The AERO MS27473T22F35P is a Shell Size 22, MIL-DTL-38999 Series II straight bayonet plug configured with insert arrangement 22-35 for 100 size #20 crimp pin contacts in polarizing position F. Class T construction — aluminum alloy with electroless nickel — delivers 500-hour salt spray resistance and an operating range of −65°C to +175°C in a low-profile, lightweight shell optimized for avionics and satellite wiring applications. The three-point bayonet coupling mates in a single quick-disconnect motion, making it the preferred choice over Series III threaded alternatives in avionic line-replaceable unit (LRU) interfaces where rapid field swap-out is a maintenance requirement.

Military-Grade Reliability & Performance
Built to MIL-DTL-38999 Revision N under Aero-Electric’s ISO 9001:2015 and AS9100:2016 certified manufacturing program, the MS27473T22F35P delivers the full Series II qualification matrix: 500-hour salt spray, thermal shock across −65°C to +175°C, mechanical shock, vibration per MIL-STD-810, and 1,500 VRMS dielectric withstanding voltage. The Series II low-profile shell design reduces connector mated-pair length versus Series I and Series III equivalents, critical for avionics bays and satellite equipment panels where axial depth is constrained. Integral EMI grounding fingers provide 45dB shielding attenuation across 100MHz to 10GHz, meeting the EMC requirements of avionics data buses and space payload signal chains. Individual contact grommet seals and an interfacial moisture barrier deliver IP67-rated protection against moisture, hydraulic fluids, and aviation fuels throughout service life.

Selection Guide & Application Notes
The MS27473T22F35P is the Shell Size 22, insert 22-35, polarizing position F, Class T (electroless nickel) pin variant. For socket contacts, specify MS27473T22F35S. For temperature requirements above +175°C, Class F (electroless nickel, +200°C) variants are available in the same footprint. Mating receptacles must match shell size 22, insert 35, and polarizing position F — compatible types include MS27472T22F35S (wall mount), MS27484T22F35S (rear wall mount), and MS27497T22F35S (jam nut). A SAE-AS85049 backshell is required for all cable terminations; EMI backshells with 360° cable shield clamp are recommended for avionics and EW applications to maintain full shielding continuity through the cable exit zone.
FAQ
What does each code in MS27473T22F35P mean?
MS27473 = MIL-DTL-38999 Series II straight cable plug; T = Class T (aluminum, electroless nickel); 22 = Shell Size 22; F = Polarizing position F; 35 = Insert arrangement 22-35 (100 contacts); P = Crimp pin contacts.
How many contacts does this connector support?
100 size #20 crimp pin contacts per insert arrangement 22-35, rated for 500 mating cycles per SAE-AS39029. Size #20 contacts are compatible with AWG 20–24 wire with gold-over-nickel mating interface finish.
Which receptacles mate with the MS27473T22F35P?
Any MIL-DTL-38999 Series II receptacle in Shell Size 22, insert 35, polarizing position F — including MS27472T22F35S (wall mount), MS27484T22F35S (rear wall mount), and MS27497T22F35S (jam nut) — from any QPL-qualified manufacturer.
How does Series II differ from Series I and III in avionics applications?
Series II uses a bayonet coupling in a low-profile, lightweight shell — ideal for avionics LRU interfaces and satellite panels where axial depth and weight are constrained. Series I is larger and scoop-proof with higher vibration resistance; Series III uses triple-start threading for superior EMI shielding in high-vibration airframe locations. Series II is preferred when compact size, rapid mating, and moderate vibration resistance are the primary drivers.
What is the temperature rating and how does Class T compare to other finishes?
Class T (electroless nickel) is rated −65°C to +175°C with 500-hour salt spray resistance — suited for most avionics and satellite environments. Class F (electroless nickel, alternate process) extends to +200°C but with lower salt spray endurance. For extreme corrosion environments, consult Aero-Electric for stainless steel shell options.
Is a backshell required, and which type for satellite applications?
A SAE-AS85049 strain relief backshell is mandatory for all cable terminations. For satellite and spacecraft applications, an EMI backshell with 360° cable shield clamp is strongly recommended to maintain the connector’s 45dB shielding rating through the cable exit zone. Low-outgassing backshell materials compliant with NASA outgassing requirements (ASTM E595) should be specified for flight hardware applications.
