Overview of the FORTiS-N FS encoder
system
This system is an enclosed linear optical encoder designed for use in harsh industrial environments
where high-precision feedback and metrology are required. Based upon Renishaw's award-winning
absolute technology, the rugged non-contact design has no internal moving parts, such as bearings
or wheeled readhead carriages, thus improving the overall reliability. Additionally, hysteresis and
backlash errors associated with mechanical contact system designs are reduced.
In addition to enhanced breakage resistance, the robust steel scale has a coefficient of thermal
expansion similar to the base material used in the majority of machines, reducing errors due to
thermal effects whilst increasing measurement certainty.
Renishaw's patented set‑up LED provides instant verification of the encoder's signal strength
and therefore its accurate alignment. This intuitive procedure eliminates the need for additional
peripheral diagnostics equipment during installation. When combined with Renishaw's carefully
designed installation accessories, these unique tools make installation easier and faster compared
to traditional methods, whilst building confidence in a right‑first‑time installation.
