Reed Relays are a class of electrical switches that use a magnetic material to turn a circuit on and off. Unlike a traditional switch, the relay is a two-state device, meaning it can either be open or closed, depending on the current running through the circuit. The number 3572-1220-123 represents a specific type of reed relay. This type of reed relay is designed to control a high-voltage circuit. It has a switching voltage capacity of 4 kV, making it well suited for applications such as industrial measurement and control or medical diagnostic instrumentation. The contact is rated for 120 A at 4 kV, and can be switched at a rate of 5 kHz. This high-power rating makes it ideal for applications that require high levels of current control. The working principle of a reed relay is based on a simple but powerful magnetic effect. A magnetically conductive material (usually made of copper and silicone) is placed across two arms of the relay. When a current passes through the two arms, the magnetic field of the material causes it to be attracted to one arm and repel from the other. This mechanism then causes the arms to move and close the contact between them, thus turning on the circuit. When the current is reversed, the contact between the arms is opened and the circuit turns off. Reed relays are typically used in applications that require fast switching, high accuracy, and an especially reliable connection. Due to their simplicity and robust nature, they are suitable for use in many fields, including medical and industrial technology, aerospace technology, as well as in the automotive and consumer electronics industries. Thanks to its high-voltage capacity, the particular type of reed relay represented by the number 3572-1220-123 is particularly well suited for high-power circuits.
