Snap action and limit switches are widely used in a variety of industrial applications, and D4N-7287 is a equipment that falls under these two divisions. In this article, we will discuss the application field and working principle of D4N-7287 type limit switch.

The D4N-7287 type Limit Switch is a push-to-open switch with rated loads of 10A at 120VAC, 20A at 250VAC. The switch purpose is to detect the presence or absence of objects in order to operate the related machinery. In terms of application field, it is typically used in safety interlock circuits, guarding application, position/belt speed monitoring and various control systems.

When it comes to working principle of the D4N-7287, an electromechanical relay is responsible for switching larger loads than the switch is rated for. This type of limit switch is enabled by an actuator, which is usually mounted on the side of the limit switch. The actuator is spring loaded, which keeps the contacts of the switch closed until a specified force, such as a turning force, acts on the actuator and breaks the contacts. As the contacts are broken, power to the load is cut off and the electrical equipment or device is stopped.

To ensure proper functioning of the D4N-7287, it should be installed in dry, clean and free from conductive dust environment. The installation environment temperature should be between -20°C and +60°C and the switch is not to be used in an explosive atmosphere. Furthermore, it should be operated by using the specified voltage and power source, otherwise, malfunctioning may occur.

In order to reset the limit switch, the actuator can be pressed and it will be the original state of contact. In short, this type limit switch functions by mechanically pressing an object which nudges the actuator, thus causing the contacts to open or close, controlling the flow of electricity.

The D4N-7287 type limit switch is highly durable, with a wide variety of applications in various industries such as automotive, manufacturing, industrial control, etc. Its working principle and maintenance procedures have been discussed above. With the right knowledge and careful operation, one can easily make the most of this advanced switch, ensuring optimal performances and a longer operating life.
