Heidenhain AMO – Absolute Angle Measuring Inductive Encoders

Absolute Angle Measuring Encoders
Absolute AMO – Angle measuring encoders are available for both Inside and Outside Diameter Ring Scale scanning, based on our Inductive measuring principle.
WMFA / WMRA – Measuring Flange with Ring Scale or Ring Scale
Standard diameters from 80mm to 652mm are currently available with non-standard sizes possible.  Measurement accuracy in classes as follows: ±3µm, ±5μm or ±10μm arc length.
WMKA – Encoder Head
Our encoder heads have a high degree of protection IP 67 rating with immunity to contamination. Available system resolutions: 1 or 0.25 micron arc length.
Absolute interfaces are available:
  • EnDat
  • Fanuc Interface
  • Mitsubishi
  • BiSS/C
  • SSI + 1Vpp
Typical Applications
  • Direct Drive Torque Motors
  • Rotary and Tilt axes (Pan and Tilt Camera and/or Azimuth and Elevation)
