page 45.
2. Refer to pages 70 thru 74 for
approved wire listing.
3. For strain reliefs and dust covers,
see pages 40 and 41.
4. For keying plugs and panel
mount end caps, see page 42.
5. Other circuit sizes are available

may apply.
6. Connector circuits can be
molded closed for keying pur-
poses. Minimums may apply.
7. Where no part numbers appear
in the chart, parts can be made
available upon request.
Minimums may apply.
8. To determine connector overall
length (Dim. A), multiply .156 x
the number of circuits. Example:
.156 x 10 circuits equals 1.560
inches [39.62 mm].

Connector Ordering
Information
The “Base Part Numbers”
Chart at right shows the
base part number and
number of circuits available
for the described connec-
tors.
Prefixes and suffixes are
determined by the number
of circuit positions in the
connector. For example, the
complete part number for a
10-position closed end con-
nector with locking ramp
and without polarizing tabs
for 18 AWG wire would be:
Base number 640426 plus
prefix-and-suffix
1- — -0
The correct ordering number
is
1-640426-0
The set of numbers in bold
face are the RoHS equiva-
lent version of the standard
product. Example:
