Snap action switches and limit switches are widely used for a variety of applications that require consistent and reliable operations. The D4N-212G is a snap action, limit switch from Omron that is specially designed to provide reliable best-in-class operation in industrial environments. It is an ideal choice for applications that require high performance, accuracy, and durability.

Application Fields of D4N-212G

The D4N-212G snap action switch is most commonly used in industrial automation applications, such as, industrial machinery, conveyors, packaging systems and other industrial control systems. The device can be used as an electromechanical actuator that is suited for controlling lifting, sorting and positioning applications. Moreover, the switch is also deployed in bulk material handling systems, security systems and access control systems. Its long life expectancy of up to 10 million operations makes it an ideal choice for applications involving high frequency manual operation.

Working Principles of D4N-212G

The D4N-212G is a micro switch that uses a snap action mechanism for triggering. The switch is made up of two metal arms that open and close when the external force is applied. The arms are connected to a spring-loaded actuator, which is set to a specific level of resistance. When the switch is actuated, the spring-loaded actuator is pushed outwards, causing the two metal arms to close. This triggers the switch and activates the circuit connected to it.

The switch can also be activated when an external force is applied in the opposite direction. When the force is removed, the spring-loaded actuator returns to the initial position. Thus the circuit is open, and the switch remains in its “off” state.

The maximum limit switch rating of the D4N-212G snap action switch is up to 1.5A at 250 VAC. It is equipped with C/O (Change Over) contacts that ensure accurate and reliable switching operations in a wide range of applications. The switch has an IP65 ingress protection rating, which ensures that it is dust-proof and water-resistant.

Conclusion

The D4N-212G from Omron is a snap action, limit switch that is designed to provide reliable operations in a wide range of industrial applications. It uses a snap action mechanism for triggering and is equipped with C/O (Change Over) contacts for accurate switching operations. The device has a long life expectancy of up to 10 million operations and an IP65 ingress protection rating.
