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.

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 ...

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 ...

This new range of AC and DC solid state switching devices is an ideal solution for switching resistive, slightly inductive and motor loads, thanks to the reduced size per unit - starting at only ...

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 ...

The U.S. Defense Advanced Research Projects Agency (DARPA) is entering the first phase of the Persistent Optical Wireless Energy Relay (POWER) program, which is intended to revolutionize energy ...

Meeting the requirements of MIL-PRF-83536 specification and ISO-9001 certification, this new series of power relays has been specifically engineered for mission-critical commercial aviation, defence ...

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 ...

CLACTON-ON-SEA, England--(BUSINESS WIRE)--Leading manufacturer of high performance reed relays, Pickering Electronics has increased the power ratings of four of its most popular relay series – ...

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 ...
