Motor feedback systems rotary HIPERFACE®

High-resolution motor feedback system

Your Benefits

  • Motor feedback system with HIPERFACE® interface
  • High shock/vibration resistance thanks to built-in metal code disk
  • Consistent motor design due to identical size of single and multiturn design
  • To use of a motor feedback system certified to SIL2/PL d makes it easier to have your system certified.
  • Very smooth running thanks to maximum ball bearing distance


High-resolution motor feedback system

Used worldwide in a large variety of applications and environments - motor feedback systems of the SRS/SRM50 product family. With 1024 sine/cosine signals per revolution, this family represents the high-end solution of motor feedback systems with HIPERFACE® interface. They use a precise metal code disk and the largest possible distance between the two ball bearings. Absolute location indication with an increment number of 32,768 increments per revolution and a maximum of 4,096 revolutions. Storage of motor-specific data in the electronic type label and the programming are important features of this product family. The motor feedback systems certified to SIL2/PL d meet current requirements with regard to safety technology and make the certification process easier.
