Reed relays are invaluable components in a range of electronic circuits, serving to dictate the flow of electrical current and enable or disable circuits when needed. One type of reed relay, the JWD-172-1, is designed to handle up to 1000V and is capable of switching currents of up to 5A. This type of relay is found in a variety of industrial applications, particularly those requiring the handling of high voltages. Here we discuss the application fields and working principle of the JWD-172-1 reed relay.

Application Field

As mentioned, the JWD-172-1 is designed specifically to provide reliable performance when handling very high voltages. As such, it works best in industrial applications such as power supplies, motors, and test instruments where high voltages are present. Its design also means that the JWD-172-1 is the perfect choice for applications needing to switch currents of up to 5A, as it has a coil resistance of just 57 ohms. This low resistance ensures that even in high-current applications the relay does not become overloaded.

Other than in applications requiring the handling of high voltages and currents, the JWD-172-1 can also find use in automotive and medical equipment, thanks to its reliable performance, small size, and ability to handle high voltages. The small size of this particular reed relay means that it requires smaller mounting spaces than other types of relays, giving it an advantage in applications where space is an issue.

Working Principle

The JWD-172-1 reed relay works on a simple principle – an electromagnetically-driven contact system. At the heart of the relay lies a small but powerful electromagnet – called the coil – which acts as an anchor. When the relay is switched on, the coil is energised and draws the normally open (NO) contacts together, which closes the circuit and allows the current to flow. When the relay is switched off, the magnet’s pull is removed and the contacts open, preventing any further current from passing. The duration for which the contacts remain closed or open depends on the duration of the electric current.

The key feature of the JWD-172-1 reed relay is its ability to switch at very high voltages, which allows it to handle large currents with ease. The magnet also serves to protect the contacts from overheating under high current loads, as the energy generated by the coil is dissipated by the magnet when the relay is in use, reducing the risk of damage being caused to the contacts. The relay also has a specially designed internal shield, which helps to protect the reed switches, and prolongs the relay’s life-span.

Thanks to its high voltage handling capabilities, the JWD-172-1 reed relay is a reliable, durable, and versatile solution to applications requiring the handling of high voltages and currents. As one of the few reed relays capably of handling such high voltages, the JWD-172-1 has become a popular choice in industrial and automotive applications, as it can provide high performance with minimal energy consumption.
