Our linear Hall-effect sensor advantages
Choose between multiple output types for your system needs:
- Unipolar output enables you to achieve enhanced resolution of the strength or magnitude of the magnetic field.
- Bipolar output allows you to determine the magnitude of the magnetic field if the polarity is unknown.
- Pulse-width modulation eliminates the need for an analog-to-digital converter, increasing immunity to external noise and reducing cost.
