Typical Mounting (s)

 

 

A variety of mounting conditions can be accommodated.

The machine configuration determines the brackets required to install the linear encoder.

Three typical mounting conditions are shown; flush, offset, and backup spar (as shown previously on page 4).

The 8-32 SHCS fastener lengths shown on this page are supplied with the encoder hardware.

The 8-32 SHCS for mounting the reading head is a standard low head style fastener.

Flush surfaces

Offset surfaces

1/4-20 x 1” BHCS

with encoder washer

8-32 x 3/4” SHCS

Space of < .18” use reading

head leveling set screws.

Mounting surfaces are offset.

Installation without backup spar.

Use leveling screws in place of spacers or shims.

8-32 x 5/8” SHCS (trim if necessary)

Mounting surfaces are flush within .005”.

The reading head leveling screws are not required.

A space >.18”, use a spacer or bracket (shown); <.18” use leveling set screws.

Flush or offset mounting surfaces with a backup spar.

Bracket used to reduce head to mounting surface gap.
