The reed relay is an outstanding switching device for instruments powered by batteries.
Nowadays, more and more instruments are used in places far away from conventional power sources, and these devices can only rely on battery power. Therefore, any electronic component used must have very low power consumption requirements to enable longer working time.
The reed relay has excellent performance in this application because its contacts are sealed in a glass envelope, providing good airtightness and protection against environmental factors such as dust and moisture. Additionally, the reed relay has excellent insulation performance between its contacts and coil, and the contact resistance is very low and stable, providing assurance for wide bandgap load circuits.
