Snap Action, Limit Switches are commonly used in the automation industry to monitor or limit certain conditions or parameters within a machine. The D4N-6D72R is one such Snap Action, Limit Switch which has a variety of applications and a unique working principle.

The D4N-6D72R is a Sub-Miniature limit switch which has a choice of 3 actuators and a range of operating temperature ratings. The Actuator can be chosen from the ranges of Single Circular Roller, Lever Arm and a Push Button unit. It is rated at 12A and 250vac, either single pole (standard) or double pole (switch on either side of the contact block). This Limit Switch is ideal for use in automation applications where compactness and reliability are paramount.

The application fields of the D4N-6D72R limit switch encompass a wide range of industries. Its compact size and versatile design mean that it can be used in electrical control systems such as detection of opening/closing of doors or machines, and position sensing. Because of its robust construction it can be used in automated factories, vending machines and ticket dispensers, and its fanless design offers it protection from dust particles in harsh environments.

The working principle of the D4N-6D72R is based on the use of an Actuator that exerts an amount of force on the terminal and contact block which helps close the circuit when operated. When the terminal and contact block have a power run through them, the normally open circuit is then closed. The switch can then be reset by disengaging the Actuator from the terminal and contact block and the circuit reverts back to its open state. This type of switch concept can be used in a variety of applications and is often implemented in conjunction with an electric switch for added safety for the user.

In conclusion, the D4N-6D72R Limit Switch is a reliable and versatile Snap Action Switch, capable of being used in a wide range of applications. Its working principle is based on a simple contact, normally open design with an Actuator which is used to close the circuit. This switch offers excellent reliability and is often used in combination with an electric switch in automated systems to ensure user safety.
