Specification for HexaShield Adapters
for Circular Connectors
1.0 Introduction
1.1 Scope
This specification covers accessories for use with electrical connectors under
non-environmental conditions, and for suppression of radio frequency and
electromagnetic interference. Unless otherwise specified, it refers to the
SAE-AS85049 for category 3C.
1.2 Description
The HexaShield™ adapters covered by this specification are used to terminate
individual shields of a cable bundle. As an option, an overbraid can be terminated as
well to the same adapter.
1.3 These adapters are designed to be mounted on circular Military Specification
connectors.
1.4 Temperature range: -65ºC to +175ºC (with silver-plated copper braid).
-65ºC to +150ºC (with tin-plated copper braid).
2.0 Requirements
2.1 Materials
2.1.1 Adapter shell: Aluminum Alloy
2.1.2 Ferrule: Copper Alloy
2.1.3 Solder Shield: Copper Braid tinned with Sn96 per ANSI J-STD-006.
2.1.4 Plating: Electroless Nickel conforming to SAE AMS-C-26074,
or Cadmium Olive Drab per SAE AMS-QQ-P-416
over a suitable underplate.
2.2 Performance Requirements
2.2.1 Visual Examination
HexaShield™ adapter shall be examined visually to ensure conformance with
Specification Control Drawing.

2.2.2 Temperature Cycling
Test in accordance with MIL-STD-1344, method 1003. 5 cycles with -65ºC to
+175ºC (Silver plated copper braid) or to +150ºC (Tin plated copper braid). After
conditioning, HexaShield™ adapters shall meet the subsequent performance
requirements specified in Table 1 and shall show no evidence of damage detrimental
to performance or handling.
2.2.3 Temperature Life
HexaShield™ adapters shall be subjected to the following temperature for 1000
hours:
• +175ºC for silver plated copper braid.
• +150ºC for tin plated braid.
After conditioning, HexaShield™ adapters shall meet the subsequent performance
requirements specified in Table 1, and shall show no evidence of damage detrimental
to performance or handling.
2.2.4 Maintenance Aging
Each sample is dismantled and assembled 10 times. The various components of each
adapter can be mixed together during the disassembly. After the test there shall be no
evidence of cracks, breaks or loosening of parts.
2.2.5 Vibration
Test in accordance with MIL-STD-1344, method 2005-1, test condition VI, letter J, 8
hours in each of 3 mutually perpendicular directions. The sample shall be tightened
on a suitable fixture using the recommended coupling torque. The cable shall be
supported 250 mm from the test fixture (see fig.1). Monitoring for discontinuity is
not required. After the test, there shall be no evidence of cracks, breaks or loosening
of parts.
2.2.6 Mechanical Shock
Test in accordance with MIL-STD-1344, method 2004-1, test condition D. Three
shocks in each 6 perpendicular directions. The sample shall be tightened on a
suitable fixture using the recommended coupling torque. The cable shall be supported
250 mm from the test fixture (see fig.1). Monitoring for discontinuity is not required.
After the test, there shall be no evidence of cracks, breaks or loosening of parts.

2.2.7 Cable Pull-Out
Individual ferrules are tested with 4 shielded twisted pairs in accordance with
MIL-STD-1344, method 2009-1, test condition A (3 ferrules min. per HexaShield).
Each ferrule shall not pull-out. During the test, the DC resistance test (paragraph
2.2.9) shall be monitored. DC resistance shall not exceed 7 mohms during the test and
5 mohms after.
2.2.8 Salt Spray-Corrosion
Test in accordance with MIL-STD-1344, method 1001-1, test condition letter B for
nickel plated shell (48 hours without molded part), and test condition C for cadmium
plated shell (96 hours without molded part and 500 hours with molded part). After
the test, HexaShield™ adapters shall show no exposure of basis metal due to
corrosion, which could affect the subsequent performance requirements specified in
Table 1.
2.2.9 DC Resistance
HexaShield™ adapters shall be tested in accordance with MIL-STD-1344 A, method
3004-1 or equivalent test equipment. Test current 1.0 ±0.1 ampere.
Voltmeter probes or four wire connections shall be applied as follows: (see fig. 1).
• Probes between A and B
• Sample DC resistance = R1 - R2
Where R2 shall be the DC resistance of an equivalent length of cable. The DC
resistance shall not exceed 5.0 mohms before or after conditioning.
2.2.10 Post Test Examination
The tested HexaShield™ adapters shall be examined for evidence of cracking,
loosening of parts, or missing parts.
2.2.11 Shielding Effectiveness
HexaShield™ adapter, assembled on to a brass adapter shall be tested in accordance
with method VG95373 Part. 41 and the fig. 2 hereafter. The sample shall be wired
with copper tubes. The minimum shielding effectiveness shall be better than 98dB at
30 Mhz and 90dB at 100 Mhz. Sample description (see fig. 2).
3.0 Quality Assurance Provisions
3.1. Qualification Inspection
It shall consist of all of the applicable examinations and tests performed in the
sequence specified in Table 1.

3.2 Qualification By Similarity
For parts which differ in minor details from those submitted for qualification, the
manufacturer needs only provide inspection and test data to validate the differences.
3.3 Sampling
Samples have been selected in order to be a representative sampling of the
HexaShield™ family for circular connectors. The most unfavorable configurations in
term of weight and size shall be subjected to the qualification.
Sample type
• HexaShield™ adapters with:
Cadmium and nickel plating.
Straight and right angle bodies
SolderShield ferrules
• Cable
Four shielded twisted pairs shall be connected to each SolderShield ferrule.
Shielded twisted pairs shall be as those recommended in the Specification Control
Drawing.
