Features 1、Approach Sensor: The magnetic switch can be directly installed on the cylinder block. When the piston with the magnetic ring moves to the position of the magnetic switch, the two metal springs in the magnetic switch are attracted by the magnetic ring magnetic field and send a signal. When the piston moves away, the switch ring leaves the magnetic field, the contact automatically opens, and the signal is cut off. In this way, it is convenient to detect the position of the cylinder piston. 2、Wide Application: Magnetic switches can be used as sensors for counting, limiting, etc. It is mainly used in the production of door magnet and window magnet in the security system. It is widely used in printers, fax machines and other electronic equipment. It is also widely used in various communication equipment. 3、Sensitive Switching: One or more points of magnetic spring switch can be set, and then the pipe can be penetrated through one or more hollow floating balls with ring magnets inside, and the fixed ring can be used to control the floating ball and magnetic spring switch at relevant positions, so that the floating ball can float up and down within a certain range. Use the magnet in the floating ball to attract the contact of the magnetic spring switch to generate the opening and closing action. 4、Stable Working: With a certain magnetic field, it has relatively good anti interference ability and can play a good role in relatively complex environment to ensure the normal operation of the equipment. 5、Easy to Install: Ensuring stable switching, the magnetic proximity sensor with a light weight and a compact size is very flexible to install in narrow spaces to prevent breaking.
