AS5045B Rotary Sensor12-bit rotary position sensor with digital angle (interface) and PWM and ABI output The AS5045B is a 12-bit rotary position sensor (previously known as encoder) for absolute angular measurement and with an incremental output over a full turn of 360° based on contactless magnetic sensor technology. This device fits perfectly for on-axis applications where a simple 2-pole magnet rotates above or below the sensor IC and the zero position can be programmed into the device. The absolute magnet angular position is measured with a resolution of 12 bit = 4096 positions per revolution and it is provided as a digital value on the serial interface (SSI) and on the PWM output signal. 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
Key Benefits- Highest reliability and durability in harsh environments
- Great flexibility during assembly
- One device for different applications
- Lower material cost (no magnetic shielding needed)
