D4N-2B25

Snap Action, Limit Switches are devices used to control electrical circuits by sensing the presence or absence of an object. D4N-2B25 is a type of snap action, limit switch commonly used in the industrial automation industry. It is typically found in a variety of applications, ranging from fluid flow control, temperature monitoring and control, motor speed and current sensing, down to simple circuits that require a way to detect the presence or absence of some object.

1. The Construction of D4N-2B25

The D4N-2B25 is a high-grade, reinforced mechanical switch that is built with an epoxy resin cast and hardened materials. Its base is made of steel, usually stainless steel, and is combined with a heavy-duty switch body. The electrical contact of the switch is made with silver alloy or copper alloy and is enclosed in a hermetically sealed casing. With its external cable, this product is designed with a vandal-resistant, non-rotating construction making it suitable for use in industrial applications in areas with harsh conditions.

2. D4N-2B25 Application Field

The D4N-2B25 snap action, limit switch is widely used in industrial applications due to its reliable performance, stability and accuracy. It is suitable for a variety of applications across industries such as automobile manufacturing, power plant operations, chemical or petroleum plants, trains, ships, elevators, packaging lines, and textile machines. Its external cable and vandal-resistant, non-rotating structure makes it suitable for heavy-duty applications where extreme conditions are present.

3. Working Principle

The working principle of the D4N-2B25 snap action, limit switch is quite simple. It is designed to detect the presence or absence of some object by activating an electrical circuit when an object is detected and deactivating it when an object is not detected. This type of switch consists of two different positions, namely the normally open and normally closed. In the normally open position, the electrical circuit is activated when the switch makes an electrical connection. On the other hand, in the normally closed position, the circuit is deactivated when the switch makes an electrical connection.

4. Advantages

The D4N-2B25 snap action, limit switch is a durable, dependable and cost-effective switch. It is designed with an epoxy resin cast and hardened materials, making it resistant to shocks, vibrations, and environmental factors. Its stainless steel and heavy-duty switch body as well as silver alloy or copper alloy electrical contact ensures that it can resist heat, salt spray, and corrosive environments. Furthermore, its vandal-resistant, non-rotating construction makes it suitable for use in areas with harsh conditions.

Conclusion

The D4N-2B25 snap action, limit switch is a versatile switch, designed for a number of industrial applications across industries. It is built with an epoxy resin cast and hardened materials, making it resistant to shocks, vibrations and environmental factors. Its external cable and vandal-resistant, non-rotating construction is suitable for heavy-duty applications where extreme conditions are present, making it suitable for a variety of applications such as fluid flow control, temperature monitoring and control, motor speed and current sensing, and more.
