Renishaw: RTLA-S stainless steel linear scale A-9763-1000

RTLA absolute linear encoder tape scale from Renishaw combines ±5 µm/m accuracy with the ruggedness of stainless steel. Two versions are available: self-adhesive RTLA-S and RTLA for use with the revolutionary FASTRACK ™ track system from Renishaw.

Designed for applications that demand high-accuracy and an independent expansion coefficient with tape scale convenience, RTLA-S and RTLA are read by Renishaw’s ground-breaking RESOLUTE™ absolute readhead. 1 nm resolution, 100 m/s maximum speed, ultra-low SDE and jitter result in a linear encoder system that outperforms any other encoder in its class

RTLA-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.

RTLA (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 transportation. RTLA-S and RTLA with FASTRACK are suitable for many applications, including FPD manufacturing and inspection machines, P-V manufacturing, linear motors with aluminum 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

Features

• High accuracy (±5 µm/m) absolute scale. Further improvement possible with error correction • Compatible with RESOLUTE absolute readheads • RTLA scale expands at its own low thermal coefficient (10.1 ±0.2 µm/m/°C @ 20 °C) • Use with FASTRACK for very low hysteresis • FASTRACK guide rails are pre-aligned in reels for cut-to-suit flexibility • Quick installation. FASTRACK adds fast scale replacement capability • Scale can be locked to the substrate at a single datum point anywhere along the axis • RTLA scale can bridge gaps in the FASTRACK of up to 25 mm • High solvent immunity
