Since the mid-1980s, semiconductor technology has promised to provide smart power products for solid-state relays that could carry high current and provide unique functions for customers. However, ...

Here’s a MEMS relay with an integrated FET that can handle higher power levels, breaking away from the “low power” moniker associated with MEMS parts. Paul Rako takes a closer look at what makes this ...

Relays and contactors use a variety of technologies to switch signals and power connections. Many devices called relays use similar techniques and topologies, but the terminology can be confusing.

This chapter covers representative general-purpose relays used in the control circuits of most industrial, commercial, and consumer products. Relay names and terminology are in accordance with ...

Omron has designed a relay that can interrupt 200A at 500V, aiming to displace contactors from dc electric vehicle chargers, batteries and solar inverters. “A proprietary gas-less design cools arcs ...

Electromagnetic contactors and relays serve as fundamental components in modern electrical systems, providing reliable switching mechanisms in applications ranging from power distribution to ...

If you've ever wondered how electronic devices manage to control circuits with precision and safety, you're thinking about the magic of relays. Relays act as the unsung heroes in many of our devices, ...

Global revenue in the aircraft relay and contactor market has declined by more than 20 percent as a result of the ongoing Covid-19 pandemic. The market decline is expected to stabilize in 2021, ...

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 ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

Sometimes, the most unexpected detours lead to the most interesting discoveries. After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be ...
