QUANTiC™ encoder series
The QUANTiC encoder system integrates Renishaw's filtering optics design and interpolation technology to create a high performance, super-compact, digital all-in-one incremental open optical encoder. QUANTiC encoders are easy to install with exceptionally wide installation and running tolerances, along with built-in installation and calibration functions.
QUANTiC readheads are compatible with linear, partial arc and rotary scales.
More detailed diagnostic information can be accessed by using the Advanced Diagnostic Tool ADTi‑100 and ADT View software during installation or for in-field diagnostics and fault finding.
In-built reliability and ease of installation
Robust position measurement over contamination
QUANTiC readheads ensure excellent motion control performance in a wide range of applications by minimising positional error over scale contamination. A new detector design provides an additional layer of signal filtering which helps to eliminate non-harmonic signal frequencies, ensuring low Sub-Divisional Error (SDE) and minimal signal variation over dirt or contamination on the scale.
Increased operating tolerances whilst maintaining metrology
The new detector design helps to increase installation and operational tolerances whilst maintaining metrological performance. Combining this with Renishaw's established filtering optics and signal processing technology makes QUANTiC a robust and easy to use incremental digital quadrature encoder.

Scale options
- Linear scales are used where straight-line position information is needed - usually X, Y or Z axes.
- Rotary scales are used for angular position information and the motion control of rotating elements.
- Partial arc scales are used for measuring a partial arc of rotation by wrapping them around drums, shafts or arcs.
