The scale and end clamps must be installed following the installation process, see
TONiC RKLC20-S linear installation guide
0.15 mm × 6 mm including adhesive
20 µm
±5 µm/m
±2.5 µm/m achievable with two point error correction
20 mm up to 20 m (> 20 m on request)
Hardened and tempered martensitic stainless steel fitted with a self‑adhesive backing tape
4.6 g/m
Matches that of substrate material when scale ends fixed by epoxy mounted end clamps
+10 °C to + 35 °C
Epoxy mounted end clamps (A-9523-4015)
Approved epoxy adhesive (A-9531-0342)
Scale end movement typically < 1 μm*
Customer selected IN-TRAC reference mark, directly embedded into incremental track.
Bi-directional position repeatability
Single reference mark selection by selector magnet (A-9653-0143) customer positioned.
Unit of resolution repeatability (bi-directional) across full system rated speed and temperature ranges
Magnetic actuators; with dimple triggers Q limit, without dimple triggers P limit
('RKLC20-S scale installation drawing', page 5)
The limit output is nominally asserted when the readhead limit switch sensor passes the limit
magnet leading edge, but can trigger up to 3 mm before that edge
Customer placed at desired locations
< 0.1 mm
