4HS143-120

Snap action, limit switches are specialty switches that are used in a variety of applications, ranging from industrial machinery to medical equipment. The 4HS143-120 is such a switch that is used in a wide variety of applications. In this article, we will discuss the application field and working principle of the 4HS143-120.

Application Field

The 4HS143-120 is a snap action, limit switch specifically designed for industrial applications. The switch has a number of features that make it suitable for use in the industrial environment. These features include the ability to operate in a wide variety of temperatures, the ability to handle a range of voltages, and the ability to handle up to 125A current.

The 4HS143-120 can be used in a variety of industrial applications, such as furnaces, car doors, hydraulic presses, conveyor systems, and ovens. As the switch can handle a range of voltages, it can be used in both AC and DC applications. The switch can also be used in safety circuits that require reliable operation and are subject to extreme temperatures.

The 4HS143-120 has been designed for ease of use. It has a simple push rail design that allows for easy installation, and the tension of the actuator can be easily adjusted to suit the application.

Working Principle

The 4HS143-120 is a snap action limit switch. It is designed to operate in a specific way when the switch is activated. When the switch is deactivated, the contact points are open. The contacts become closed when an external force, such as an actuator, contacts the switch. This contact causes the contacts to move and close, thus creating an electrical connection.

The gap between the contacts closure is adjustable, allowing the switch to be used in a number of applications. The switch is designed to open the contact points on its own when the external force is removed, thus preventing any further connection. This is known as the “snap-action” of the switch.

The 4HS143-120 is designed for reliability and a long service life. The switch is made from durable materials and is designed to withstand a range of temperatures, voltages, and current that could be encountered in industrial and other applications.

Conclusion

The 4HS143-120 is a snap action, limit switch specifically designed for industrial applications. The switch is designed for reliability and a long service life, and it can handle a range of temperatures and voltages. The 4HS143-120 is easy to install and can be used in a variety of applications, such as furnaces, car doors, conveyor systems, and ovens.
