The unique AHK991-14E is a high-field, low voltage, low power, TMR magnetic switch, designed for MRI detection in implantable medical devices.
The sensors have a 350 mT (3500 Oe) typical operate point, which is high enough to detect MRI fields or strong, rare-earth magnets in close proximity. Such high fields disrupt most other magnetic sensors.
The sensors can withstand unlimited fields without
being damaged or turning off.
Unlike Hall effect or other sensors, the switch is sensitive to magnetic fields in any direction.
Key Specifications:
350 mT operate point
0.9 to 1.8 V
2 µA typical supply current
3000 Hz switching speed
-40 to 85°C
