Overview of the FORTiS-S 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.
