The rise of smart home technology has transformed how homeowners interact with security systems. Mobile apps, voice control, and home automation platforms have made residential security more accessible and customizable than ever. But while interfaces have advanced, many residential systems still rely on outdated security contact technology that can leave homes vulnerable.

Magnasphere’s advanced magnetic sensors close this gap by delivering commercial-grade security to residential applications, improving protection for doors, windows, safes, and garages while dramatically reducing false alarms and maintenance issues.

The problem with traditional reed switches

Most residential security systems still use reed switch-based magnetic door contacts. These have been standard for decades, but their limitations are well-known:

  • Easily defeated: Reed switches are highly vulnerable to external magnetic tampering. A thief can apply a magnet to the sensor, keeping it closed while opening a door or window undetected.
  • Unreliable over time: Environmental factors like temperature swings, humidity, and vibration can cause reed switches to fail or drift out of alignment, increasing false alarms.
  • Mechanical wear: The fragile reeds inside the glass tube can corrode or break, leading to silent failures that compromise system integrity.

For homeowners, these failures can lead to nuisance alarms, police response fines, and frustration. For integrators, reed switch limitations translate into costly service calls and lower customer satisfaction and potential liability for missed intrusions.

Magnasphere: Smart sensors for smarter security

Magnasphere replaces fragile reed switches with patented, solid-state magnetic sphere technology. The result is a security contact that offers unmatched tamper resistance, reliability, and environmental durability:

  • Tamper-proof design: Magnasphere contacts cannot be bypassed with external magnets. The activation zone requires exact magnetic alignment, rendering traditional manipulation methods useless.
  • Reduced false alarms: The stable, sealed design prevents nuisance alarms caused by shifting doors, fluctuating temperatures, or building movement.
  • Built for long-term use: Tested to 1 million operations, Magnasphere contacts maintain consistent performance for years, reducing service visits and long-term costs.
  • Resistant to harsh conditions: These security contacts perform reliably in extreme cold, heat, moisture, and vibration, ideal for outdoor doors, garages, and detached structures.
Residential applications

Magnasphere security contacts are ideal for residential integrators looking to deliver higher levels of protection and reliability:

  • Entry doors: The most common point of forced entry demands sensors that resist tampering and work flawlessly over time.
  • Windows & sliding doors: Unlike reed switches that break easily, Magnasphere door contacts are robust and don’t break.
  • Safes & secure storage: High-value items require tamper-resistant security contacts that can’t be bypassed by determined intruders.

Homeowners expect security systems that deliver true, long-term protection. Magnasphere door contacts give integrators a proven solution that eliminates the weaknesses of outdated reed switches while enhancing the reliability of any smart home security system.
