BE-2RB-A4

Snap Action, Limit Switches – BE-2RB-A4 Application Field and Working Principle

The BE-2RB-A4 is a versatile snap action, limit switch. This type of limit switch is used in a variety of industries as an effective way of controlling movement or regulating pressure. It is one of the most commonly used types of switches, used for basic functions like turning on and off circuits, controlling devices, and setting limits on systems. It offers a secure solution to many industrial needs.

Application Field

The BE-2RB-A4 is especially well suited for applications in the automotive and manufacturing industries. It can be used for controlling a variety of functions including engine fuel supply, motor speed, transmission control and preventing overloads in assembly lines. It is also commonly used in commercial applications such as vending machines, bank machines, and cash registers. Additionally, it can be used in security systems and factory automation.

Working Principle

The BE-2RB-A4 is a snap-action, limit switch, meaning it works by quickly opening and closing an electrical circuit when a predetermined limit is reached. It does this by sensing whether a physical or magnetic force is applied to the actuating arm. When the force is detected, the contacts are closed and power is supplied to the circuit, activating the connected device. When the force is removed, the contacts are opened, turning the device off.

As a safety feature, the BE-2RB-A4 has three positions – normally open, normally closed, and maintained. If a normally open is used, the device will remain open until it is manually closed by applying a force to the actuating arm. The normally closed position works in the opposite way, remaining closed until a force is applied. The maintained position allows the circuit to remain open or closed, even after the force is removed.

Conclusion

The BE-2RB-A4 snap action, limit switch is an effective and secure solution for a variety of industrial applications. Its three-position feature gives it great versatility for controlling motors and other devices, as well as preventing overloads and ensuring safety in commercial applications. As such, it is an incredibly valuable tool for many industries.
