Reed Relay

Compared to other relay technologies, reed relays have the advantages of hermetically sealed contacts, low coil power, fast operation, and small size. However, as with any technology, there are various aspects to consider. Since the reed switch is the switching component used in a reed relay, please see the Reed Switch Technical section for further information on reed relay aspects related to the reed switch, such as electrical load, operate time, contact bounce, and shock & vibration.

Reed relays are normally mounted to circuit boards. The reed relay terminals should not be bent, for example, to make them self-clinching. Avoid bending the terminals to fit misaligned holes. Unshielded relays placed too close to each other can influence each other. Shielded relays are an option in this case and for environments with high magnetic fields from motors, magnets, etc.
