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 = ...

All credit to Thomas Langewouters for an unusual reed switch ladder circuit for liquid level sensing. You can find it on his website here. He went on to use a more traditional two-terminal design, but ...

This simple Door Chime protects the door and gives a loud Alarm tone when there is an attempt of theft. The circuit is too simple and battery operated. A Normally Closed (NC) reed switch and magnet is ...

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 ...

Pickering’s smallest miniature SIP reed relay with a power rating up to 80 Watts offers alternative to mercury wetted reed relays or electromechanical relays Leading manufacturer of high performance ...
