MTA, CST-100 II and SL-156 Connectors

MTA-156 Friction Lock High Temperature Headers—Straight

Material and Finish

Housing—UL94V-0 rated, nylon, black

Posts—Copper alloy, tin plated .000015

[0.00038] gold over nickel

Temperature—Maximum Temperature

Rating: 280°C

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. Gold headers are duplex plated, gold on mating

end of post and tin-lead on the solder tail.

3. Headers with straight and right-angle square posts

are available upon request. Minimums may apply.

4. To determine header overall length (Dim. A), mul-

tiply .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 27, 28, and 47.

For mating half visuals, use only connec-

tors with a locking ramp for polarization/

retention purposes, see pages 29 thru 32,

53 and 55.

For polarizing purposes only use connec-

tors without a locking ramp. See pages

29 thru 32, 49 and 51.

Header Ordering Information

The “Base Part Numbers” Chart at right

shows the base part number and num-

ber of posts available for the described

headers.

Prefixes and suffixes are determined

by the number of post positions in the

header. For example, the complete part

number for a 10-position header with

round tin plated posts::

Base number

647648 plus

prefix-and-suffix

4- — -0

The correct ordering number is

4-647648-0

All part numbers in
