In this current monitoring circuit we use a Reed switch with a LED and a resistor to indicate if is current through a circuit. A Reed switch usually requires between 10 and 100 AT (Ampere-turns = ...

Regular magnets are an irreplaceable solution in many applications in the field of electromechanics. They are used in simple automation (door closing sensors), as well as in more elaborate systems, ...

The rise in interest for renewable energy has led to power designers looking for sensors that are fit-for-purpose in high-voltage photovoltaic applications, observes Martin Reizner. Renewable energy ...
