  • Motor feedback systems for the basic performance range
  • 16 sine/cosine periods per revolution
  • Absolute position with a resolution of 512 increments per revolution and 4,096 revolutions with the multiturn system
  • Programming of the position value
  • Electronic type label
  • HIPERFACE® interface
  • Various shaft variants: Hollow and tapered shaft and as shoulder clamping
  • Conforms to RoHs
  • Your benefits

  • The small dimension allows manufacturers of low-power and minimal-power motors to considerably reduce the size of their motors
  • The SEK/SEL52 motor feedback systems are excellently suited for use under rough environmental conditions
  • The capacitive principle of measurement with holistic scanning allows for high axial and radial tolerances
  • Due to the resolver-compatible mechanical components of the SEK/SEL52 motor feedback systems the encoders can be mounted immediately

Number of sine/cosine periods per revolution:16
Number of the absolute ascertainable revolutions:4,096 (Multiturn)
Total number of steps:2,097,152
Measuring step:20 angular seconds (at interpolation of the sine/cosine signals with e.g. 12 Bit)
Integral non-linearity typ.:± 288 angular seconds (Error limits for evaluating sine/cosine period)
typical values at nominal position ± 0,1 mm and + 20 °C
Differential non-linearity:± 72 angular seconds (Non-linearity within a sine/cosine period)
typical values at nominal position ± 0,1 mm and + 20 °C
Operating speed:6,000 /min, up to which the absolute position can be reliably produced
Available memory area:1,792 B (EEPROM 2048) 1)
Maximum number of steps per revolution:512 Via RS485
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.

1) The EMC according to the standards quoted is achieved when the motor feedback system is mounted in an electrically conductive housing, which is connected to the central earthing point of the motor controller via a cable screen and by using the cover (part no. 2048234). Users must perform their own tests when other screen designs are used.
