D4N-2E22

The D4N-2E22 is a snap action limit switch designed to provide reliable and secure mechanical limit operation and is ideal for detecting status changes in a wide variety of applications. It offers reliable and cost-effective solutions for mechanical limit sensing with excellent repeatability. This switch is built with a traveling contact that trips when actuated, helping safeguard against false readings and premature failure.

The D4N-2E22 is a normally open and available in single-pole, double-throw (SPDT) or triple-pole, double-throw (TPDT) versions. It has a mercury-free design with a proven precision contact system and a hermetically sealed switch chamber that prevents dust and other contaminants from entering. The case is made of durable thermoplast housing material and features a snap-acting operating point. There are a range of electrical ratings available to meet varying needs.

The operating principle of the D4N-2E22 is based on the movement of the contact arm. The switch is actuated by an external force – such as a lever, push button, or cam – which causes the arm to move back and forth relative to the main body, resulting in the contacts either opening or closing. The arm is spring-loaded and the action is completed when the force is released. This switch is equipped with a snap-acting mechanism that helps ensure reliable repeatability and prevents false readings from occurring.

The D4N-2E22 has a wide range of applications and can be used for a variety of tasks where a reliable limit switch is needed. It can be used on commercial doors, ladders, and conveyor belts to provide an accurate measure of the door, ladder, or belt’s current status. It can also be used to control fuel, air, and water pressure switches. In addition, it can be used in machine tools, presses, and other industrial applications where mechanical limit sensing is required.

The D4N-2E22 is a reliable and cost-effective solution for mechanical limit sensing applications. It features a hermetically sealed switch chamber that helps keep out dust and other contaminants, and a snap-acting operating point that helps ensure reliable repeatability and helps prevent false readings. It is available in single-pole, double-throw (SPDT) and triple-pole, double-throw (TPDT) versions, and has a wide range of electrical ratings available to meet different needs.
