Renishaw A-9704 250MM Long Linear Encoder Tape ScaleRTLR40 linear encoder tape scale from Renishaw combines ±15 μm/m accuracy with the ruggedness of stainless steel. Two versions are available: self-adhesive RTLR40-S and RTLR40 for use with the revolutionary FASTRACK™ track system from Renishaw. Designed for applications that demand accuracy and an independent expansion coefficient with tape scale convenience, RTLR40-S and RTLR40 are read by Renishaw’s RGH45 readhead. RGH45 offers resolutions to 0.1 μm, 10 m/s maximum speed, excellent dirt immunity and provides significant motion control performance improvements over magnetic, inductive or coarse-pitch optical encoders.RTLR40-S is laid onto the substrate using its self-adhesive backing tape. An application tool makes this a quick, simple and inexpensive process. A clamp is fitted at a single point to lock the scale to the substrate using fast curing Loctite® adhesive.RTLR40 (without self-adhesive) is used with FASTRACK. In this case, the scale is held securely in place by two miniature, yet rugged, guide rails. Again, the scale is clamped in a single point to allow independent expansion with extremely low hysteresis, even over wide temperature ranges. If damaged, the scale can be pulled out of the guide rails and quickly replaced, even where access is limited, thus reducing machine downtime. This feature also makes the new linear encoder system ideal for large machines that need to be sectioned for transit.RTLR40-S and RTLR40 with FASTRACK are suitable for many applications, including FPD manufacturing and inspection machines, printing machines, linear motors, axes that are exposed to potential damage, large CMMs and other machines that require the scale to be installed/removed for transit, or simply for any application where thermal expansion of the scale must be independent of the machine structure
