Reed Relays - JWD-171-10 Application Field and Working Principle

Reed relays are small, low-cost relays that are suitable for low or medium current control applications. They offer a number of advantages over other types of relays, including cost savings, reliability and faster switching speeds. The JWD-171-10 reed relay from Plantation relays takes advantage of these advantages while adding additional features, such as higher current capacity and a smaller physical size. In this article we will discuss its application field and working principle.

Application Field: The JWD-171-10 reed relay from Plantation relays is ideal for a variety of applications, including instrumentation, aerospace and mobile electronics, medical systems, industrial control, and OEM operations. The relay is well-suited for controlling up to 500mA of current, and can be powered with either AC or DC power.

The relay is rated for switching up to 0.4A at 250VAC or 0.2A at 30VDC, and it features a lower power consumption that reduces heat buildup and enhances reliability. The reliable performance and low current capacity make it perfect for applications such as controlling a low-power pump or a valve in an industrial system.

The small size of the JWD-171-10 makes it perfect for applications where space is limited. The relay is designed for use in small enclosures or circuit boards and offers an operating temperature range of -20°C to +60°C.

Working Principle: The JWD-171-10 reed relay from Plantation relays is an electromechanically operated relay that is activated by an external electric current. The relay is composed of a thin wafer of reed material that is sealed in a vacuum, which is usually glass, plastic or ceramic. The reeds are made of a ferromagnetic material and act as the contacts of the relay.

When the coil of the relay is energized, an electromagnetic field is created, which attracts the reed contact and closes the circuit. When the current to the coil is removed, the reed releases its contact and the circuit is opened. The working of the relay is shown in the figure below:

The main advantage of reed relays is their fast switching speed. They are able to switch on and off almost instantaneously, which is important for ensuring the continuity of power in sensitive instruments and industrial automation systems.

Another advantage of reed relays is their low voltage and current requirements. They do not require as much current to switch on and off as other types of relays, which reduces power consumption and increases energy efficiency.

The low power consumption also reduces heat build-up, which increases the longevity and reliability of the relay. Additionally, the JWD-171-10 relay is sealed in a vacuum, which protects it from environmental contamination and ensures reliable performance in even the harshest of conditions.

The JWD-171-10 reed relay from Plantation relays is a versatile and reliable relay that is perfect for a variety of applications. It is small and can be powered with either AC or DC power, making it suitable for even the most space-restricted applications. It has a high-level of reliability and fast switching speeds, which makes it ideal for instrumentation and industrial automation.
