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.

Pickering Electronics offers its Series 144 high-power reed relays, which switch up to 80W while stacking on a compact 0.25" pitch, to include a variant with an electrostatic shield between the switch ...

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 ...

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 ...

Imagine a component that combines the heavy-duty muscle of a power relay with the surgical precision of a digital signal. That is the essence of a pulse width modulation (PWM) relay. While traditional ...

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 ...

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 ...

Love it or hate it, wiring is a part of any project car. You may loathe the idea of installing relays, but without them, wiring would be much more difficult. HOT ROD ...
