Differential — distance (degrees) between contacts trip and contacts reset. Overtravel — movement of the actuator beyond the contacts trip point. Initial Position — position of actuator when no external force is ap-plied to the actuator.

Some other important terms associated with limit switches : Operating force ( torque) — force .

When an object comes into contact with the actuator, the device operates the contacts to make or break an electrical connection.

The purpose of this guide is to reinforce the basic aspects of. Recognize marketing opportunities. Develop solutions with related components. Make educated sales recommendations.

This article provides an overview of the various types of electrical limit switches commonly used in industrial applications. Limit switches are electro- mechanical devices. The contacts are mechanically linked to an actuator. Limit Switch are basic switches that have been encased to protect them from external forces, water, oil, and dirt.

Many models are available, such as those resistant to hea col or corrosion, as well as high-precision models.

General Purpose Limit Switches. Many contact arrangements are available as well as both slow and snap action contact operating mechanisms. This family of limit switches are available in four different body styles: mm metal, mm metal and plastic, and mm plastic. Switches are electrical devices used to break electrical circuits.

Mechanical limit switches use physical contact to detect the presence of an . Eaton limit switches offer reliable power circuit control for cranes, hoists, conveyors and similar types of moving machinery in an industrial environment.
