Notes:
1. Post(s) can be omitted for keying pur-
poses. Specify the desired post(s) to
be omitted using the figure to identify
Post No. 1.
2. Peg holes are not required in
PC Boards when headers without pegs
are used.
3. One peg only on a 2 position header,
other position sizes have two pegs.
4. Headers with .00015 [0.00038] gold
plated post are available upon request.
Minimums may apply.
5. To determine header overall length
(Dim. A), multiply .156 x the number of
posts. Example: .156 x 10 posts equals
1.560 inches [39.62 mm].

For polarizing purposes only
use connectors without a lock-
