Does anyone know how to decipher the current date codes stamped on Aerotech
motors? I know about the earlier version, the one in hexadecimal with the year
encoded in the first 2 digits and the month/day in the following 2 or 3 digits.
However at some point they switched to a different code with 6 digits, all
numbers.

Thanks.

Jonathan

Thanks. OMG could they have made it more obscure? What would be so wrong
about just using the date in a straightforward fashion?

As Estes discovered - consumers think the date is an "expiration date"
and not a manufacturing date and they return motors to the store
thinking they are "expired".
