Snap action limit switches are an integral part of many industrial automation systems. The 1EN75-R3 is a rugged snap action switch that is used in a variety of environments. In this article, we will look at the 1EN75-R3’s application field and workings principles.

What Is a Snap Action Limit Switch?

A snap action limit switch is an electromechanical device that performs a simple on-off switching action when a pressure, thermal, or magnetic force is applied. It consists of a contact point and a mechanical actuating mechanism. When the contact point is activated by the external force, the mechanical actuating mechanism causes the switch to snap open, making contact between the contacts. This snap action ensures a reliable, quick response to any application.

Applications for 1EN75-R3

The 1EN75-R3 is suitable for many industrial and commercial applications such as opening and closing of factory doors, controlling of laboratory equipment, sensing of conveyor belts, activating of safety devices, and so on. The 1EN75-R3 offers two different connection options: one with screws and the other with a solder cup. The maximum operation current of this switch is 1A and its maximum operation voltage is 250VAC.

Working Principles of 1EN75-R3

The operation of the 1EN75-R3 is based on mechanical principles. The unit is equipped with a spring-loaded actuator, which is activated by an external force. When the actuator is compressed and released, the contacts of the switch snap open or close based on the direction of the force. This quick action ensures reliable operation and consistent contact performance. The 1EN75-R3 also features an adjustable head travel so that contact positions can be adjusted.

Conclusion

The 1EN75-R3 is a high-performance, reliable snap action limit switch suitable for a variety of industrial and commercial applications. It features a rugged housing and adjustable head travel. Its quick-action snap switch ensures reliable and consistent contact performance. This switch is an ideal choice for any application requiring a quick and reliable switching solution.
