D4A-4516N

Snap Action, Limit Switches

The D4A-4516N model is a mechanical switch with a snap action actuation, built by Omron, one of the biggest suppliers of automated switches. It is often used in robotics projects and has a variety of applications. This article covers the working principle and application field of the D4A-4516N.

Application Field

The D4A-4516N is a snap-action switch with a snap-action mechanism, meaning it snaps from one state to another. It is a low-cost solution for a variety of applications, such as controlling motor speed and position and detecting mechanical faults. It is also used in vending machines to detect when an item has been dispensed or when a product is out-of-stock. The switch also has a long life span, with a warranty of one million operations.

Working Principle

The D4A-4516N operates by shifting from one state to another when a certain amount of force is applied to it. This force is applied via a mechanical device, such as a plunger, armature, toggle, or cam. Upon the actuation of the switch, the internal contacts switch from one state to another, activating the desired result. This actuation is highly dynamic, meaning that the switch does not need to stay in the actuated position for a certain amout of time for the operation to take place.

Feature

The D4A-4516N is a gold-plated snap-action switch with an encapsulated construction designed to protect it from dust and corrosion. It is highly reliable, with a strength that is quick to activate and long lasting. It also operates over a wide temperature range (–40 to +77°C), and is compact, measuring 22.2×17.2×14.6 mm.

Conclusion

The Omron D4A-4516N mechanical switch is a snap-action switch with a snap-action mechanism, capable of activating a variety of applications. It is highly reliable and has an encapsulated design to protect against dust and corrosion, and is also highly versatile, operating over a wide temperature range. The D4A-4516N is an ideal solution for a variety of different projects.
