This article will discuss the applications and working principal of the D4A-1E05N switch in detail.

Applications

The Omron D4A-1E05N switch is mainly used for controlling electric motors, and as such can be found in a variety of industrial settings. It is commonly used for remote control mechanisms such as winches, hoists, and conveyors, but can also be used to operate agricultural and industrial equipment. Its compact size and versatility make it a popular choice for controlling electric motors in a variety of settings, including motor-driven machines, robots, and material handling applications.

This switch is also suitable for use in stationary applications, such as those found in automated assembly lines, where its superior repeatability is of great importance. Additionally, the switch is suitable for a variety of harsh environments, thanks to its electrical and mechanical features, such as its robust, corrosion-resistant construction and its IP67 protection classification.

Working Principle

The D4A-1E05N switch utilizes a snap action mechanism to perform its function. This mechanism is composed of two or more parts that come into contact with each other when the switch is triggered. The switch is actuated by an electric current passing through a coil, which moves the contacts into the open/closed position.

In order for the switch to remain in its tripped position, the actuating current is maintained, allowing for precise operation. The contacts of the switch will return to the open position when the actuating current is removed. This ensures that the switch will not remain in the tripped position if electric current is cut off, preventing potential accidental damage.

The switch also features a spring loaded design, which ensures that the activation force applied to the switch is not too high, enabling precise and repeatable operation. Additionally, it features a wide operating temperature range and a long service life of up to one million operations. Its fast switching time of just 10ms makes it ideal for applications requiring quick response times.

Conclusion

The Omron D4A-1E05N is a versatile and reliable snap action limit switch that is suitable for a variety of industrial applications. Its compact size and robust build make it suitable for mobile and stationary applications, and its superior repeatability is well suited for automated operations. Its fast switching time and long service life make it a reliable and affordable choice for controlling electric motors in a variety of settings. This switch is the perfect tool for a variety of engineering and industrial applications.
