Technical Documents
See mating connector for applicable
product and application specifications.
Retention and surface mount fea-
tures available upon request.
Other header sizes can be made
upon request.
*Note: Headers are available in sizes
1 thru 40. When ordering, add the
prefix and/or suffix (dash) numbers
plus 5- -0 to the base part number
that corresponds with the number of
positions per row. For example, the
complete part number for an 8-position
header is 5-146455-8. The complete
part number for a 16-position of the
same series would be 6-146455-6.
