Kepler Communications plans to sell terminals to other satellite operators so they can tap into a data-relay constellation it expects to start deploying next year. Credit: Kepler Communications TAMPA, ...

This is an artist's rendering of one of Capella Space's synthetic aperture radar satellites. In orbit, Capella satellites are designed to unfurl an antenna made of a flexible, foldable material.

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...

Devices offer a high-current solution in signal conversion, isolation, and amplification apps With a version boasting the industry's thinnest at 6.2 mm thick, the flareMOVE pluggable terminal-block ...

A simple ohmmeter is all that is needed to troubleshoot a potential relay. After taking all of the connecting wires off of the potential relay, measure the resistance across the 1 and 2 terminals. The ...

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 ...

As you can see in the schematic the 12V battery (or use other voltages) is connected with the plus at terminal T1 and minus at terminal T2. The contact 1 and 4 are connected together as 2 and 3 are ...
