Key Features:

  • 22-bit single-turn resolution with 12-bit multi-turn for 17.2 billion total counts — highest resolution in Kollmorgen encoder portfolio
  • Glass code disk (G = Glass) provides superior thermal stability and long-term accuracy
  • SINCOS resolver output provides inherent noise immunity for harsh EMI environments
  • IP67 rating enables submersion and extreme contamination resistance
  • Hybrid ceramic bearings eliminate lubrication maintenance and extend service life in extreme temperatures

Installation Requirements:

  • Mount using clamping hub, maximum bore runout: 0.01 mm
  • Resolver cable: shielded twisted pair, maximum length 50 m (analog), 10 m (digital)
  • Excitation frequency must be 1 kHz ± 1% for rated accuracy
  • Shaft coupling: flexible coupling mandatory to absorb axial and radial misalignment
  • Do not exceed 10,000 RPM to maintain encoder accuracy rating
