TMR3101Absolute Rotary Encoder
10-bit Absolute Magnetic Rotary Encoder
1 Introduction
TMR3101 is a contactless absolute magnetic rotary encoder. It is designed
for measuring single-turn absolute angular position from 0 - 360º, or it
can be used as an incremental encoder with pulse output signals.
TMR3101 is designed with Tunneling Magnetoresistance (TMR) angle
sensors and integrated with digital signal processing circuitry. Paired with
a magnet that is magnetized along the radial direction, it can measure 0-360ºangular position
in 10-bit (1024-line) resolution, with the angular resolution at 0.35º. It supports multiple
output interfaces, including PWM, SPI, dual-pulse with zero position, single-pulse with zero
position and direction output, or UVW output.
