Model description:

The characteristic of an electromagnetic switch lock is that it has a separate separate operating component (also known as a plug or operating key). The use of electromagnetic switch locks must achieve the following functions:

-Can ensure that the machinery and equipment will not produce dangerous movements when the safety protection door is opened;

-If an electromagnetic switch lock is used, the movable safety protection door must remain locked until the operating state of the machine equipment does not cause the occurrence of dangerous situations;

-Closing movable protective doors will not directly initiate dangerous actions of machinery and equipment.

When the time for the dangerous action of the machine equipment to stop is greater than the time required for personnel to enter the dangerous area, a safety electromagnetic switch lock must be used, which has the functions of safety locking and delayed unlocking release.

Electromagnetic switch locks come in two series: insulated plastic shells and metal shells. The choice of series depends on the environmental conditions they are in, including mechanical loads, temperature, chemical effects, etc. BN20-10Z-M16，BN20-10Z-M16Explosion proof limit switch
