Concise Technical Guide to Reed Relays


If used correctly, a reed relay is a superbly reliable device. The switch contacts are hermetically sealed, so do not suffer from oxidization or contamination in the same way as an open electromechanical relay. However in reality, relays are often considered slightly mundane and little thought is given to them which sometimes leaves them vulnerable. Learn how to avoid common issues such as magnetic interaction, temperature effects, contact abuse, ‘hot’ versus ‘cold’ switching and more.
