical, textile and printing industries. It can be used as a limit, counting, positioning control and automatic protection link in the automatic control system.

About maintenance and overhaul
In order to keep the proximity sensor to work stably for longtime, the following regular examinations should be performed just like general control
1. Check the installation position of detected object and proximity sensor if any deviation,loosening or deformation exists.
2. Check the attached wires and connecting parts if any loosening,bad contact or wire breaking off exists.
3. Check if there is any metallic powder accumulation or not.
4. Check if the temperature condition and surrounding environment condition are normal or not.
