Product Description

NHY1 high temperature travel switch details:

High temperature travel switch, high temperature position switch (also known as high temperature limit switch), is a commonly used small current main electrical appliances. High temperature travel switch is mainly used for AC 50HZ/60HZ, 380V, DC 220V and the following high temperature environment of the electrical line, for the movement mechanism of the stroke control, motion direction or speed of the transformation, automatic control of machine tools, motion control and control of movement mechanism or program. The contact action is realized by the collision of the moving parts of the production machinery to realize the control circuit and achieve the control purpose.

High temperature limit switch NHY1 handle roller arm type, through the collision trip handle roller arm, roller arm to the left or to the right swing, so as to make the switch contact action and realize the switching circuit. High temperature travel switch for metal aluminum alloy material, the internal use of high temperature resistant material cast into the full closed contact switch,a group of normally open a group of normally closed maximum allowable current 220V 5A/AC (other voltage acceptance), contact after special treatment can be used in high temperature environment for long time, and not oxidation or pollution, in order to improve the product in high temperature environment, especially in high temperature travel switch internal coating, increase its high temperature protection performance. NH series high temperature travel switch highest temperature is divided into 4 grades, 150 degrees, 250 degrees, 350 degrees, 550 degrees (ceramic), which can be divided into roller arm type, adjustable rod type, pressure plunger and roller pressure column type, etc. more than 10 kinds of specifications, can meet the requirements of different occasions. Widely used in electric power, chemical, petroleum, textile, steel and other industries.
 

Characteristics of high temperature travel switch:
Double circuit limit switch, a wide range of uses
Solid cast aluminum alloy housing
High mechanical strength
Oil resistant, waterproof and anti pressure structure
Because it is equipped with a position indicator plate, it is easy to maintain.
Actuator variety, easy to use
Inside contact seat has double reed, long mechanical life
Open hole size of high temperature travel switch:

Upper and lower hole distance:58.7 ±0.2 Left and right  hole distance:30.2±0.2

 Problems in the use of high temperature resistant travel switch: (1) in the installation of high temperature switch, to check whether the object in the travel in place of the collision of the travel switch head, the middle or other parts of the trip switch can not be collision. (2) in the installation or in were examined for resistance to high temperature trip switch, to put it firmly fixed, hand toggle bit resistant to high temperature limit switch head, listen carefully, check whether there is the sound of "bang", if not, please open resistance to high temperature limit switch, adjusting connects the inching switch and the action of an axis of the screw.
