To avoid cross-plugging problems in applications requir-
ing the use of more than one connector of the same size
and arrangement, alternate rotations are available as
indicated in the accompanying charts.
As shown in the diagram below, the front face of the pin
insert is rotated within the shell in a clockwise direction
from the normal shell key. The socket insert would be
rotated counter-clockwise the same number of degrees
in respect to the normal shell key.
Position W Position X Position Y Position Z
View looking into front face of pin insert or rear of socket insert.
The following insert arrangements have the
same alternate insert rotations for W, X, Y
and Z, which are:

ACA-B Connectors accessories
crimp and solder contacts
Contacts for ACA-B connectors are machined from copper alloys and silver plated for maximum corrosion
resistance, with a minimum millivolt drop and a maxium current carrying capacity; the size 16 and 12 socket
contacts are of the closed entry design. Gold plated contacts are also available. (See how to order, pg. 39).
Solder contacts for ACA-B connectors are not sold as separate items.
* Solder contacts are not sold as separate items. Part numbers shown here are for cirmp contacts only.
** When using wire adapter sleeve shown.
*** Contact ratings as stated are test ratings only. The connector may not withstand full rated current through all
contacts continuously. Please note that the electrical data given is not an establishment of electrical safety factors.
This is left entirely in the designer’s hands as he can best determine which peak voltage, switching surges,
transients, etc. can be expected in a particular circuit.

application tools
When proprietary crimp contacts are employed rather than the standard MS
approved solder contacts, the following application tools are recommended for use.
There is a possibility of additional crimping tools other than those included being
available at present or in the future for this specific application.
* Use Daniels Turret TH29-1 or Astro Tool Co. Turret 616266
** For appropriate crimp tool and positioner refer to Pico Crimping Tool Co.
