Motor feedback systems rotary HIPERFACE®

Compact motor feedback system for motors with 40 mm square

Your Benefits

  • The small dimension allows manufacturers of low-power and minimalpower motors to considerably reduce the size of their motors
  • The SEK/SEL34 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


Compact motor feedback system for motors with 40 mm square

The new SEK/SEL34 motor feedback systems with holistic scanning were designed specially for the needs of motors with a flange size of 40 mm. The SEL34 is impressive thanks to its compact design with real multiturn and a mechanical drive. The centerpiece of the product family is a bearing-free, capacitive sensor element. The holistic scanning system almost completely compensates for eccentricity errors and is very robust. Dispensing with consumable parts ensures that error sources are ruled out as much as possible. Thanks to the capacitive measuring system, ball bearings can be dispensed with, thus making it possible to significantly reduce wear and heat build-up. The SEK/SEL34 motor feedback systems unite extreme robustness, the multiturn system and all the advantages of the HIPERFACE® interface in a very compact design.
