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.

Rotary gear limit switch working principle.

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. Electromechanical limit switches use arms levers knobs plungers or other actuators that make physical contact with another object. Most limit switches contain the following functional parts in one form or another. Change the resistance value within a range and then there is a contact switch.

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. Springer controls offers rotary limit switches with input ratios from 1 1 to 8100 1. This is the switch. Structures and principles drive mechanism of limit switch the drive mechanism of the limit switch is an important part of the limit switch and is directly linked to seal performance and operating characteristics.

The push button is actuated by hand whereas the limit switch is operated mechanically. Drive mechanisms are classified into three types as shown in the following figure. Rotary limit switches rotary limit switches are electromechanical controls consisting of an input shaft gear reducer signal transmitter and limit or safety switches. Limit switch working principle the limit switch is like a 1 no 1 nc push button.

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 working principle of the rotary switch is. The actuator is the part of the switch which physically comes in contact with the target. Multi pole multi position rotary switches are mostly used to switch operating conditions.

Custom input ratios are available on request. If desired encoders resolvers power interfaces or potentiometers can also be integrated consult category position transducers for additional product information.
