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.
