AS5145B Rotary Sensor
12-bit rotary position sensor with digital angle (Interface), PWM and ABI output
The AS5145B is a contactless magnetic rotary position sensor for accurate angular measurement over a full turn of 360° and over an extended ambient temperature range of -40°C to 150°C. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879° = 4096 positions per revolution via a serial bit stream and as a PWM signal. The incremental output (=ABI-interface) is preprogrammed for 12 bit = 4096 positions.
Key Features
- Contactless absolute angle position measurement and motion sensing
- User programmable zero position
- Multiple interfaces (SSI, ABI, PWM)
- Immune to external magnetic stray fields
