Magnasphere Corp.

- Magnasphere Corp. has developed the first significant improvement in two-wire, hermetically sealed, magnetic switching in over 60 years; the patented, award winning Magnasphere Switch. More...

This new technology overcomes the inherent weaknesses of the reed switch (fragility, magnetic tamper susceptibility, size), while retaining the beneficial characteristics (non-contact actuation, sealed contacts). Compared to the Hall Effect switch, the Magnasphere switch exhibits similar performance but does not require power and is less expensive.

A feature unique to the Magnasphere switch is its ability to function as a compact, very low cost stand-alone ferrous proximity sensor. Because the internal contact is a spherical magnet, the device will sense the presence or absence of ferrous material such as steel.

Manufactured in America to ISO standards, the Magnasphere family of switch products offers Design Engineers in all industries solutions to problems inherent in other magnetic switch technologies. Less...

More about Magnasphere Corp.

A privately held company, Magnasphere Corp. was founded in 2002 with the purpose of providing superior performing magnetic contact sensor technology to the residential, commercial, and federal government security markets. Invented by Dr. Randall Woods, Magnasphere represents the first significant improvement in magnetic switch and sensor technology since the introduction of the reed switch in the 1930’s. Magnasphere's patented, award-winning technology establishes new industry standards for high security contact performance while providing an affordable and more effective alternative to reed switch based security contacts.

The Magnasphere® High Security Switch was invented and designed to address the undetected breaches of security that could occur when using the easily exploitable and fragile reed switch, which was originally invented for the telecommunications industry and later adopted for use as a cost effective, yet sub-optimal, security contact. Magnasphere's award-winning, patented technology is virtually unbeatable and unbreakable; ensuring homes, businesses, and high security facilities remain secured.
