rated to 7.5 amperes per contact. GMCT Series crimp contacts

are qualified to SAE AS 39029.
A wide array of mounting, locking, shrouding and polarizing
accessories is available for this series. For details, see the
Heavy-Duty Rectangular Connector Accessories section.
Due to its many termination styles, its wide range of contact
variants, and an array of cable support accessories, GMCT
Series connectors are widely utilized in navigational systems,

CONNECTOR COMPONENT DESCRIPTION AND TERMINOLOGY
A - Male and female contacts, size 16 and size 20. Power, signal
and shielded. Terminations are crimp, solder cup, printed
board straight solder and press-fit.
B1 - Unloaded connector insulators, male and female. Insulator
retention system retains all contact termination types.
Insulator may be used as a free or fixed connector.
B2 - Loaded connector insulators, male and female. Insulators
may be preloaded per customer requirements with contacts
having terminations of 90° or straight solder printed board
mount, and press-fit. Insulator contact positions may be
selectively loaded with contacts. Unloaded insulator contact
positions remain unloaded and reserved for future use.
Connectors are normally fixed panel or printed board
connectors.
C1 - Polarizing guides, male and female, ensure correct alignmentand coupling of male and female connectors. They may
also be used for keying when used in corner positions ofconnector variants 34, 42, 50, 60, 66, 75 and 104 poles.
C2 - Fixed jackscrews are the stationary threaded members of
the jackscrew system. Threaded pilots and sockets of thejackscrew system also provide connector polarization toensure correct connector coupling.
C3 - Long turnable jackscrews, the rotating threaded members of
the jackscrew system, are used with a free connector having
a hood for cable support. Used on connector variants 9, 14,
18, 20, 21, 26 and 41 poles. Knobs, C-12, may be affixed toturnable jackscrews using either roll pins or set screws.
C4 - Short turnable jackscrews are used to polarize andmechanically assist with the coupling of the male and female
connectors when the free connector is not equipped with ahood.

C5 - Long turnable jackscrews, factory assembled to hood (cable
adapter) for polarization and mechanical assistance in the
coupling of the free connector to the fixed connector. Usedon connector variants with 34, 42, 50, 60, 66, 75 and 104
poles.
C6 - Vibration locking system consists of lock tabs on fixed
connector and locking levers on free cable connectors.
Normally used on connector variants 7, 9, 14, 18, 20, 21 and26 poles. Locks connectors in coupled position.
C7 - Hoods (cable adapters) are used on the free connector toprovide cable support and contact protection. May alsomechanically support either the turnable or fixed membersof the jackscrew system.
C8 - Side access hoods (cable adapters). Extra strength, quickcable assembly to connector, fixed or free, to provide cable
support and relieve stress on contact termination. Suppliedwith both turnable and fixed jackscrew systems.
C9 - Shells (shrouds), both male and female, protect maleand female contacts from damage. Also used to provide
additional polarization combinations.
C10 - Mounting plates, with or without float bushings, provide astronger mechanical method of mounting the fixed connector
to a panel. May be used with shells.
C11 - Mounting angle brackets provide a means of mechanicallyaffixing the fixed connector to the printed board.
C12 - Knobs of turnable jackscrews may be affixed to thejackscrews by using either the roll pin or set screw method.
Specify method desired in step 9 of order numberingsystem.

All contacts of the GMCT series connector family utilize the“Large Surface Area (L.S.A.) Contact Mating System.” The“L.S.A. Contact Mating System” insures the lowest level ofcontact resistance during mechanical endurance tests of 1000
coupling cycles or more. Contact insertion/withdrawal forces
remain substantially the same during the life of the connector.
† The GMCT series uses only “Closed Entry” design female
contacts. The “Closed Entry” design prevents probe damage
to the female contacts, and will not allow the female contact
to accept misaligned or bent male contacts.
† All GMCT series contacts are precision machined from solid,
copper alloy barstock. They are durable, smooth in construc-

tion, and have greater amperage capacities than hollow, sheet
metal style contacts. This is graphically illustrated by theamperage-temperature rise curves developed for the 34 pole
GMCT insulator using 16 AWG [1.5 mm2] wire [see diagram
page 10]. The precision machined, removable contact also
has a more durable insulator retention system than the hollow,
sheet metal style contact. After ten removal cycles from its
insulator, the precision machined contact will withstand axial
forces in excess of 20 lbs. [89N]. In comparison, the hollow,
sheet metal style contact is limited to 10 lbs. [44.5N] after ten
removal cycles from its insulator retention system.

Take Care Not To: - Damage or remove strands.
- Untwist or overtwist strands.
- Leave insulation particles on strands.
- Damage insulation.

Step 2: Crimp wire to contact.
For Hand Crimp Tool: - Place contact into crimping tool.
- Insert wire into contact.
- Center contact by slowly closing thecrimping tool until the crimp indentersmake contact with the crimp barrel.
- Complete the cycle of the crimping tool in
one smooth motion.
- Remove the crimped contact.

An easy-to-use contact insertion tool for 14 AWG [2.5 mm2]
and smaller wires. See photographic demonstration shown
below for recommended insertion procedure.

The spring loaded contact extraction tool simplifies theextraction of removable contacts from the connector insulators. Simply insert the hollow tool tip over the male or female
contact from the front face of the insulator, rotate the toolslightly while increasing the pushing force against the buttof the extraction tool. The contact will be released from theinsulator retention system and “pop out” of the rear face of
the insulator. See photo below for recommended removal
procedure.

Polarization is accomplished with shells bya pin and slot arrangement. Female shells are
slotted to accept non-magnetic stainless steel
polarizing pins mounted on the male shells.
There are 7 polarizing positions available
which are designated by the letters A, B, C, D, E,
F or G. Nonpolarized shells are designated by“O” and are supplied without slot and pin. Seeordering chart.

GROUNDING PLATESDESIGNED FOR
AIRCRAFT APPLICATIONS

Positronic Industries’ grounding plates were designed
especially for aircraft applications where shielded cablemust be grounded to the aircraft frame. The ground wiresof the shielded cable are piggy-backed out of the cable withferrules and are crimped to Size 16 female contacts. The
female contacts are loaded into standard 14 or 34 contact
connector housings. These connectors can then be mated to
the grounding plate which is fastened to the aircraft frame.
Grounding plates have Size 16 precision-machined malecontacts which are swaged and soldered onto the metal

Positronic Industries

plate. The metal plates (angled and plane) have fixed female
jackscrews that accept the rotating jackscrews, which are an
integral part of the mating female connector. Long rotating
jackscrews extend beyond the edge of the cable adapter ofthe 14-contact female connector which permits easy coupling
to the grounding plate.
Other contact variants are available for grounding plate
applications. Contact Technical Sales for information on theavailability of other grounding plates offered by Positronic
Industries.
