Specifications

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 lenghts shown on this page are typical
to the trim length requirement of the 1” long fastener supplied.
• The 8-32 SHCS for mounting the reading head is a standard low
head style fastener.
• Mounting surfaces are offset.
