Product Overview
The Magntek MTR611 is an advanced magnetic angle position sensor IC utilizing Anisotropic Magneto Resistor (AMR) technology. It provides contactless angle measurement by generating analog output voltages that change with the direction of the magnetic flux. Featuring dual whetstone bridges for quadrature signal generation, it enables angular measurement up to 180 degrees. The MTR611 operates across a wide voltage range (up to 12V) and temperature range (-40 to 125), making it suitable for various demanding applications including high-accuracy angular position sensing, rotary speed and direction detection, motor control, and robotics control. It is RoHS compliant.
