Product Overview

The Magntek MT6620 is a next-generation integrated Hall array sensor IC designed for high-precision off-axis magnetic linear position and angle detection. It leverages a 2mm fixed pitch Hall induction array to enable off-axis angle and displacement detection. The MT6620 offers a convenient client-side self-calibration mode, eliminating data interaction and automating compensation for non-linearities caused by imperfect magnets or installation deviations. It operates reliably within a wide temperature range of -40 to 125 and supports multiple output formats including incremental ABZ, incremental UVW, PWM absolute, and 3-wire SPI bus. Ideal for applications such as brushless DC motor control, linear motor control, robot joint control, and as a replacement for optical gratings.
