How Magnetic Rotary Encoders Work

Magnetic rotary encoders use contactless magnetic sensing to track rotational position accurately. At the core, they rely on a magnetic rotary position sensor made up of advanced Hall effect, AMR, GMR, or TMR sensors. These sensors detect changes in the magnetic field generated by a nearby magnetized ring.

The magnetized ring can be designed with either radial or axial magnetization, depending on the mounting setup. Radial magnetization projects the magnetic field outward around the ring’s circumference, while axial magnetization points the field along the ring’s axis. The sensor picks up these magnetic fields, converting them into electrical signals that change as the shaft rotates.

Inside the encoder, sophisticated signal processing takes place to translate these magnetic variations into precise angle and speed data. This ensures reliable 360° position feedback with minimal latency, even in harsh environments affected by dust, oil, or vibration. Thanks to this technology, magnetic rotary encoders deliver accurate rotation measurements without wear, extending lifespan and reducing maintenance.

Mounting & Installation Guide for Magnetic Rotary Encoders

Proper mounting and installation are key to getting accurate feedback from your magnetic rotary encoder. Here’s what to keep in mind:

Recommended Air Gap & Alignment

• Maintain the specified air gap between the magnetic ring and the sensor (typically 0.5 to 2.5 mm) to ensure precise readings.
• Align the encoder sensor and the magnet ring carefully; misalignment can cause signal distortion or loss.
• Radial magnetization requires consistent concentric mounting, while axial magnetization demands precise axial alignment.

Magnet Ring Installation Tips

• Choose the right magnet ring type (radial or axial) based on your application and sensor model.
• Secure the magnet firmly to prevent movement; slight magnet shifts can impact accuracy.
• Avoid magnet contamination with dust or oil during installation to preserve signal quality.

Wiring Diagrams for Common Interfaces

• Follow recommended wiring practices for your encoder’s output type, such as SSI, BiSS-C, SPI, PWM, or incremental A/B/Z signals.
• Use shielded cables and proper grounding to minimize electrical noise, especially in harsh environments.
• Reference specific wiring guides for interface connections, ensuring power supply and signal lines meet your device’s specs.

Calibration & Zero-Position Setup

• After installation, perform calibration to set the zero or reference position. Calibration can be done manually or via software depending on the encoder model.
• Regular recalibration is advised if used in environments with vibration or temperature changes to maintain accuracy.
