3-644043-4 Datasheet, PDF (51/84 Pages) Tyco Electronics – MTA, CST-100 II, SL-156 and AMP Economy Power

MTA, CST-100 II, SL-156 and
AMP Economy Power (EP) Connectors
MTA-156 Polarized Lock Headers—Right-Angle
Material and Finish
Housing — UL94V-0 rated, polyester,
white
Posts — Copper alloy, tin plated or
.000030 [0.00076] gold over nickel
Notes:
1. Post(s) can be omitted for keying
purposes. 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 mateability options, see
matrix on pages 34, 35, 54
and 58.
For mating half visuals, use
only connectors with a locking
ramp for polarization/retention
purposes, see pages 36 thru
39, 55, 60 and 62.
For polarizing purposes only
use connectors without a lock-
ing ramp. See pages 36 thru
39, 60 and 62.
Header Ordering
Information
The “Base Part Numbers”
Chart at right shows the base
part number and number of
posts available for the
described headers.
Prefixes and suffixes are deter-
mined by the number of post
positions in the header. For
example, the complete part
number for a 10-position
header with front bend and
with pegs would be:
Base number 644617 plus
prefix-and-suffix
4- — -0
The correct ordering number is
4-644617-0
