3 Channel Encoder for Extremely Small Machines


The IEH3‐4096 series 3 channel encoder delivers two square‐wave signals as well as an additional index channel, a higher resolution, an extended operating temperature range and improved speed control, especially in the low speed range. The encoder increases the length of the motor by just 1.4 mm and can be combined with numerous precious‐metal commutated DC motors of the FAULHABER SR series measuring 15 to 22 mm in diameter. They can be used in equipment technology, such as in measurement devices, for valve adjustment, in camera technology, and in precision optics, for example for mirror positioning or lens or filter adjustment.


  • Operating temperature range: ‐40 to100 °C
  • Resolution: up to 4096 pulses per revolution
  • Mechanically compatible with its predecessor models
