AH745379-A

Snap action limit switches are employed as monitoring and controlling devices, offering reliable and repeatable performance when opened or closed. The AH745379-A snap action limit switch by TE Connectivity is widely used for many applications, with its high performance and long lasting working life. It offers a variety of features such as direct usage as a replacement for electromechanical switches, extended versus mechanical life ranges, durable construction and a high reliability rating. In this article, we will discuss the application field and working principle of the AH745379-A limit switch.

Applications of the AH745379-A Limit Switch

The AH745379-A limit switch is widely used in a range of industrial applications, such as air conditioning systems, machine tools, water treatment facilities, medical devices, automotive and transportation, food/beverage processing, and robotic arms. In these applications, it serves to provide reliable performance, quick response time and extended life cycles. For example, in the case of an automotive application, the AH745379-A could be used to control and monitor engine systems, lighting, or airbags. Similarly, in the food/beverage industry, the device can be used to detect temperature and moisture levels and alert personnel when food safety standards are not met.

Working Principle of the AH745379-A Limit Switch

The AH745379-A limit switch operates by means of a mechanical spring. When either the capacitive or mechanical input force applied to the actuator is greater than that of the spring, the contact points open. This causes an electrical circuit to be broken, signaling that the device reached the specified limit. Similarly, when the force applied to the actuator is reduced, the contact points close, creating an electrical circuit and signaling that the limit has been passed. This snap action action allows the AH745379-A to serve as a reliable switch with an extended life cycle.

Aside from the snap action design, there are other features within the AH745379-A which further improve its performance. The device is encased in a rugged housing, which helps to protect the metal components from environmental conditions and fluids. Additionally, the device includes EMC compatibility, ensuring that the switch will perform properly even in extreme electrical interference.

Conclusion

The AH745379-A snap action limit switch is a reliable and high performing device, used for a wide array of industrial applications. It utilizes a mechanical spring to snap open and close contact points, signalling that either a specified limit has been reached or passed. Additionally, the device provides a rugged housing and EMC compliance, helping to extend its life span. Thanks to these features, the AH745379-A is quickly becoming a go-to monitoring and control device for many industrial applications.
