Proximity switches, also known as contactless proximity switches, are ideal electronic switch quantity sensors. When the metal detection object approaches the sensing area of the switch, the switch can issue an electrical command without contact, pressure or sparks, accurately reflecting the position and stroke of the moving mechanism. Even for general stroke control, its positioning accuracy, operating frequency, service life, ease of installation and adjustment, and adaptability to harsh environments It is incomparable to the general mechanical limit switch.

It is widely applied in industries such as machine tools, metallurgy, chemical engineering, light textile and printing. It can be used as a limit, counting, positioning control and automatic protection link in an automatic control system. Proximity switches feature a long service life, reliable operation, high repeat positioning accuracy, no mechanical wear, no sparks, no noise, and strong vibration resistance. Therefore, up to now, the application scope of proximity switches has been increasingly wide, and the speed of their own development and innovation has also been extremely rapid.
