21EN382

Snap action, limit switches are some of the most common switches used in modern electrical and electronic systems. While these switches can be used for a variety of applications, the 21EN382 is especially well suited for use in applications requiring precision switching and reliable feedback.

What is the 21EN382?

The 21EN382 is a type of snap action limit switch. This switch is designed with a robust metal housing and utilizes a plunger-operated actuation. It features a positive contact system with crisp actuation and positive reliable repeatability. It offers highly accurate, precision switch ratings and a wide variety of switch settings. This type of switch is ideal for use in applications where precise switching and reliable feedback are required.

Application

The 21EN382 is commonly used in applications where accurate, reliable operation is required. Examples include in manufacturing processes where accurate switching needs to occur for continued operation; and in control panels, where actuation must be consistent and repetitive for efficient operation.

In quickly changing environments, where the switch must be able to tolerate externally applied forces and not cause misoperation, the 21EN382 is the switch of choice. The switch is also ideal for use in applications requiring hazardous area or dust-proof installation, as the 21EN382 is certified for both hazardous and dust-protected areas.

Working Principle

The 21EN382 operates by means of a plunger-operated actuation. This type of actuation is known as snap action, which involves rapid operation of the switch’s actuator. The switch utilizes a snap lever that is compressed against a rigid surface that is mounted on the switch\'s housing. As the snap lever is compressed, a spring element is released and the contacts move quickly to the desired position.

Once the switch is actuated, the contacts will remain in the desired position until it is manually reset. This ensures accurate and repeatable switching, making the 21EN382 ideal for applications where reliable feedback is needed. Additionally, the switch can operate up to 250 times per minute, making it suitable for applications requiring frequent or rapid switching.

Conclusion

The 21EN382 snap action limit switch is a reliable, highly accurate switch that is ideal for use in applications requiring precision switching and reliable feedback. Its robust metal housing and snap action components ensure reliable and repeatable operation, making it the perfect switch for hazardous and dust-protected environments. The switch is also rated for up to 250 operating cycles per minute, making it well suited for applications with frequent switching needs.
