Product Overview

The MagnTek MT6815 is an advanced rotary position sensor IC utilizing AMR magnetic sensing technology for contactless angle measurement. It offers a full 0 to 360 range sensing capability with independent output interfaces including I2C, SPI, Analog, ABZ, PWM, and UVW. Key benefits include high resolution (up to 14-bit core), user programmability for resolution and zero index position, and robustness against magnet variations, stray fields, air gap changes, and off-axis misalignment. Its versatility makes it suitable for replacing optical encoders and for applications such as BLDC motor control, robotics, and as a contactless potentiometer.
