At 1.8 mm x 3.8 mm x 2 mm, the LR family of MOSFET relays is said to have the smallest size of any such relay available today. And the relay’s 1-Form-A contact configuration features low power ...

Toshiba has launched two normally open 1-form-A photo-relays that do not need more than 2mA through the input to operate. The input current “reduces energy consumption by approximately 33% when ...

Relays are often used as electrically controlled switches. Unlike transistors, their switch contacts are electrically isolated from the control input. On the other hand, the power dissipation in a ...

I know, I know—discussing the subject of a relay-based sequence switch in the age of omnipresent microprocessors seems to be a waste of time. After all, relays have been in use for many years. Is it ...

This low current relay circuit is designed to be used in battery operated electronic devices. Its operating current is in micro amperes (µA). This is done by using a bistable relay and adding some ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
