TX Series • MIL-DTL-38999 Series III Style Connectors

Performance Specifications

Built to meet or exceed MIL-DTL-38999 specifications Guaranteed fully compatible and interchangeable with respect to physical and performance characteristics with all existing MIL-DTL-38999 Series III commercial,

military, NASA, ESA (European Space Agency) derivatives

Environmental Characteristics

T emperature Range

-67° to +392°F (-55° to +200°C)

Service life varies with the maximum internal hot spot temperature resulting from any combination of electrical load or ambient temperature: 77°F (25°C): Continuous 221°F (105°C): 45,000 hours 392°F (200°C): 1,000 hours Water Pressure

IP67 rating (environmental sealing) when used in conjunction with proper sealing accessories

Fully submersible to 3.3 ft (1m) for minimum of 30 min Air Leakage Rate Environmental

Air leakage not to exceed 1 inch 3/hr (4.55 x10-3 cm 3/sec) at 30 psi (2.11 kg/cm 2) pressure differential with all contact cavities filled Hermetic

Helium leakage not to exceed 0.01 micron per ft 3/hr (1.0 x 10-6 cc 3/sec) at 15 psi (1.1 kg/cm 2)

Hermetic inserts rated up to 14,000 psi (984 kg/cm 2) when precision welded or solder mounted Thermal Vacuum Outgassing

Outgassed at high vacuum (5 x 10-5 torr) for 48 hours at 350°F (176°C); components shall not release greater than 1.0% total mass loss (TML) and

0.1% collected volatile condensable material (CVCM) Salt Spray Rating

See Materials & Finishes, p. B-16 Humidity

Mated connectors shall maintain an insulation

resistance of 100 megohms or greater at 77°F (25°C) with 95% humidity for duration of 20 days Chemical Resistance to Fluids

20-hour full immersion (unmated) in hydraulic fluid and lubricating oil without damage or material degradation Lightning Strike Resistance

Per EIA/ECA-364-75, mated connectors with full wire braid shield assembly will show resistance to indirect lightning strike with the following peak currents (amps): Aluminum & Stainless Steel Shells: 10,000A

Composite Shells: 6,000A (3,000A, shell size 9 only)

Physical Characteristics

Coupling

Coupling is achieved by one 360° clockwise turn of the coupling ring, triple-start metric stub thread design, with integrated self-locking ratchet mechanism Scoop-Proof

Shell design is 100% scoop-proof to prevent contact raking in blind-mate applications Coupling T orque

Engagement & Disengagement Force (max / min)

Shell Size 9: .67 ft-lb f (.904 N-m) / .08 ft-lb f (.113 N-m) Shell Size 11: .83 ft-lb f (1.13 N-m) / .08 ft-lb f (.113 N-m) Shell Size 13: 1.17 ft-lb f (1.58 N-m) / .17 ft-lb f (.226 N-m) Shell Size 15: 1.42 ft-lb f (1.92 N-m) / .33 ft-lb f (.452 N-m) Shell Size 17: 1.92 ft-lb f (2.60 N-m) / .33 ft-lb f (.452N-m) Shell Size 19: 2.17 ft-lb f (2.94 N-m) / .33 ft-lb f (.452 N-m) Shell Size 21: 2.58 ft-lb f (3.50 N-m) / .50 ft-lb f (.678 N-m) Shell Size 23: 3.16 ft-lb f (4.29 N-m) / .58 ft-lb f (.791N-m) Shell Size 25: 3.16 ft-lb f (4.29 N-m) / .58 ft-lb f (.791 N-m) Polarization

Single master key and keyway on top position of shell Four minor keys and keyways on shell Insert Arrangements

63 standard, custom inserts available Alternate Keying

Normal polarization (N), plus 5 alternate shell keying

polarizations (A, B, C, D, E)

Endurance Characteristics

Coupling Cycles

500 coupling cycles (minimum) Shock

Half-sine wave with 300g’s (±15%) magnitude with duration of 3 milliseconds with less than

1 microsecond maximum discontinuity with no cracking, loosening of parts, or other failures High-Impact Shock

Per MIL -S-901, a 400 lbs (181 kg) hammer dropped onto assembly from height of 1 ft (30 cm), 3 ft (91 cm), and 5 ft (152 cm) applied to connector assembly in 3 axes, totaling 9 impacts, connector assembly experienced less than 1 microsecond maximum discontinuity with no cracking, loosening of parts, or other failures Sine Vibration

Random vibration at 10 to 2,000 Hz (15 g’s) experienced less than 1 microsecond maximum discontinuity with no cracking, loosening of parts, or other failures Random Vibration
