The automatic control switch, a large number of used in the system of industrial and mining enterprises,protection switch, limit switch detection switch is the rotation of the machine production workshop (or linear)motion parts or products of travel, the important position, protection, detection and location of the automatic control switch. When the object is moving to the specified location, the mechanical impact under the action of a switch to be switched on or off the action signal, complete the relevant equipment or institutions need action control. Due to mechanical impact on switching mechanism makes easy to break and wear and contactinductance electromotive force under very high in the open under the burning arc contact early, cause the switch spare parts consumption. Even as the action failures, downtime, production, human casualties and major equipment failure, over the years is a long-standing problem in the production of the factory.

Magnetic induction proximity switch after years of research, has been successfully applied to production, to solve the above problem. Method of use: it is when the object to be detected close to a certain distance, do not need to contact will be able to issue a switch or low level signal detection, is a black metal has no sensors within a certain distance, can directly drive the load (such as contacts, electromagnetic valve, relay and PLC etc.).Because it has the advantages of no mechanical abrasion, high sensitivity, reliable operation, high repeat positioning accuracy, fast operating frequency, vibration resistance, waterproof and long service life, can directly replace the control system with contact, easy to wear, short service life of the stroke switch, position switch, protection switch, switch, position detection switch, widely Department of metallurgy, machinery, formine, traffic, light control system, automatic stop, automatic positioning, safety protection, logic control,automatic detection, automatic counting, automatic measurement and assembly etc..
