Product Description

Heat stroke switch NHG1

High temperature resistant switch inside 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 without oxidation or pollution and lead to damage. In order to meet customer demand for high temperature, high temperature switch, I have developed a series of NHG series high temperature switch, NHG series high temperature travel switch maximum temperature of 550 degrees, 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.

NHG1 high temperature switch for cylindrical type, through the impact of high temperature switch of the cylinder type, so that the high temperature of the trip switch cylinder to move down, so that the switch of the contact action and achieve the switch, so as to achieve the purpose of the collision switch.

 Open hole size and outline dimension  :





The highest temperature environment 550 degree double loop type limit switch, a wide range of uses with strong one casting aluminum alloy shell, high mechanical strength with oil resistant, waterproof and anti pressure structure with setting position is installed in the dashboard, so it is easy to maintain many kinds of actuator, the easy to use built-in contacts a double spring design, mechanical life long

Heat stroke switch - note.

Heat stroke switch in use should pay attention to the problem (1) in the installation of high temperature travel switch, to check whether the iron in the walking in place of the impact of travel switch head, must not be a collision in the middle or other parts of the trip switch. (2) in the installation or in were examined for resistance to high temperature trip switch to fix it firmly, and with slide hand or dynamic pressure high temperature limit switch action head, listen carefully, check whether there is the sound of "bang", if there is no should be open resistance to high temperature limit switch, regulation connecting the micro switch and the movement axis of the screw.
