D4N-4220 Application Field and Working Principle
The D4N-4220 originates from Japan\'s Omron Corporation, and is one of a growing number of Limit Switches using Snap Action technology. Becoming popular in industrial applications, these switches are typically used to detect contact or release of a lid, contact motion or the orientation of a product.
The switch body is manufactured from a durable, flame-resistant material with a high degree of corrosion resistance. The contacts are highly reliable, with a maximum allowable contact current of 5A at 250V or 0.5A at 24V respectively. This is perfect for low-power applications in severe conditions.
The limit switch is actuated by a lever that snaps onto a ball bearing in order to initiate a closing or opening motion. When the lever is in the closed position, it has an SPDT (Single Pole Double Throw) configuration, whereby one contact is closed and the other is opened. When it is released, the contacts switch places and the limit switch is deactivated.
The switch is especially suited for installation in areas with limited space. It is designed for easy installation, via direct "snap-in" - no tools are required to secure the D4N-4220 in place. The enclosure is also sealed from dust and liquids, making it suitable for general industrial use. This, combined with its small size, makes it ideal for applications in limited available space or when high moisture or dirt levels are present.
In terms of applications, the range of devices opens up a wealth of possibilities. Examples include detecting a lid closure, the movement of a part or product, or the switch in correspondence with an angle of rotation. Its flexibility makes it an ideal companion for applications in production, process automation and robotic systems.
No matter what your application needs, you are sure to find a use for the D4N-4220 Limit Switch. A quality product from Omron Corporation, its reliable performance and reliability can help you meet the demands of even the most challenging production and industrial settings.
