TMR4101 Overview
The TMR4101 magnetic scale sensor contains two push-pull half-bridges, each consisting of two high-sensitivity tunnel magnetoresistance (TMR) elements. The layout of the TMR elements matches the width of the magnetic poles. When the sensor moves along the length of the scale, the sensor outputs two quadrature sine wave signals, each corresponding to the width of a pair of magnetic poles.
TMR4101 Key Features
- Tunneling magnetoresistance (TMR) technology
