21EN262-6 Application Field and Working Principle

The 21EN262-6 is a snap action, limit switch designed to detect the opening and closing of doors, windows, and other similar applications. This switch utilizes a sensitive, proximity sensing system to detect the actuation of a moving object, such as a door or window, when it passes close to the switch body. The switch\'s proximity sensing system allows the switch to detect the opening and closing of a door or window without the need for physical contact.

The working principle of this switch is rather simple. The switch body includes an interior coil, generating a continuous magnetic field. This magnetic field is monitored by a microcontroller using Hall Effect sensors. When an object, such as a door or window, moves close enough to the switch body, it disrupts the magnetic field. The sensor-based system then sends an electrical signal indicating the presence or absence of the object, thereby triggering the switch.

The 21EN262-6 is suitable for applications where a reliable and long-lasting switch is required, such as in industrial settings, entrances, and exits. The switch is rated for up to 1 million operations and can be used in temperatures between -10 and +50 degrees Celsius. The switch is also rated IP54 and is therefore resistant to dust and water, making it ideal for use in outdoor environments.

The 21EN262-6 is a reliable and versatile snap action, limit switch, making it an excellent choice for a wide range of applications. Its proximity sensing system allows it to detect the presence or absence of a door or window without the need for physical contact, and its resistance to dust and water make it suitable for use in outdoor environments. The switch is rated for up to 1 million operations, and its operation temperature range ensures proper functioning in most environments.
