Reference mark

Type Customer selected IN-TRAC reference mark, directly embedded into the incremental track. Bi-directional position repeatability
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)
Selection Customer positioned selector magnet (A-9653-0143) for selecting desired IN-TRAC reference mark
Repeatability Unit of resolution repeatability (bi-directional) across full system rated speed and temperature ranges

Limit switches

Type
Magnetic actuators; with dimple triggers Q limit, without dimple triggers P limit (see
Trigger point 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
Mounting
Customer placed at desired locations
Repeatability < 0.1 mm
