Encoders for tomorrow’s medical technology

Encoders from HEIDENHAIN, along with its brands AMO, LTN, NUMERIK JENA, RENCO,and RSF, have proven themselves in medical technology applications for many years. Theirreliability and failsafe performance are key benefits in therapeutic and diagnostic equipment.
An increasingly important factor is also the high accuracy of these rotary, angle, and linear
encoders.

Scale-tape solutions from AMO
Reliable measurement for large medical equipment

Large medical equipment is a valuable investment. requiring safe, reliable, and long-term
operation. Inductive system solutions from AMO are ideal for meeting these demands at
the measurement technology level. Models are available for linear and rotary axes with longmeasuring distances.
For applications such as CT scanners, AMO systems can be ordered with absolute orincremental scanning in custom diameters of up to several meters. The measuring standard
can be configured for radial scanning, with the scanning head mounted on the inside oroutside of the circular axis, or for axial scanning, with the scanning head mounted laterally.
Designers enjoy unparalleled configuration possibilities.

Benefits of AMO encoders
 Custom sizes for long measuring lengths
 Variety of scanning options: incremental/absolute, axial/radial, and internal/external Touchless, wear-free measurement
 Contamination immunity Robust measurement, even within magnetic fields
 Special solutions available for exposure to radiation
