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 ...

Just about everywhere you go, there’s a reed switch nearby that’s quietly going about its work. Reed switches are so ubiquitous that you’re probably never more than a few feet away from one at any ...

This white paper is a discussion of Coto Technology on emerging reed sensing technologies. The sensor incorporates the best features of conventional reed switches combined with the inherent benefits ...

Selecting the right sensor is a critical step in electronic system design, influencing accuracy, reliability, and long-term ...

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 ...

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 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, ...

The SR4J series of ultra-small, surface-mount magnetic reed switches is available for non-contact position sensing applications. These J-leaded devices are based on ...
