D4N-412G

Snap action limit switches, such as the D4N-412G, are electromechanical devices that open or close an electric circuit in response to an external physical force. They are used in a multitude of applications, from monitoring industrial processes to controlling factory automation. In this article, we will discuss the application fields and working principle of the D4N-412G.

The D4N-412G is a snap action limit switch. It is designed for use in industrial and commercial applications, such as monitoring floor conveyors, detecting the presence of product on an assembly line, controlling motor starters, and signaling the operation of motor driven equipment. It is also suitable for use as a safety switch in hazardous environments.

The D4N-412G is made of stainless steel and is hermetically sealed to protect it from dust, moisture, and other environmental elements. It is rated up to IP67 and operating temperature range of -25°C to +65°C. It has a silver alloy contact rating of 20VAC and 15VDC at 1A and 250Vac at 0.5A. It is equipped with a long-life solenoid rated up to 2 million cycles.

The D4N-412G works on the principle of a snap action switch. It uses a compressed spring to hold the contacts in the open position and an actuator to close the contacts. As the actuator moves, it compresses the spring and eventually reaches a point where the spring can no longer keep the contacts open. At this point, the contacts snap shut, and the switch is considered to be "closed". Repeated movement of the actuator will cause the contacts to open and close in response to the force applied to the actuator.

One key aspect of the D4N-412G is its adjustable setpoint. This allows the user to adjust the force required to close the contacts on the switch. This allows the switch to be configured for a range of applications, from fine adjustments to heavy-duty applications. This also helps to prevent false trips and prolongs the life of the switch.

The D4N-412G is an ideal choice for a wide range of applications due to its high durability and reliable operation. It is an affordable option that provides a long operating life, making it an excellent choice for industrial and commercial applications. With its adjustable setpoint and high IP rating, it is an excellent choice for any application that requires a reliable and durable switch.
