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 ...

Reed relays contain a reed switch, a coil for creating a magnetic field, an optional diode for handling back EMF from the coil, and an encapsulating package with connection terminals. In many ways, a ...

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 ...

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 ...
