Connector Ordering
Information
The “Base Part Numbers”
Chart at right shows the
base part number and num-
ber of circuits available for
the described connectors.
Prefixes and suffixes are
determined by the number
of circuit positions in the
connector. For example, the
complete part number for a
10-position feed-thru con-
nector with locking ramp
and without polarizing tabs
for 18 AWG wire would be:
Base number 640599 plus
prefix-and-suffix
1- -0
The correct ordering number
is
1-640599-0
The set of numbers in bold
face are the RoHS equiva-
lent version of the standard
product. Example:
