ABH001-00 GMR Gradient Sensors (Gradiometers) offer unparalleled magnetic gradient sensing. Two pairs of unshielded GMR bridge resistors provide directional sensing of small gradients over a wide range of magnetic field strength. The devices are sensitive only to gradients with low sensitivity to constant external magnetic noise. This allows these sensors to operate in high noise environments, such as near electric motors or high-current wires.
Key Features:
- Extremely High Sensitivity to Applied Magnetic Fields
- Wheatstone Bridge Analog Output
- Temperature to 150 degrees Continuous
- Wide Linear Range of Operation
- Near-Zero Voltage Operation
- DC to >1MHz Frequency Response
- MSOP Package
Applications:
- General Differential Field Sensing
- Gear Tooth and Encoder Speed and Position Sensing
- Low Voltage, High Temperature Applications
