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.
L ≤ 100 mm Single reference mark at scale centre
L > 100 mm Reference marks at 50 mm spacing (first reference mark 50 mm from scale end)
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
('RKLC40-S scale installation drawing', page 4)
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
