D4C-2720

Snap Action, Limit Switches

The D4C-2720 is a limit switch that utilizes a snap action for sensing applications. The limit switch uses physical contact to detect a mechanical input, like a lever being pushed or released. When a mechanical force is applied to one of the levers connected to it, the state of the limit switch changes and a signal is sent through wires to indicate this change. For instance, in a typical safety scenario we might implement a limit switch that is triggered when the lever is pushed down, reaching a certain angle. This would indicate that it is safe to move the machinery.

The physical contact of the limit switch is one of the biggest advantages of this type of functional device. Unlike other sensing types, like optical or inductive, it doesn\'t require a line of sight or have any metallic components to interfere with the signal. Additionally, it has a relatively low cost and is immune to interference from electrical and magnetic fields.

The D4C-2720 is designed for simple control applications, with two poles. It has a contact rating of 24V AC/DC and a current rating of 0.2A, making it suitable for low voltage systems. Additionally, it operates between -20 and +55 degrees Celsius, enabling a wide range of potential applications.

When the limit switch is triggered, the snap action causes a set of levers to pivot, changing the position of the internal contacts inside the switch. This change in state of the internal contacts causes a certain electrical switch, which sends the signal to the motor or control system. This design feature makes the switch suitable for applications with fast response time requirements, such as those in industrial automation.

The limit switch body is IP67 sealed, resistant to dust and water splashes. This ensures a long-term operation and allows its use in various industrial and non-industrial applications, including automation, mechanics, robotics, and surveillance among others. The limit switch is also compliant with the relevant regulations like, UL, CE and CSA.

The D4C-2720 is a reliable and easy to use device for sensing applications. Its snap action, low cost, and operational temperature make it a suitable choice for control and automation.
