Motor feedback systems rotary HIPERFACE®

Flexible, robust, saves space: SICK capacitive motor feedback systems

Your Benefits

  • Its small dimensions allow manufacturers of small and very small motors to achieve a significant reduction in the length of their motors
  • The SEK/SEL37 motor feedback systems are particularly suitable for use under harsh ambient conditions
  • The capacitive measurement principle with holistic sensing enables high axial and radial tolerances
  • Due to the uniform mechanical component, a high level of flexibility can be achieved with SKS/SKM36 when using with various encoder systems


Flexible, robust, saves space: SICK capacitive motor feedback systems

The SEK/SEL34 and SEK/SEL37 capacitive motor feedback systems with the holistic scanning process were developed specially for the requirements of servo motors with a 40 mm edge dimension. The centerpiece of the product family is a bearing-free, capacitive sensor element. The holistic scanning process virtually offsets eccentricity errors and is extremely resistant to shock and vibrations. The motor feedback systems also have a high temperature resistance. Thanks to the capacitative measurement system, balls bearings are not needed, meaning wear and heat development is significantly reduced. The SEK/SEL motor feedback systems unite extreme reliability, multiturn capability and all the advantages of the HIPERFACE® interface in a very compact design.
