Use this information to plan your Linear Encoder installation.• Mount the linear encoders close to machine guide ways to ensuresystem accuracy.• One side of the linear encoder addresses flush mounting surfaces,and the opposite side addresses offset mounting surfaces.• If space between the reading head and the mounting surfaceexceeds .18”, use a spacer or mounting bracket to reduce space.• ACU-RITE bracket kit instructions provide step by step installationproceedures.• Tolerances of .010” TIR apply to all mounting dimensions.• Center support mounting surface required for 24” through 60”linear encoder measuring lengths mounted without a spar.• Allow clearance for alignment bracket removal.• Alignment brackets must not be removed until instructed.• Use reading head leveling set screws when surfaces are not flush.• Reading head bracket required for a space >.18”.ACU-RITE ® 4Mounting Information ENC150Scale caseFlushmountingOffsetmountingBackup sparmounting-A- = Machine TravelReading headBEqual Equal1.826 ±.010 [46.5]// .010 A// .010 A// .010 B// .010 A// .010 A0.0 ± .010Move bracket pastthe cable strain reliefAlignment bracket removal clearance1.0[25mm]1.38[35mm]AlignmentbracketAlignmentbracket
