MT6701 Magnetic Encoder Module – 14-Bit 360° Angle Sensor with Radial Magnet
Product Description
The MT6701 Magnetic Induction Angle Measurement Module is a high-precision magnetic angle sensor designed for accurate, non-contact rotational position measurement. It detects the magnetic field component perpendicular to the sensor surface and uses a suitable radial magnet to measure absolute rotational angle from 0° to 360°.
The module uses advanced differential Hall sensing technology to provide fast and stable angular feedback with a system delay of approximately 5μs. With support for rotational speeds up to 55,000 RPM, it is suitable for high-speed motor control, robotics, gimbals, drones, industrial actuators, and other applications requiring real-time angular position feedback.
The MT6701 provides high-resolution 14-bit digital angle data through I2C or SSI, while also supporting multiple output formats including ABZ incremental output, UVW output, PWM, and analog voltage output. This flexibility allows the sensor to be integrated with microcontrollers, motor controllers, servo systems, and other motion-control electronics.
The module also supports a unique push detection function, which can detect changes in the distance between the magnet and sensor. This feature allows the MT6701 to be used in applications requiring both rotary input and push-button functionality.
With an operating temperature range of -40°C to +125°C, the sensor is suitable for a wide range of demanding environments.

Working Principle
The MT6701 measures the magnetic field generated by a radial magnet positioned above the sensor chip.
As the magnet rotates, the direction of the magnetic field changes. The MT6701 detects this change using its differential Hall sensing system and calculates the corresponding absolute angular position.
The sensor continuously provides rotational position information from 0° to 360°, allowing a controller to determine the exact position of the rotating shaft or mechanism without physical contact.
This non-contact sensing method eliminates mechanical wear associated with traditional potentiometers and physical rotary contacts.
High-Speed Angle Measurement
The MT6701 is designed for fast dynamic applications, with a system delay of approximately 5μs and a maximum specified rotational speed of up to 55,000 RPM.
This makes the sensor suitable for high-speed motor feedback applications where low latency and stable angular measurement are important.
Multiple Output Modes
The module provides several output options to accommodate different system requirements.
I2C / SSI
The sensor can provide 14-bit digital absolute angle data through I2C or SSI interfaces, making it suitable for microcontrollers and digital motor-control systems.
ABZ Incremental Output
The module supports ABZ incremental encoder outputs with configurable resolutions from 1 to 1024 lines.
UVW Output
UVW output can be used for suitable BLDC motor commutation and position-feedback applications.
PWM Output
The sensor supports a 12-bit PWM output, allowing angular position to be represented as a variable-duty-cycle signal.
Analog Output
An analog output option is also available for systems that use an ADC input to measure rotational position.
Push Detection Function
In addition to rotational angle measurement, the MT6701 provides a push detection feature that can detect changes in the distance between the magnet and the sensor.
This makes it possible to create combined rotary-and-push user interfaces, such as:
- Rotary control knobs
- Menu selectors
- Volume controls
- Industrial control panels
- Multifunction input devices
EEPROM Configuration
The MT6701 includes internal EEPROM for storing sensor configuration parameters. The supplied specification indicates support for up to 1,000 programming iterations.
This allows users to configure supported sensor parameters and retain settings without requiring external configuration storage.
Magnet Alignment
Correct magnet alignment is important for achieving the specified angle accuracy and linearity.
For best performance:
- Position the radial magnet centrally above the MT6701 sensor.
- Keep the magnet aligned with the center of the chip.
- Maintain the recommended 1mm to 3mm air gap.
- Keep the magnet and sensor parallel where applicable.
- Avoid excessive mechanical wobble during rotation.
Improper alignment or incorrect air gap can reduce accuracy and increase measurement error.

Product Disclaimer
Product images are shown for illustrative and representational purposes only. The actual module may vary slightly in PCB colour, component placement, connector arrangement, magnet appearance, dimensions, or other visual details depending on the manufacturing batch.
The included radial magnet is required for magnetic angle measurement. Proper magnet selection, alignment, orientation, and air gap are important for achieving accurate results.
Actual sensor performance depends on magnet size and strength, air gap, alignment, rotational speed, temperature, PCB installation, and system configuration.
Important Notes
Magnet Alignment
For accurate angle measurement, the radial magnet should be centered directly over the MT6701 chip.
Recommended Air Gap
A recommended air gap of approximately 1mm to 3mm should be maintained between the magnet and sensor, subject to the actual magnet and application configuration.
Non-Contact Sensor
The MT6701 does not require physical contact with the rotating shaft, reducing mechanical wear and making it suitable for long-term rotational sensing.
Electrical Connection
Use a suitable 3.3V to 5.0V supply and verify the selected output interface and pin configuration before connecting the sensor to a microcontroller or motor controller.
