Material and Finish
Housing — UL94V-0 rated, nylon,
black
Contacts — High conductivity copper
alloy, post tin plated
For mateability options, see
matrix on page 54.
For strain relief and dust
covers, see pages 40
and 41.
For mating half visuals, see
pages 46 thru 48 and 50,
52 and 53, (49 and 51 Front
Bend Headers only). Mates
with tin-plated square posts
only.
Refer to pages 70 thru 74
for approved wire listing.
Note: 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 above 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 10-position
closed end connector with
locking ramp and without
polarizing tabs for 18 AWG
wire would be:
Base number 644329 plus
prefix-and-suffix
1- — -0
The correct ordering number is
1-644329-0
