Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

The essence of the circuit is for the input of tone and signal to provide an activation for the relay switch. The essence of the circuit is for the input of tone and signal to provide an activation ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

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.

Electromechanical relays are like dinosaurs who haven’t gotten the news that they are supposed to be extinct. Instead, they beget new generations, get designed into new applications, and even take ...

Pickering Interfaces has announced a range of PXI and PXIe microwave relay modules capable of switching signals up to 110GHz in 50Ω. They will be reveals for the first time at IMS in San Diego next ...

Analog Devices revealed details of its second generation of micromachined electro-mechanical relays for automated test. The aim is to provide an alternative to relays – which have good DC performance ...

Landis+Gyr is announcing the addition of four-relay and two-relay load control switches to its North American load management product portfolio. This new generation of switches allows the control of ...
