Snap action, limit switches, such as GKRA40MXA2-F05, are widely used in various fields as intelligent sensors, actuators and operational control elements. With its rapid response, reliable performance and convenient installation, it has become an important part of automation application. This article will introduce the application field and working principle of GKRA40MXA2-F05.

Application Field

GKRA40MXA2-F05 limit switch is mainly used in equipment with a control switch and control unit, including power industry, metallurgical industry, petrochemical industry, instrumentation industry, mining industry, aviation and aerospace industry, military industry, energy industry and so on. Unlike regular switches which make one circuit on or off at a time, this kind of limit switch can detect the position of the mechanical components in a very short time, making it suitable for repeat positioning and long-term use occasions.

In power industry, GKRA40MXA2-F05 can detect high-voltage switchgear position, such as upper and lower contact switch, blade switch and disconnector, in order to control the operation of power system. In metallurgical industry, it is used to detect the open and close position of coke oven door so as to know the open and close status of coke oven and to adjust the production flow accordingly. In aviation and aerospace industry, this limit switch can detect rocket launch position, wing flap angle and so on.

Working principle

The GKRA40MXA2-F05 limit switch is composed of a switch button body, a spring and a head core. The switch body is equipped with a plunger and a micro switch. When a mechanical device is running, the switch body is moved, and the plunger forward presses the spring installed in the switch body, so the power can drive the head core through spring force, contact the snap-action micro switch in the switch body and generate corresponding electrical signal output.

The advantage of GKRA40MXA2-F05 limit switch lies in its fast response, low temperature rise and long service life. Once given a certain action, the switch can respond in less than 0.3 minutes, with an accuracy of 0.05mm and a service life of 2 million times. Therefore, it is very suitable for precise position control and precise repeat positioning application. Of course, it also has great anti-interference and dust-proof performance, making it more suitable for harsh industrial environments.

Conclusion

GKRA40MXA2-F05 limit switch is widely used in various fields as intelligent sensors, actuators and operational control elements. Its fast response, reliable performance and convenient installation make it suitable for precise position control and precise repeat positioning application. In conclusion, this limit switch is an important part of automation application.
