Product Description

Types of Proximity Sensor Metal Proximity Sensor (LJA30)


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
