Product Overview
The MagnTek MT6815 is an advanced AMR magnetic angle position encoder sensor designed for contactless angle measurement. It offers a full 0 to 360 range sensing capability with high resolution and multiple independent output interfaces including I2C, SPI, Analog, ABZ, PWM, and UVW. Leveraging advanced AMR sensing technology, the MT6815 is insensitive to magnet field strength variations, stray magnetic fields, air gap changes, and off-axis misalignment, making it a robust replacement for optical encoders. Its programmable resolutions and zero index position, along with versatile output options, make it suitable for applications such as robotics control, BLDC motor control, and as a contactless potentiometer.
