Snap Action, Limit Switches

Snap action, limit switches areelectromechanical devices that are used to detect the presence or absence of an object. They are used inmany industrial applications where control over the movements of an object is required. Snap action, limit switches can also be used in hazardous areas, where a proximate switch cannot be used due to safety considerations.

83894121 Application Field and Working Principle

Snap action, limit switches areused in various industrial applications, including automated assembly machines, agricultural equipment, and process control applications. Their fundamental working principle is based on the principle of contact closure. When the actuator contacts the surface of themoving object, it forces the contact points of the switch to close and make an electrical circuit. This action operating element is known as snap action. When the actuator’s arm is raised again (action opening), the contacts of the circuit open, and the electrical circuit is broken.

The 83894121 snap action, limit switch is designed to detect the position of a moving machine element or a contact surface on the switching surface of a workpiece. The two contact points are situated in a slidable plastic case. When the actuator is in contact with the workpiece, the two contact points touch and make the circuit. When the actuator is lifted, the two contact points are separated and the circuit is broken.

The 83894121 snap action, limit switch can be used for more than one purpose, such as for simple manual operation of a machine, for cable reel operation, and for control of a threaded plate. Its compact size is convenient for applications where space is limited. Its features include an adjustable range from 0.5 to 90 degrees, with a range of 0.1 to 15 mm for contact spacing, and a resolution up to 0.01mm for contact spacing. The rated protection of the switch is IP67.

The 83894121 snap action, limit switch works with industrial actuators, such as solenoids, solenoid valves, and actuator motors, to provide precise control over a machine’s movements. Its durable construction and compact size make it an ideal switch for almost any industrial environment.

In conclusion, the 83894121 snap action, limit switch is an economical and reliable electromechanical device that has been designed to detect and control the positions of a moving machine element or a contact surface. It has a range of adjustable settings and an IP67 rating, making it an ideal switch for a variety of industrial applications and hazardous areas.
