MDT Multidimensional Technology TMR3101 Magnetic Absolute Position Encoder

Introduction

TMR3101 is a non-contact reluctance absolute position encoder that can be used to accurately measure any within a single circle of 360°. It can also output pulse signals and be used as an incremental encoder. The TMR3101 non-contact magnetic absolute position encoder is integrated with a tunnel magnetoresistance (TMR) sensor and a digital processing chip. With radially magnetized magnets,360° measurement and rotational speed measurement can be completed. The output in is 1024 lines,and the resolution can reach 0.35°. Optional pulse modulation output (PWM),serial digital output (SPI),bi-phase pulse/zero output,single-phase pulse/zero/direction output,three-phase UVW output and other output modes.
