D4C-3420

D4C-3420 is a special visual switch widely used in industrial automation system, and it belongs to the snap action limit switches.

Features and Benefits

• High repeat accuracy
• Versatility due to excellent operating characteristics
• Long working life
• Robust and reliable

Application Field

D4C-3420 snap action limit switches are commonly used in a wide range of industries, such as in printing machines, car production lines, and production process control. They are very suitable for the measurement and control of reciprocating movements in machines and processes. The limit switches feature a pronounced snap-action effect, which makes them highly reliable for detecting steady and unstable positions, even against longitudinal loads.

Working Principle

The snap action limit switch D4C-3420 developed by Automation Solutions is a kind of limit switch with visual double integrated structure, which is widely used in industrial automation field. The main structure consists of two parts, one is the mechanical part and the other is the electronic part, which are equipped with a special limit motor for driving.

The working principle is quite simple and intuitive. The limit motor is responsible for setting the working range, which is controlled by the control circuit. When the limit motor has reached its limit, it triggers the switch inside the limit switch and sends the limit signal to the control circuit. Meanwhile, the mechanical part will activate the snap action effect due to the elastic force of the spring and make the arm re-positioned.

The advantage of this structure lies in the repeat accuracy and its ability to withstand external loads and impacts. This structure is also applicable to long-distance, long-term direction and length measurement and position control.

In a nutshell, the working principle of D4C-3420 limit switches can be summarized in two words: to control the mechanical part with electronic parts.
