If used correctly, a reed relay is a superbly reliable device. The switch contacts are hermetically sealed and do not suffer from oxidization in the same way as an open electro-mechanical relay. Although in reality, relays are often considered slightly mundane and little thought is given to them which sometimes leaves them vulnerable. Topics covered in this concise guide Download this concise guide to maximise the reliability of your design whilst switching with Reed Relays. Topics include: Magnetic interaction; Temperature effects; Contact abuse; ‘Hot’ versus ‘cold’ switching; Why place a diode across a relay coil. Pickering Electronics have been specialising in high-quality reed relay designs for over 50 years and have published this guide to support engineers who regularly use reed relays.
