Two and Three Channel
Codewheels for Use with Agilent
Optical Encoder Modules
Technical Data
HEDS-51X0/61X0 Series
HEDG-512X/612X Series
HEDM-512X/61XX Series
Features:
• Codewheels Available in
Glass, Film, and Metal
• Available in Two Standard
Diameters
• Cost Effective
• Resolutions from 96 CPR to
2048 CPR
• For Use with HEDS-90XX/
91XX Series Two and Three
Channel Encoders
Description
Agilent Technologies offers a
wide variety of codewheels for
use with Agilent’s HEDS-9000,
HEDS-9100, HEDS-9040, and
HEDS-9140 series Encoder
Modules. Designed for many
environments, applications, and
budgets, Agilent codewheels are
available in Glass, Film, and
Metal. These codewheels are
available in resolutions from 96
Counts Per Revolution (CPR) to
1024 CPR on an 11 mm optical
radius and 500 to 2048 CPR on a
23.36 mm optical radius.
Each of the three codewheel
materials offers a certain
advantage. Metal codewheels are
the most versatile, with a tem-
perature rating up to 100°C,
resolution to 512 CPR (28 mm
diameter), as well as 2 and 3
channel outputs. Film codewheels
offer higher resolution (up to
1024 CPR on a 28 mm diameter)
with an operating temperature of
70°C. Glass codewheels combine
the best of film and metal, offer-
ing a temperature rating of 100°C
and resolutions to 1024 CPR on a
28 mm diameter.
In addition, each material offers a
specific reliability rating. It is
important to consider the specific
application operating environ-
ment, long term operating
conditions, and temperature
ranges when choosing a code-
wheel material.
