E51-50B Application Field and Working Principle

The E51-50B snap action limit switch is a versatile, reliable and durable device used in industrial settings to switch circuits on and off based on physical movement. It is often used to detect the position of an object, detect an obstruction, or measure the speed of a moving object. The switch features adjustable action, adjustable release angle, thermoplastic construction and extended switching cycles.

The E51-50B snap action limit switch is designed for use in a variety of applications involving the switching of electrical circuits on and off. It is particularly useful for applications where a fast and reliable response is required to detect the position of an object or to measure the speed of a moving object. Examples of applications include systems requiring the detection of an obstruction, the adjustment of a conveyor belt, and the measurement of the speed of a fan.

Working Principle

The E51-50B snap action limit switch works by sensing the physical movement of an object or machine. This is accomplished through the use of two contact points. When the two contact points touch one another, the electrical circuit is closed. When the two contact points move away from one another, the electrical circuit is opened. The adjustable action allows for the contact points to open or close depending on the direction of the movement of the object or machine.

The switch also features adjustable release angle. This feature allows for added flexibility in the operation of the switch by allowing the user to select the maximum amount of angle by which the contacts will open or close as a result of the movement. The thermoplastic construction ensures that the switch is able to remain durable and reliable even in harsh environments.

Finally, the extended switching cycles feature ensures that the switch can operate accurately and reliably for long periods of time. This is particularly useful for applications where the switch must remain operational for long periods of time, such as conveyor Belt applications, or systems requiring the detection of an obstruction.
