A variety of mounting conditions can be accommodated.• The machine configuration determines the brackets required toinstall the linear encoder.• Three typical mounting conditions are shown; flush, offset, andbackup spar (as shown previously on page 4).• The 8-32 SHCS fastener lenghts shown on this page are typicalto the trim length requirement of the 1” long fastener supplied.• The 8-32 SHCS for mounting the reading head is a standard lowhead style fastener.• Mounting surfaces are offset.• Installation without backup spar.• Use leveling screws in place of spacers or shims.• Mounting surfaces are flush within .005”.• The reading head leveling screws are not required.• Flush or offset mounting surfaces with a backup spar.• Bracket used to reduce head to mounting surface gap.• Use reading head leveling set screws.ACU-RITE ® 8Typical Mounting (s) ENC 150Backup spar withbracketOffset surfaces1/4-20 x 1” BHCSand encoder washer8-32 x 3/4” SHCS (trim)Flush surfaces.0050.0 ± .0051/4-20 x 1” BHCSwith encoder washer8-32 x 1” SHCSSpace of < .18” use reading headleveling set screws.1/4-20 x 1/2” BHCSand spar washer8-32 x 5/8” SHCS(trim)1/4-20 x 1/2” BHCSand washerA space >.18”, use a spacer orbracket (shown); <.18” useleveling set screws.
