Magn Tek MT6816CT-ACD-R

The MagnTek rotary position sensor MT6816 is an IC based on advanced AMR technology. A rotating magnetic field in the x-y sensor plane delivers two sinusoidal output signals which indicating the angle (α) between the sensor and the magnetic field direction.

The sensor is only sensitive to the magnetic field direction in x-y plane as the sensing element output is specially designed to be independent from the magnet field strength. This allows the device to be less sensitive to magnet variations, stray magnetic fields, air gap changes and off-axis misalignment.

The incremental ABZ output mode is available in this sensor series, making the chip suitable to replace various optical encoders. The maximum resolution is 4096 steps or 1024 pulses per revolution

A standard SPI (3-Wire or 4-Wire) interface allows a host microcontroller to read out the 14-bit absolute angle position data from MT6816. The absolute angle position is also provided as a 12bit PWM output.
