D4N-8C22

Snap action, limit switches are perfect devices for automation, control and monitoring applications. The D4N-8C22 is a snap action, limit switch developed by Omron, featuring a top-of-the-line design and construction which ensures reliable and long-lasting service and performance in the field. So, what is the application field and working principle of the D4N-8C22?

Application Field

The D4N-8C22 is suitable for use in a variety of automation, control, and monitoring applications. It can be used in any application where controlling of the operating environment is required, such as industrial automation, HVAC systems, computer systems, power generation and transmission, and oil and gas processing. It is also suitable for applications in laboratory equipment, transportation systems, water treatment, and process control.

Working Principle

The D4N-8C22 is a top-of-the-line snap action, limit switch which utilizes a bimetallic spring element. This element is made up of a pair of metal strips that are joined together at one end. When a preset temperature is reached, the metal strips expand, creating tension in the spring that causes the contact to move. When the temperature drops, the metal strips contract and the spring returns to its original position, reversing the contact’s motion.

The contacts are enclosed in a durable, waterproof housing which prevents environmental contaminants from impacting the internal components. The unit is also corrosion resistant and helps to ensure reliable operation in a variety of hazardous environments. In addition, the D4N-8C22 can be installed in any “N” size snap action switch enclosure, making it a great choice for applications that require a compact limit switch with precision performance.

Conclusion

The D4N-8C22 is a reliable and durable snap action, limit switch that is suitable for use in a variety of automation, control, and monitoring applications. Its top-of-the-line design and construction ensures reliable performance in even the harshest environments. In addition, its small size and corrosion-resistant housing make it an ideal choice for precision performance in tight spaces.
