MT6701QT Magnetic Encoder Angle Measurement Sensor Module Alternative to AS5600 High‑Precision Rotation Detector For Servo Motor

MT6701QT Magnetic Encoder Module

📌 Product Overview The MT6701QT magnetic encoder module adopts MagnTek new‑generation MT6701 magnetic angle encoder chip based on differential Hall sensing principle. It detects the rotating magnetic field from a paired‑pole radial magnet and outputs 0‑360° absolute angle signal. This module supports multi‑mode signal output including ABZ/UVW incremental signal, analog / PWM absolute value and 14‑bit digital angle data via I2C / SSI interface. It also integrates press detection function to realize rotation‑and‑push button control. Compact and high‑precision design, it can be used as a replacement for AS5600 for motor angle measurement, rotary knob and industrial position feedback projects. ✨ Core Features

• Differential Hall principle for 0°‑360° full‑range absolute angle measurement
• Wide supply voltage: 3.3V‑5.0V, operating temperature: -40℃‑125℃
• Typical linearity error less than ±1°, full‑temperature‑range error less than ±1.5°
• Ultra‑low system delay of 5 μs, maximum support rotation speed up to 55000 RPM
• I2C / SSI interface for reading 14‑bit high‑resolution angle value
• ABZ incremental output, resolution adjustable from 1‑1024 lines
• UVW incremental output, pole pairs configurable from 1‑16
• 12‑bit PWM output or 12‑bit DAC analog voltage output
• Built‑in press detection function for rotary push‑button application
• Onboard EEPROM, supports over 1000 programming cycles

• The matching magnet must be installed right above the chip center
• Keep the magnet and chip at a proper working distance
• Avoid strong external magnetic field interference during operation
• Do not apply over‑voltage beyond 5V to prevent chip damage
• EEPROM configuration should be written reasonably to avoid invalid repeated burning
