Reed Relay
Item Name Code (INC) 30544
 |
A relay consisting of an energizing coil and a metallic reed switch mechanism. The reeds serve as both core and contacts, which are not hinged or pivoted and which move by flexure when acted upon by a magnetic field induced by energization of the coil. It may also include a biasing magnet. The biasing magnet, either aids or opposes the movement of the reeds and the opening or closing of the contacts. For items in which actuation is dependent on the resonant frequency of the reeds see RELAY, RESONANT REED. Excludes RELAY, ELECTROMAGNETIC.
Additional Information for Reed Relay
Reed relays are a type of electrical relay that use a reed switch as the switching element. They are part of the supply class "Relays And Solenoids" in the supply group "Electrical And Electronic Equipment Components."
A reed switch is a type of electrical switch that consists of two metal reeds sealed in a glass tube filled with an inert gas. When a magnetic field is applied to the switch, the reeds are attracted to each other and make contact, closing the circuit. When the magnetic field is removed, the reeds spring back to their original position, opening the circuit.
Reed relays are commonly used in applications where low power consumption, high reliability, and fast switching times are required. They are often used in telecommunications, test and measurement equipment, medical devices, and industrial control systems.
One of the main advantages of reed relays is their ability to switch very low-level signals accurately. They have a low contact resistance and can handle both AC and DC signals. Reed relays also have a long operational life and are resistant to shock and vibration.
In terms of construction, reed relays typically consist of a reed switch, a coil, and a set of contacts. When the coil is energized, it creates a magnetic field that attracts the reeds and closes the contacts. When the coil is de-energized, the contacts open.
Overall, reed relays are a versatile and reliable type of relay that are widely used in various electrical and electronic applications.
