220v explosion proof limit switch , hazardous location limit switch

Description:

The explosion proof limit switch is a commonly used small current main electric appliance. The collision or control circuit is realized by the collision of the moving parts of the production machinery to make the contact action to achieve a certain control purpose. Typically, such switches are used to limit the position or travel of the mechanical motion, allowing the motion machine to automatically stop, reverse, shift, or automatically reciprocate at a certain position or stroke.
In the electrical control system, the role of the limit switch is to achieve sequential control, positioning control and position status detection. Used to control the travel and limit protection of mechanical equipment. Construction: consists of the operating head, the contact system and the housing.

Application:

1. Can be used in hazardous areas: Zone 1 and Zone 2 .

2. Can be used in explosive gas atmospheres of Category IIA and II B IIC where the temperature classification is T6.

3. Two type of Ex d(IIB) and complex(IIC).

4. Flammable dust atmosphere.

5. Widely using in the fields of oil, chemical industry , spaceflight ,war industry and so on.
