Introduction to 22SM401

The 22SM401 is a type of snap action, limit switch. It is one of the most popular limit switches out there today, and it has a wide range of applications due to its ability to perform reliable, repeatable and consistent switching operations at exceptionally high magnification levels. In short, the 22SM401 is a reliable and effective limit switch option for many industrial applications.

Application Fields

The 22SM401 snap action, limit switch is most commonly used in industrial automation and motion control, particularly in the areas of position and speed control. It has emerged as one of the most reliable and trusted limit switch varieties available and is widely used in devices such as cranes, conveyors, hoists, elevators and overhead door mechanisms. In addition, its robust design and top-notch switching action makes it perfect for applications where high speed accuracy is required, such as for automatic sorting systems, positioning assemblies and automated assembly lines.

Working Principle

The 22SM401 snap action, limit switch works on a simple principle. It is designed to “snap” open and close at pre-defined distances, allowing for reliability and precision within its operational range. The mechanics of this are relatively simple, as the switch contains internal activated levers or trip springs that are arranged in pairs or quadruplets. When the switch is engaged and a predetermined trip point is reached, it causes the levers/trip springs to open or close as appropriate. This causes the contacts within the switch to open or close as necessary, providing reliable and effective operation.

Features and Benefits

The unique design of the 22SM401 gives it a number of features and benefits over other, comparable limit switches. For example, it stands out due to its high speed accuracy and accuracy over a wide range of operations. It is this feature that makes it perfect for automated sorting systems, positioning assemblies and automated assembly lines. In addition, the 22SM401 limit switch is designed for over 1 million operations and has a remarkably fast response time (where a trip point is reached in as little as 0.03 milliseconds). Also, the switch has a wide operating temperature range and is designed to resist dust and liquids. Finally, the switch is durable and relatively easy to install, making it a popular choice for many applications.

Conclusion

The 22SM401 snap action, limit switch is an incredibly reliable and effective limit switch option. It is well-suited for applications in industrial automation and motion control, such as cranes, conveyors and hoists, and is a particularly popular choice for applications where high speed accuracy is required. Its unique design features and benefits, such as its high speed accuracy, dust and liquid-resistant design, wide operating temperature range and 1 million operation life span make it perfect for a variety of industrial applications.
