There are two sensor choices, reed and Hall-effect switches. They have many similarities but also significant differences, explains Martin Reizner. Demand for reed switches has risen significantly in ...

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 ...

A line of reed switches suits applications such as liquid-level sensors, proximity sensors, automotive, security, and other on/off functions where standard mechanical switches do not work. Glass ...

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, ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...

The ubiquitous magnetic reed switch has a unique set of properties, including tera-ohm isolation when OFF, milliohm resistance when ON, zero power operation, around one watt hot switching capability, ...

If you love tinkering, ESPHome is a fantastic way to build custom smart home devices. This open-source firmware framework ...

MEDER electronic Inc. introduces the MK26 line of reed sensors, which feature extremely high switching power in combination with a compact design. MEDER electronic Inc. introduces the MK26 line of ...

They use a buoyant float to gauge a fluid level. In most models, the float carries permanent magnets and encircles a stationary stem. As the float rises or drops with fluid level, the magnetic field ...

This file type includes high resolution graphics and schematics. Conventional magnetic reed relays provide excellent low-power characteristics combined with a low level of electrostatic discharge (ESD ...
