DESCRIPTION
The Series 63A is intended for
applications
performance, high-resolution digital
feedback in a very small package.
The Series 63A encoder provides 8-
bit absolute resolution in a package
only 20mm (0.787") in diameter.
Outputs can be configured in either
gray code or binary code. The
encoder housing is constructed of a
conductive carbon fiber composite
that provides the EMI shielding of an
allmetalhousingandtheperformance
of a lightweight robust assembly.
APPLICATIONS
• Steer by Wire
• Machine Tool Controls
• Material Handling
• Flow Meters
• Any Application Requiring
Discrete Digital Positioning and
Angular Detection at Start Up.

Output Format:
Gray code or Binary Code: 8-bit, single turn,
single ended. Gray code option utilizes low
true Chip Enable (CE’) that is pulled down with
internal 10K resistor. Positive TTL signal to
CE’ will force the 8-bit outputs to tri-state
condition allowing for shared data paths
