L-9517-9417-05-A RTLC20 high accuracy incremental linear scale RTLC20 linear encoder tape scale from Renishaw combines ±5 µm/m accuracy with the ruggedness of stainless steel.

1 L A RTLC20 high accuracy incremental linear scale RTLC20 linear encoder tape scale from Renishaw combines ±5 µm/m accuracy with the ruggedness of stainless steel. Two versions are available; self-adhesive RTLC20-S and RTLC20 for use with the revolutionary track system from Renishaw. Designed for applications that demand high accuracy and an independent expansion coefficient with tape scale convenience, RTLC20-S and RTLC20 are read by Renishaw s compact and reliable VIONiC and TONiC family of readheads. RTLC20-S is laid onto the substrate using its self-adhesive backing tape. A patented 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. RTLC20 (without self-adhesive) is used with. 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 transportation. RTLC20-S and RTLC20 with are suitable for many applications, including FPD manufacturing and inspection machines, P-V manufacturing, linear motors with aluminium substrates, 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. High accuracy (±5 µm/m) scale. Further improvement possible with error correction Compatible with VIONiC and TONiC high-performance readheads RTLC20 scale expands at its own low thermal coefficient (10.1 ±0.2 µm/m/ 20 C) Use with for very low hysteresis guide rails are pre aligned in reels for cut to suit flexibility Quick installation. adds fast scale replacement capability Scale can be locked to the substrate at a single datum point anywhere along the axis RTLC20 scale can bridge gaps in the up to 25 mm High solvent immunity
