Brief Introduction:
 
 
 
The interior adopts high temperature resistant, totally enclosed contact switches whose maximum allowable current is 5A/AC 220V. Through special processing to the contact, the switch can be used in high temperature environment for a long time without failure from oxidization or pollution.
 
The highest temperature of NH series is 350, while the long term working temperature is 250. As for NHG series, the highest temperature is 650, while the long term working temperature is 550 . It has filled the domestic blank of ultra-high temperature switch field. Every switch has roller, adjustable rod, pressure plunger to meet your different needs. It is widely used in electrical power, chemical industry, petroleum, textiles, steel and other industries.
 
 
 
 
 
Contact type:
 
 
 
Characteristics:
Temperature resistance: 250 °C
 Double loop limit switch, used widely 
solid cast aluminum shell
 High mechanical strength
 Resistant to oil, water & pressure
 Due to the position indicator panel, it is easy to maintain
 Due to multiple actuators, its convenient to use.
 Mechanical life is long due to the design of double reed.
