Overview

Essential details：CR215GFE LIMIT SWITCH HEAD GE

In electrical control system, limit switch is used to detect sequence control, position control and position state. Stroke and limit protection for operating machine equipment.

Limit switches, also known as travel switches, can be installed on relatively stationary objects (such as fixed frames, door frames, etc., or moving objects (such as cars, doors, etc.) referred to as animals). When the animal approaches the still life, the connecting rod of the switch drives the contact of the switch, which closes or disconnects the closing contact. Circuits and motors are controlled by changes in the connection and disconnection states of switching contacts.

In the actual production process, the limit switch should be installed in a pre-arranged place. When the module installed on the moving parts of the production machinery encounters the travel switch, the contacts of the limit switch move, thus enabling the switching of the circuit. Therefore, a travel switch is an appliance that switches circuits according to the travel position of moving parts, which works like a button.

Limit switch application
Limit switch is used in various types of machine tools and lifting machinery to control its travel and protect the terminal limit. The limit switch is used to control the speed of opening and closing of the door in the elevator control circuit, the limit of the automatic door and the protection of the upper and lower limits of the car.

The contact type of limit switch is more intuitive. On moving parts of mechanical equipment, limit switches are installed, limit blocks are set at fixed points of relative motion, or opposite mounting positions are installed. When the mechanical contact point of the travel switch touches the stop point, the control circuit is cut off (or changed) and the machine stops or changes its operation. Due to mechanical inertia, this travel switch has a certain “over range” protection switch from damage. Contactless comes in many forms, such as reed switches, photoelectric and inductors, and can be seen at higher levels in elevators.
