Reed Switch Feature Comparison

Switch Features	REED	MAGNASPHERE
Construction	Glass/Metal Oxide Bond	All Metal Switch
Durability	Fragile Even When Packaged	Virtually Indestructible
Plastic Insert Molding	Fragility a Problem	Can Be Insert Molded
Ferrous Proximity Sensor	Requires Additional Magnet / Cost and Size Issues	Only Stand-Alone Technology with Capability / Lower Cost
Magnetic Activation – Defeat	Globally – Easily Defeated	Defined Zone – Cannot Defeat
High Voltage Exposure	Permanent Contact Welding	Resistant to Contact Welding
Electromagnetic Interference	Easily Affected	Not Affected

MAGNASPHERE is also a superior replacement for Hall Effect switches. (1) Does not require a third wire as a power source. (2) Does not drain battery supply during stand-by. (3) Operates on similar magnetic field strengths. (4) Does not require RFI/EMI protective filter. (5) Does not sense only one magnetic polarity. (6) Uses similar PCB “real estate” area. (7) Does not require shielded wire harness. (8) Robust to shock forces and impact.
