Snap action, limit switches are highly versatile electrical switches favored for their longevity, simplicity, and accuracy. In particular, the D4E-1B21N model offers a wide range of applications and is extremely reliable. Here, we\'ll discuss the working principle and application field of this switch.
Application Field
The D4E-1B21N model is perfect for high temperature and harsh environment. It is equipped with a variety of features that make it ideal for these types of conditions, including dust-resistant and IP67 rated housing, as well as self-cleaning contacts and long mechanical life. Suitable applications include automotive, machine tools, vending machines, air conditioning and many more.
Working Principle
The working principle of the D4E-1B21N switch is premised on the reliable snap-in and snap-out action of its contact system. The switch\'s contacts are designed to break their electrical connection when a certain pressure is applied. This pressure is generated by the mechanical properties of the switch itself, which uses a central spring for reliable operation. As the switch is activated, the contact system will move in and out from its mechanical setting position, thus successfully closing or opening the electrical circuit.
Realiability and Safety
In addition to its high temperature and harsh environment applications, the D4E-1B21N switch is also extremely accurate and reliable. This is because it is equipped with a fail-proof zero-speed monitor and double-break contact system. This means that it can detect even the smallest current fluctuations, making it suitable for applications that require extreme accuracy and reliability. Furthermore, it also enhances safety, as it can immediately detect any impending fault due to its double-break contact system.
Conclusion
The D4E-1B21N switch is a reliable and versatile device that makes it ideal for a wide range of application fields. Its contact system is designed to operate at a certain pressure, and its double-break contact system ensures accuracy and reliability, as well as enhanced safety. It is also highly suitable for high temperature and harsh environment applications, making it the perfect choice for many industrial applications.
