Although many electromechanical relays have been replaced by their solid-state cousins, they still have their place in electronic systems and they are still being manufactured. The early telephone ...

Here’s an interesting introduction to Reed Relays, Mercury Displacement Relays, Contactors, Polar Relays, Latching Relays, T-Bar Relays, Time Delay Relays, and Stepping Relays. Here’s an interesting ...

Electromechanical relays can be manufactured with high-frequency RF characteristics that allow them to pass and switch signals in the 7-GHz range and beyond with the proper packaging. Two key RF ...

A line of general-purpose electromechanical relays comes in three mounting styles for use with motors that constantly cycle on and off. HD-1 relays are rated for 40A at 240 VAC/30 VDC, 1 HP at 120VAC, ...

Since the introduction of solid-state relays some decades ago, the debate over which is better, solid-state relays (SSRs) or electromechanical relays (EMRs), has gone on. The general answer is neither ...
