The M9 Miniature Modular Magnetic Encoder is the smallest off-axis modular magnetic encoder on the market. It offers reliable performance at an economical price with resolutions up to 1000 CPR (Cycles Per Revolution). The M9 includes electromagnetic interference (EMI) protection circuitry and a differential magnetic sensor circuit design that protects it from interfering magnetic fields. Its 800KHz data rate allows up to 12,000 RPM at 1000 CPR. The magnetic technology provides operational advantages over conventional optical encoders in high-temperature, shock and vibration environments.
