CHJ8 Rectangular

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 Model meaning

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. Outline dimension:
