ACU-RITE ENC 150 (Old Style) - Manual (Page 5)

Use this information to plan your Linear Encoder installation.
• Mount the linear encoders close to machine guide ways to ensure
system 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 surface
exceeds .18”, use a spacer or mounting bracket to reduce space.
• ACU-RITE bracket kit instructions provide step by step installation
proceedures.
• 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”.
