It is important to consider the
environment in which the
codewheels will be used when
selecting a codewheel material. In
brief, metal codewheels are
Recommended Operating Conditions
Note: Agilent Encoder Modules are guaranteed to 100 kHz, but can operate at higher frequencies. See Encoder Module Data Sheet for
specifications and output load recommendations.
*HEDM-6140 is guaranteed to 100 kHz with the HEDS-9040 #T00 module.

codewheels offer both high
temperature and higher
resolution, but are also more
expensive. Consider the following
