Snap action, limit switches are devices used to control, detect and monitor the operation and movements of various machines, including elevators, escalators, and conveyors. BA-2RB are universal limit switches, designed as three-pole units with a robust body, with gold-plated contacts, NEMA 4/IP67 enclosures, and self-aligning changeover contacts for long life. They’re ideal for safety applications, such as machine shut-off and chain control.

BA-2RB limit switches are available in multiple configurations and contact materials, along with a selection of actuator styles and operating heads. They’re suitable for an array of applications, from photocopier safety to industrial oven control and conveyor belt motion. Compared to competitors, their design and construction provide higher levels of durability, longer life span, and greater corrosion protection.

The BA-2RB limit switch’s working principle is based on a simple off-on action: when the lever arm is pushed, the contacts open, and when the lever arm returns to its original position, the contacts close. The device is activated either manually or automatically when the limit switch’s plunger is struck by a surface or object. This causes the contacts to open or close, depending on the set limits.

The BA-2RB limit switch has a few important features that make it suitable for a wide range of applications. For instance, it has a rugged body construction, with external features designed to protect against dust, water, corrosive materials, and other contaminants. It also has silver contacts, which are adjustable from 0.004” to 0.025” and provide reliable electrical performance in most environments.

In addition to its external features, the BA-2RB limit switch has self-aligning contacts, which allow for optimum performance with minimal maintenance. The compact design also means fewer components, reducing the chances of failure due to mechanical wear and tear. On top of that, the device has an adjustable pivot point that increases the throw distance and makes the switch more responsive.

The BA-2RB limit switch is used in a variety of applications, from industrial ovens to elevator control. It’s commonly used to detect the presence of objects and detect when specific conditions or processes have been met. For instance, it can be used to limit a conveyor belt’s speed, or to prevent the acceleration of an escalator. In photoelectric applications, the BA-2RB limit switch can be used to detect the presence of an object and shut off the power when it has been detected.

Overall, the BA-2RB limit switch is a versatile, reliable, and robust switch, suitable for many applications. It provides enhanced protection from environmental contaminants and wear and tear, while its self-alignment features make it more responsive and reduce the need for maintenance. Its adjustable pivot also enables greater throw distances and higher levels of sensitivity, making it an ideal choice for many applications.
