Snap action, limit switches form an important part in electrical circuits and systems. The 1DM418, which is a microprocessor-controlled limit switch, is an ideal solution for applications when reliable switch action is required. It has a wide range of applications, including process and machine control, detection of open-closed states, speed and position measurements, and many more. In this article, we will take a look at the applications and working principle of the 1DM418.

Introduction to the 1DM418

The 1DM418 is a limit switch with a single-pole, snap-action switch that is microprocessor-controlled. It is designed with a two-terminal, split poles mounted on a base that is riveted and insulated with TPE and epoxy-filled insulation. This switches provides accurate and fast response for the detecting of limit conditions, especially for switching of low-level signals. The switch has a long service life and is virtually maintenance-free. It is suitable for both normally open and normally closed applications, and is available in three different forms- standard, self-locking, and reversible. The switch utilizes a rocker arm with a laminated steel blade for increased durability and reliability.

Applications of the 1DM418

The 1DM418 has a variety of applications. It can be used in process and machine control, speed and position measurements, and as a reliable switch action device in industrial automation. It is an ideal switch for detecting open-closed states as well as low-level signals. The 1DM418 is also useful for detecting the presence and absence of objects in production lines, as well as for providing feedback on the progress of the production process. In addition, it can be used to detect and prevent damage to machinery caused by mechanical wear and tear. It is suitable for both dry and wet conditions, and can handle temperatures ranging from -30°C to +120°C.

Working Principle of the 1DM418

The 1DM418 utilizes a snap-action switching mechanism. This mechanism consists of a rocker arm and a contact bridge which moves when the button is pressed down. When the button is pressed, the electrical contact of the switch closes, and when it is released, the contact opens. The switch is also provided with a reset button which allows the switch to return to its original position even after the switch has been operated. The bridge is activated by an internal microprocessor that processes the signals from the push button and the surrounding environment (such as temperature, atmospheric pressure, etc.). This ensures that the switch responds quickly and accurately to the limit conditions it is designed to detect.

Conclusion

The 1DM418 is a highly reliable microprocessor-controlled limit switch that offers a wide range of applications. It is ideal for process and machine control, detecting open-closed states, speed and position measurements, and many other applications. The 1DM418 utilizes a snap-action switching mechanism which provides reliable switch action and a long service life with minimal maintenance. It is a suitable switch for both dry and wet conditions and can handle temperatures ranging from -30°C to +120°C. Overall, the 1DM418 is an excellent choice for industrial automation and production line applications.
