Baumer introduces HDMag magnetic encoders for big shafts

April 14, 2010 - Baumer introduced ultra-precise magnetic hollow-shaft encoders designed for direct mounting onto large size shafts up to 740 mm in diameter. Available in both absolute and incremental versions, HDMag Encoders provide 17-bit absolute single-turn resolution, which results in highly accurate speed, rotation and position data even in low RPM applications such as elevators, water turbines and wind turbines.Measuring just 27 mm wide, these thin profile encoders work well in limited-space environments.FPGA signal processing and integrated offset, amplitude and phase control mean that HDMag Encoders are extremely precise, generating maximum incremental square pulses of 524,288 periods per revolution and a maximum sine/cosine interpolation of 32,768 periods per revolution. Signal processing integrated in the sensor head enables generation of sine/cosine signals or square-wave signals (HTL or TTL).Baumer HDMag Encoders consist of an IP 68 stainless steel encoder wheel that mounts directly on the drive shaft, and an IP67-rated sensing head that is fully-encapsulated and protected from contaminants. Fitted with a protective covering, the magnetic scale on the outside of the encoder wheel is sensed tangentially. These encoders are designed with no moving parts, light source or glass/breakable components, making them highly robust and resistant to shock and vibration. Baumer HDMag Encoders are designed for use in aerospace, energy generation (water and wind turbine), heavy equipment, marine, oil and gas processing, and other harsh-duty applications.
