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.

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 ...

A switch-matrix board that routes any of eight programmable voltage signals to any of 96 output pins. The board generates digital patterns up to 20 MHz and 30 kV and has 36 Mbytes of memory. Four ...

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 ...
