Reliability
In addition to the absolute maximum specifications
of codewheels, the environment characteristics of the
application are also important. For example, consistent,
large temperature swings over the life of the product
will affect the codewheel performance characteristics
depending on the material. The following reliability ta-
ble shows results of lifetests under varying conditions
of temperature and humidity.
