Mounting Information SENC 150
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 procedures.
• 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”.
