see pages 5 through 8.
For mateability options, see
matrixes on page 4.
Note: To determine header overall
length (dim. A), multiply .050
x the number of circuits and
add .150. Example: .050 x 6
circuits equals .300 + .150 =
.450 [11.43].

Header Ordering Information
Base part number prefixes
and suffixes indicate the
number of circuit positions,
for example: Base part num-
ber 1445121
2 position = 0-1445121-2
and
28 position = 2-1445121-8
