Reed Relays: JWD-171-28 Application Field and Working Principle

Reed relays are a type of electrical component that allows for the creation of electrical circuits with minimal current. They’re commonly operated in what is known as “Vacuum Tubes”, making them very reliable and energy efficient. The JWD-171-28 is a reed relay with special features that are suitable for a variety of circuits and devices.

The JWD-171-28 is a reed relay that consists of an evacuation chamber connected to the electrical contacts. When a certain amount of current is passed through the contacts, the air inside the chamber is evacuated – this creates an air gap in the contact that prevents a current from flowing in between the contacts. This action activates the switching mechanism – hence the name “Reed Relay”. The evacuation chamber also provides added protection against dust and other contaminants.

The JWD-171-28 is an excellent choice for high voltage applications. It can handle voltages up to 4,000 volts, making it suitable for power-hungry applications. It is also resistant to temperatures up to +90°C (184°F), and humidity up to 98%.

The JWD-171-28 is often used in the telecommunications industry, for switching circuits in large communication networks. It is also used in the medical and industrial sectors, due to its reliability and small footprint. In addition, it can be used in solar cells and other applications. The JWD-171-28 is also an effective way of controlling the flow of electricity in automotive applications.

The working principle of the JWD-171-28 is relatively simple. It utilises the principle of capacitance – the electrical charge stored within a capacitor holds a certain amount of energy when activated. By passing a certain current through the contacts, the capacitance within the capacitor is charged and the air gap is created. This triggers the relay, and the contacts are closed, allowing electricity to flow through.

In addition, a diode is also incorporated into the device, providing a current path when the capacitance is discharged. This ensures that the contacts are not left open when the relay is in an off state.

The JWD-171-28 is an important component in many automated systems. It is ideal for controlling high voltage applications, due to its reliable operation and high current switching capabilities. It is potentially useful in a wide variety of applications, thanks to its small size and excellent durability.

The JWD-171-28 is a reliable, energy efficient component that can provide an effective and safe electrical switching system for a number of devices. Thanks to its versatile performance, it has become a popular choice for telecommunications, medical, automotive and industrial applications.
