Description
The TMR3102 is a contactless, high-precision, and high-speed magnetic rotary encoder sensor, which integrated with tunneling magnetoresistance (TMR) sensors and CMOS digital signal processing circuitry.
The TMR3102 senses the single pole-pair magnet rotation above the chip by TMR sensors, collects the rotating magnetic field signal, transmits it to the digital processing unit, and calculates the rotation angle. TMR3102P outputs 12-bit absolute position signal through SPI communication protocol. At the same time, it is able to output analog and PWM signals, with rotational speed up to 20,000 RPM.
