  • HIPERFACE® motor feedback systems for large hollow shaft and torque motors
  • 64 sine/cosine periods per revolution
  • Absolute position with a resolution of 2,048 increments per revolution
  • Programming of the position value and electronic type label
  • HIPERFACE® interface
  • Turn & play - for simple assembly without tools
  • High resistance to shock and vibration due to holistic scanning
  • Bearingless motor feedback system
  • Your benefits

  • Direct seat on the drive shaft renders transmission elements such as toothed belt or coupling superfluous
  • The simplified, compact design is wear-free, thus helping to reduce maintenance costs
  • Measuring accuracy is no longer affected by magnetic fields thanks to the capacitive measuring principle
  • Time-saving mounting, since no mounting tools are required: simply fit it on, turn it and start
  • The minimal dimensions enable you to save space and weight, allowing for a more efficient use of space

Number of the absolute ascertainable revolutions:1 (Singleturn)
Total number of steps:2,048 via RS485
Measuring step:5 angular seconds (at interpolation of the sine/cosine signals with e.g. 12 Bit)
Integral non-linearity typ.:± 72 angular seconds (Error limits for evaluating sine/cosine period)
typical values at nominal position ± 0,1 mm and + 20 °C
Differential non-linearity:± 45 angular seconds (Non-linearity within a sine/cosine period)
typical values at nominal position ± 0,1 mm and + 20 °C
Operating speed:3,000 /min, up to which the absolute position can be reliably produced
Available memory area:1,792 B (EEPROM 2048) 1)
Latency:100 µs
1) If applying the electronic type label, in connection with numeric controllers, attention should be paid to Patent EP 425 912 B 2, application of the elektronic type label in connection with speed regulation ist exempt.

Ambient data
Working temperature range:-30 °C ... 115 °C
Storage temperature range:-50 °C ... 125 °C, without package
Relative humidity / Condensation:90 %, Condensation not permitted
Resistance to shocks:100 g, 6 ms (according to EN 60068-2-27)
Resistance to vibration:30 g, 10 Hz ... 2,000 Hz (according to EN 60068-2-6)
