PHOENIX, Arizona, June 2. IN the June issue of Swimming World Magazine, Publisher Brent Rutemiller calls for a suspension of electronic relay take-off platforms in this month's edition of A Voice for ...

The reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.

Manufacturers of switches and relays have faced several big challenges over the past few years. OEMs, particularly in higher-reliability markets, continue to look for greater flexibility and ...

Inspired by input from panel builders, system integrators and end users around the world, Rockwell Automation engineers developed the new Allen-Bradley E300 electronic overload relay. The E300 ...

Interested in DIY a simple electronic impulse relay module? T. K. Hareendran designs an impulse relay circuit that mimics the functions of a conventional electromechanical impulse relay. This module ...

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, ...

In this QuickChat, James Morra, senior editor at Electronic Design, sits down with Robert King, product development manager at Pickering Electronics, to explore the evolving role of high-voltage ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

Relays are available for single-phase current monitoring, single-phase voltage monitoring, three-phase voltage monitoring and phase monitoring. Unlike the company's existing relays, each BL relay ...

ONE of the more useful by-products of the rapid development of radio technique is the use of thermionic valves as relays of negligible input power, freedom from contact troubles and practically ...

A critical component of your engine's support accessories is the cooling system. Gone are the days of a manual belt-driven radiator cooling fan as we have ushered in the more powerful electric fan.
