QUANTiC™ encoder series
The QUANTiC encoder system integrates Renishaw's filtering optics design and interpolation technology to create a super-compact, robust, incremental open optical encoder. QUANTiC encoders are easy to use with exceptionally wide installation and operation tolerances, along with built-in calibration functions.
QUANTiC readheads offer digital output and a new analogue output variant with a wide variety of configurations and linear or rotary scale options.
Detailed diagnostic information can be accessed by using the ADTpro-100 standalone encoder diagnostic tool and the ADTi‑100 diagnostic tool, both of which are compatible with the ADT View software. They aid optimisation of encoder installation and in-field fault finding to satisfy the most demanding motion control applications.
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.
Easy installation and set-up
The advanced optical design and signal processing of the QUANTiC encoder provides increased installation and operational tolerances whilst maintaining metrological performance. Low cost of ownership is achieved through reduced installation and set-up times.
Speed
Speeds up to 24 m/s can be achieved to meet the most demanding motion control requirements.

Optional Advanced Diagnostic Tools
The Advanced Diagnostic Tools assist in system set-up and planned maintenance to help minimise unscheduled machine downtime.
The ADTpro-100 is a handheld, standalone encoder diagnostic tool featuring an integral colour touch screen. The ADTpro-100:
- Requires no computer or additional set-up equipment to display comprehensive real-time encoder information.
- Is easy and intuitive to use with plug-and-play functionality to aid system set-up and calibration.
- Interfaces with the optional ADT View computer software, which allows encoder data to be saved as a record of the system setup and performance. ADT View can also be used to update the ADTpro-100 firmware
The ADTi-100, in conjunction with the intuitive ADT View computer software:
- Provides comprehensive real-time encoder data feedback to aid more challenging installations and diagnostics.
- Assists system set-up, calibration and signal optimisation along the entire axis.
- Allows data, such as signal strength vs position along the axis, to be saved as a record of the system setup and performance.
Both the ADTpro-100 and ADTi-100 are ideal for aiding system optimisation and diagnostics, particularly for installations when the readhead LED is not visible. They can be used standalone or in-line, connected between the readhead and the controller as part of the control loop.
