Snap Action, Limit Switches

D3V-21G5-1C4A-K is a well-known snap action, limit switch produced by OMRON. It is a popular component used in automatic processes and is widely adopted across various applications. This article is going to describe the application field and working principle of the product.

Application Field

D3V-21G5-1C4A-K snap action, limit switch is designed to detect the presence of a target or an object by sensing its contact. It can be used in robotics, electrical and electronic systems, along with automation systems. It can be used as a final component for limit detection, for instance for registration mark detection in packaging machinery.

This switch also finds its application in data processing equipment, control panels, automotive assembly lines and development test systems. It’s a great choice for detecting the presence of objects, whether it’s automatic, semi-automatic or manual equipment. In addition, it can also be used for detecting the end of movement in conveyors or for signifying the opening and closing of doors and windows.

Working Principle

D3V-21G5-1C4A-K snap action, limit switch works on the principle of snapping. It’s designed to provide a filling effect on contact and is advantageous when detecting objects with a minimal gap. Due to this, it allows reliable detection even under severe conditions such as in dusty, watery or steamy environments or when the object to be detected has irregularities in shape, texture or size.

The switch is typically actuated by the contact and releases in one direction with a simple action, with no special operating force required. This opens the contact, allowing the contact to be actuated again. The opening and closing of the switch contact is accompanied by a distinct click sound that helps in determining whether a contact has been made or not. Also, the reset force on the switch contact is adjustable, depending upon the application it is being used for.

Besides, D3V-21G5-1C4A-K snap action, limit switch also offers a variety of structures, allowing it to be used in different types of mounting positions. They come with various actuators, including plunger, cable as well as various roller types, that can be easily adapted depending upon the application requirements. All these features make it an apt choice for a wide range of purposes in automation, control and industrial systems.

To sum up, D3V-21G5-1C4A-K snap action, limit switch is an ideal choice for applications requiring reliable detection with minimal gap. It offers a range of features that makes it an apt choice for various applications. The adjustable reset force and the click signifying a contact make it a great pick for limit detection in a wide range of automation and industrial processes.
