Reed Relays

Reed relays are a type of electromechanical switch that are used in a variety of electronic applications. They are named after the metal reed contacts that are used to make and break the electrical connection. The reed contacts are sealed in a glass envelope that is filled with an inert gas, usually nitrogen or a vacuum, to prevent oxidation and ensure long-term reliability.

One of the main advantages of reed relays is their fast switching speed, typically in the range of a few milliseconds. They are also capable of switching low-level signals with high accuracy and low contact resistance, making them ideal for use in high-frequency and low-level signal applications. Additionally, they have a long life span and are able to withstand shock and vibration, making them suitable for use in harsh environments.

Reed relays are commonly used in applications such as test and measurement equipment, medical devices, telecommunications, and industrial control systems. They can be designed to switch both AC and DC signals, and can handle a range of voltages and currents depending on the specific application. They are available in a variety of sizes and configurations, including single-pole, double-pole, and latching types, and can be mounted on printed circuit boards or in sockets for easy replacement.
