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 ...

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 ...

Featuring up to seven switch points, the FLX series of float sensors provide point-level detection of liquids, including those classified as flammable. Available in versions including a heavy-duty ...

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, ...

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, ...

One of the oldest companies in the electronics industry, Coto Technology has been designing and developing small signal switching solutions for over 90 years. These days, the 93-year old company is a ...

[Lucid Science] shows us how to make some simple reed switches. Reed switches are simple components that detect a magnetic field and can close or open a circuit once detected. While not really a thing ...

A new series of magnetically-operated reed proximity switches are said to be suitable replacements for mechanical switches, especially in wet and dirty applications. The MK4/5/13 Series reed sensors ...

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 ...
