MT6701 14-Bit Magnetic Angle Sensor Module (AS5600 Alternative)

MT6701 Magnetic Angle Sensor Module is a contactless rotary position sensor (magnetic encoder) that measures absolute angle from 0° to 360°. It uses a rotating diametrically magnetized magnet placed above the chip to detect angle with high resolution. Compared with common Hall encoders, it can provide absolute angle, incremental ABZ quadrature, and PWM/analog outputs (depending on the module breakout and configuration), making it a strong alternative to AS5600 for robotics, motor control, knobs, and automation.

Key Specifications

Angle Measurement

• Measurement type: Absolute rotary angle (0°–360°)

• Resolution (digital): 14-bit (0–16383 counts per revolution)

• Repeatability / stability: Suitable for precision position sensing and control loops

• High-speed tracking: Designed for fast rotation systems

Output Interfaces (Module/Chip Capabilities)

Actual available pins depend on your module version (some breakouts expose only a subset).

• I²C digital output (absolute angle + registers)

• SSI digital output (absolute angle)

• ABZ incremental encoder output (quadrature A/B + index Z)

  • Programmable resolution: typically 1–1024 PPR (module/config dependent)

• PWM output (angle mapped to duty cycle/frame)

• Analog voltage output (DAC output)

• UVW commutation output (for BLDC motor commutation support in some modes)

Power

• Supply voltage: 3.3V to 5V (module-friendly range)

• Current consumption: typically in the mA range (low power for embedded systems)

• Non-volatile memory: Built-in configuration storage (EEPROM)

  • Programming may require higher supply threshold depending on board design

Performance

• Maximum rotational speed: up to tens of thousands RPM (high-speed capable)

• Fast response / low latency: suitable for real-time motion control

• Startup time: quick power-up for embedded devices

Magnetic / Installation Requirements

• Magnet type: Diametrically magnetized (recommended for full 360° angle)

• Mounting: Magnet should be centered above the sensor for best accuracy

• Air gap: Works across a practical air gap range (keep consistent for stable readings)

• Alignment: Proper centering and stable mounting improves linearity and reduces error

Operating Conditions

• Operating temperature: wide industrial range (module suitable for indoor/outdoor electronics projects)

• Noise immunity: Better than optical encoders in dusty/oily environments due to contactless sensing

Module Information (Typical)

Your exact module may vary, but most MT6701 boards are designed for easy prototyping.

• Mounting type: PCB breakout module

• Interface pins: Power + Ground + output pins (I²C/SSI/PWM/ABZ depending on board)

• Form factor: Compact for robotics, gimbals, knobs, and embedded control boards

Main Features (Selling Points)
