MAGNASPHERE

MAGNASPHERE Corp is a company that was founded by Dr.Wood around 2002. Dr. Woods had noticed how easy it was to defeat an entire reed switch security system with a simple magnet. Reed switches were popularly used since the 1930s. In 2002, Dr. Woods went on to develop a superior magnetic switch and sensor technology for the commercial, residential and government security markets. His award-winning and patented switch called the MAGNASPHERE Switch became the standard for high-security switches with the same level of magnetic defeat protection used in Government's most secured facilities, but at an affordable cost.

MAGNASPHERE Switch Series

Protect security systems from outside magnetic defeats with affordable and compact high-security contact switches from the Magnasphere switch series. Many security systems are not as secured because they utilize conventional reed switches that are exploitable and fragile. Magnetic reed switches are easily defeated with a simple magnet. Dr. Randall Woods, the inventor behind Magnasphere technology, became aware of this problem when one of his neighbor's alarm systems did not go off after an intrusion. He came up with a security switch solution that was highly resistant to magnetic defeat tampering and unbreakable with its robust all-metal construction design.

Today, the federal government uses similar switch technology with the same level of defeat protection, but at a huge expense. Magnasphere switch technology allows residential and commercial establishments to enhance security access control and intrusion detection at just a fraction of the cost and size compared to ones used in the government's most secured facilities.

At JMAC Supply, you can find a variety of Magnasphere switch products for special applications:

Form A (Normally Open)

  • N Series - requires no magnet actuator and can be used as a close tolerance ferrous metal proximity sensor
  • TW Series - with a wider actuation zone in the X or Y axis than other Form A MAGNASPHERE switches. Ideal for door and window sensors in closed-loop alarm systems.
Form B (Normally Open)
  • L Series - a compact, low-cost two-wire switch with remarkable ferrous metal proximity sensing. This series does not require a magnet actuator.
  • S Series - with a wider actuation zone in the X or Y axis than other Form B MAGNASPHERE switches. Ideal for door and window sensors in open-loop alarm systems.
