Snap action, limit switches have many applications in industrial and consumer settings. These include applications such as temperature control, motor protection, and actuation of machinery. The ESE-13H05B is a popular limit switch and its applications and functioning are as follows:

Applications

The ESE-13H05B is suitable for circuits requiring reliable limit switch action, including on/off control, rate-of-rise control, or position sensing that requires an external force or momentary pressure. It is suited for the following applications:

• Tractor trailer load monitoring
• Material handling equipment
• AC/DC motor control
• Electronic weighing scales
• Air compressor/pump controls

Working Principle

The ESE-13H05B works in two stages - a switch actuation period followed by a switch release period. When the setpoint is reached, the internal spring mechanism is actuated, which causes a precise displacement of the contact element. This displacement of the contact element is detected by the internal electrical control circuit, which triggers a signal to the external circuit to provide an output. When the switch actuation begins, a non-volatile storage element is turned on to ensure the output signal is steady.

The switch then enters the second stage - switch release. When the setpoint is no longer reached, the spring will release the contact element and return it to the original position. The internal electrical control circuit will detect this change and will switch off the non-volatile storage element, resulting in the output signal becoming steady again. Therefore, the circuit can control the output current accurately, allowing it to control various functionalities.

Durability

The ESE-13H05B has undergone rigorous testing and meets some of the most stringent safety standards for limit switch devices. Additionally, it features a dustproof, waterproof, and fire-resistant housing, ensuring it can last through normal wear and tear. The switch also features wear and fatigue resistant movable contact points, ensuring longer operational life.

Conclusion

The ESE-13H05B is a reliable, durable limit switch with a wide array of applications. It works with a two-stage mechanism, ensuring the output current is accurately controllable and that the desired functionality is achieved. The dustproof, waterproof, and fire-resistant housing provides additional protection for the device, making it a reliable, safe choice for any application.
