Magn Tek MT6701CT-STD-R

The MagnTek rotary position sensor MT6701 is an IC based on Hall sensing technology. A rotating magnetic field in the x-y sensor plane delivers two sinusoidal output signals indicating the angle (α) between the sensor and the magnetic field direction. The incremental ABZ output mode is available in this sensor series, making the chip suitable to replace various optical encoders. The maximum resolution is 1024 pulse/4096 steps per revolution in binary mode. A standard I²C or SSI interface allows a host microcontroller to read the 14-bit absolute angle position data from MT6701. The absolute angle position is also provided as PWM output or linear analog signal proportional to VDD from a 12-bit DAC. Additionally, the PUSH output indicates the fast air-gap changes between the MT6701 and magnet which can be used to implement a contactless pushbutton function in which the knob can be pressed to move the magnet toward the MT6701.
