Catalog excerpts

The Timken® Mil miniature off-axis magnetic commutating encoder provides a high-resolution, reliable solution offering exceptional operation in tough conditions, long life, easy installation and consistent performance. Durable The M11 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 M11 encoder handles a wider range of shaft-end play and run-out than modular optical encoders. Design The Timken M11 produces on-chip Hall Effect signals to create high resolution quadrature output that determines speed and direction. The M11 is available with index pulse and optional commutation for brushless motors up to 6 poles. One of the smallest commutating encoders available, it is the most accurate magnetic encoder in its class - ideal for small brushless DC motors, servo motors, and microstepping small stepper motors. The M11 fits Nema 11 motors and is capable of up to 1024PPR. Off axis technology provides accuracy not available with on-axis magnetic encoders. The magnetic target is marked for shaftpositioning alignment. Air gap tolerance makes installation quick and easy. 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
