Rotary Gear Limit Switch Working Principle

Springer controls offers rotary limit switches with input ratios from 1 1 to 8100 1.

Rotary gear limit switch working principle.

They can be configured with up to 12 contacts for signaling and combined with other accessories like encoders and potentiometers to achieve your desired result. Custom input ratios are available on request. New limit switch fgr2 ex certified atex and iecex in aluminum and antistatic plastic case suitable for use in zone 2 gas and zone 21 dust. The actuator is the part of the switch which physically comes in contact with the target.

Electromechanical limit switches use arms levers knobs plungers or other actuators that make physical contact with another object. Rotary limit switches may use mechanical or solid state means to detect an object and switch a load. Most limit switches contain the following functional parts in one form or another. Limit switch working principle the limit switch is like a 1 no 1 nc push button.

Multi pole multi position rotary switches are mostly used to switch operating conditions. The working principle of the rotary switch is. Rotary limit switches rotary limit switches are electromechanical controls consisting of an input shaft gear reducer signal transmitter and limit or safety switches. Change the resistance value within a range and then there is a contact switch.

Drive mechanisms are classified into three types as shown in the following figure. The push button is actuated by hand whereas the limit switch is operated mechanically. The main function of the limit switch is to open or close an electric circuit when the physical limit of the operation of the controlled device has reached. If desired encoders resolvers power interfaces or potentiometers can also be integrated consult category position transducers for additional product information.

The device works through a gear transmission drives a cam system operates on 4 or 6 microswitches that after a certain number of revolutions predispose the engine or equipment at startup or at the stop. Single pole single position rotary switches are often used together with rotary potentiometers in operation.
