Connector Ordering
Information
The “Base Part Numbers” Chart
at right shows the base part
number and number of circuits
available for the described
connectors.
Prefixes and suffixes are deter-
mined by the number of circuit
positions in the connector. For
example, the complete part
number for a 12-position
closed end connector for
18 AWG wire would be:
Base number 641435 plus
prefix-and-suffix
1- — -2
The correct ordering number is
1-641435-2
See page 15 for an explanation of
RoHS lead free equivalents.
Note: All RoHS equivalent part
numbers may not be available upon
catalog release. If the number you
need is not available, please contact
Product Engineering to expedite
your request.
