The Timken® M9 - the smallest off-axis magnetic encoder on the market - provides a high-resolution, reliable solution offering exceptional operation in tough conditions, long life, easy installation and consistent performance Durable The M9 performs remarkably well in extremes of temperature, with a limit of 125° C which is 40° C higher than most optical encoders this size. Its differential magnetic sensor circuit design protects from magnetic field interference while its larger sensor gap allows it to sustain intense shock loads and vibration. The M9 encoder handles a wider range of shaft-end play and run-out than modular optical encoders. Design The Timken M9 produces on-chip Hall Effect signals to create high resolution quadrature output that determines speed and direction. The M9 is capable of up to 1000PPR and is available with index pulse and line driver. It's ideal for microstepping small stepper motors or for small, high speed servomotors. 800KHz data rate allows up to 12,000 RPM at 1000PPR. Off-axis technology provides accuracy not available in on axis magnetic encoders. The magnetic target is marked for shaftpositioning alignment. Air gap tolerance makes installation quick and easy. Its differential magnetic sensor circuit design protects from magnetic field interference while its larger sensor gap allows it to sustain intense shock loads and vibration. The M9 encoder handles a wider range of shaft-end play and run-out than modular optical encoders. Customized Solutions Timken application engineers create products designed to meet your unique needs. By tailoring the encoder's electronic and physical configurations, the Timken team enhances function and performance to supply a reliable and durable solution. Why Magnetic Encoders? • Highly resistant to liquid or solid particulate in gap between sensor and target • Polymer-bonded multi-pole magnets • High accuracy - less than 10 arc minutes • Compact, low-cost and rugged • Can be customized as a replacement part or to fit new designs • No moving parts
