Product Description

CHJ8 Inductive proximity switch



Description

Proximity switch is one of position switches. When it operates, no need to make a mechanical 
contact. It is also called no contact switch. As soon as the detected object approaches to the 
surface of the sensor distance range, It begins to act with no contact, no pressure form, then 
drive AC or DC electrical or computer equipment to provide control instructions.
C. Lin brand proximity switches covers: Inductive proximity switches, Capacitive proximity switches, 
Hall sensor, photoelectrical sensors. They are widely used in machinery, texitle, metallurgy, tobacco, 
railway, war industry and so on

Maintenance and overhaul
In order to ensure long-term stable operation of the proximity switch, please carry out the following periodic inspections;

1. Check that the installation position of the detection object and the photoelectric switch is offset, loose, and deformed.

2. Check the wiring, whether the connection part is loose or not, and the contact is broken.

3. Check for any deposits such as sticky metal dust.

4. Check the operating temperature and whether there are any abnormalities in the surrounding environment.
