High temperature resistance switch

Overview:

High-temperature trip switch is actually a special type derived from the trip switch. It is generally used in high-temperature equipment or in high-temperature environment. It can withstand high temperatures to make the product's performance unchanged, stable and normal work, and solve the problem of excessively high temperature. The trip switch can not withstand the frequent replacement of the trouble, not only can improve the equipment's working time and equipment use time, but also increased the high economic efficiency, deeply welcomed by high temperature equipment and supporting manufacturers.

The high temperature resistance stroke switch is made of all-metal aluminum alloy. The interior of the switch adopts a fully-enclosed contact switch made of high-temperature resistant material and a set of normally open one set of normally closed maximum allowable current of 5A/AC 220V (other voltages are accepted ), The contacts can be used under high temperature for prolonged use without being oxidized or contaminated resulting in damage.

Products are widely used in power, chemical, petroleum, textile, steel and other high temperature environment equipment industry.

Product Categories:

According to the different operation types of high-temperature stroke switch, it is divided into cylindrical plunger type (NHD1, NHG1), roller plunger type (NHD2, NHG2), handle roller arm type (NHY1, NHGB), handle roller arm adjustment type (NHY2, NHGC), rod adjustment type (NHL1, NHGL), ball plunger type (NHD3, NHG3), U type double roller lock type (NHY3, NHGD), spring universal type (NHA5, NHG5), etc.

Use environment:

1, the ambient temperature: the highest temperature +550 degrees, the lowest temperature -30 degrees

2, altitude: no requirements

3, environmental humidity: the relative daily average is not greater than 95%

Application advantages:

1. Application in high temperature places: The product is a full-metal aluminum alloy structure, and the internal high-temperature material is cast into a fully-sealed electric shock switch, which can be suitable for extremely good operation under extremely high temperature and harsh environments.

2, low temperature applications: The product has a good low-temperature performance, can meet the requirements of most of the low-temperature equipment production

3, plateau applications: all-metal aluminum alloy structure, no need to consider the impact of air pressure on the product shell deformation

4. Application in explosion-proof places: The inside is a fully enclosed switch, and the external metal high-temperature and explosion-proof cable connector has good sealing performance and can isolate the corresponding dust well.

5. Frequently operated places: The mechanical life of the high-temperature resistance travel switch is 15 million times

Common features of all models

2-circuit double-break operation

Use 2 circuits double break to ensure the circuit is cut off.

IP65 protection rating

The use of aluminum alloy casing and metal threading protection cover can meet the demand of high temperature environment.
