In aerospace and defense systems, reliable signal and power connectivity is non-negotiable. The AERO MS27467T25B35PB is a high-density circular connector designed to meet the rigorous demands of avionics, satellite platforms, and space applications where failure is not an option. Its robust construction ensures uninterrupted performance even under extreme vibration, temperature fluctuations, and exposure to corrosive environments.
This connector features a 128-position configuration that maximizes signal density within a compact form factor, making it ideal for modern avionics systems where space is at a premium. The bayonet coupling mechanism provides quick, secure mating with audible confirmation, while the crimp termination method ensures excellent electrical continuity and mechanical strength. Built to military specifications, it undergoes rigorous testing to withstand the harshest operational conditions encountered in aerospace and defense missions.

Military-Grade Reliability & Performance
Qualified to MIL-DTL-38999 Revision N, the MS27467T25B35PB passes the full qualification matrix: 500-hour salt spray, five-cycle thermal shock from −65°C to +200°C, 100g mechanical shock, random vibration per MIL-STD-810, and 1,500 VRMS dielectric withstanding voltage at sea level. The scoop-proof shell prevents contact damage during misaligned mating — critical in confined airframe bays and vehicle wiring compartments. Integral EMI grounding fingers provide 50 dB shielding attenuation from 100 MHz to 10 GHz, meeting the EMC requirements of radar, electronic warfare, and encrypted communications platforms. Individual contact grommet seals combined with a fluorinated silicone interfacial seal deliver IP67-equivalent protection against moisture, hydraulic fluids, and fuel vapors throughout the operational life of the harness assembly.
Supply Chain & Quality Assurance

Full interoperability with equivalent parts from Amphenol Aerospace (LJT06), TE Deutsch (DJT6), ITT Cannon (KJL6), Souriau (8LT5), and Glenair enables cross-sourcing flexibility critical for defense program supply chain resilience. Our inventory is sourced through authorized distribution channels with full traceability: certificates of conformance, lot traveler records, and test reports are available to support AS9100 and AS6081 counterfeit avoidance requirements. Incoming inspection includes visual examination, dimensional verification, and electrical continuity testing prior to shipment on every order.
Selection Guide & Application Notes
The MS27467T25B35PB is the Shell Size 25, insert 35, polarizing position B variant of the MS27467 Series I plug family. A strain relief backshell per SAE-AS85049 is mandatory for all cable terminations; EMI backshells are recommended for radar and EW environments. Mating receptacles must share the same shell size, insert arrangement, and polarizing position — compatible types include MS27466T25B35S, MS27496T25B35S, and MS27656T25B35S. For lower contact count requirements, the MS27467 family spans shell sizes 9 through 23 with a full range of insert arrangements. For superior vibration resistance in high-g airframe locations, consider the MIL-DTL-38999 Series III equivalent with triple-start threaded coupling.
FAQ
What does each code in MS27467T25B35PB mean?
MS27467 = MIL-DTL-38999 Series I straight plug; T = Class T (aluminum, electroless nickel); 25 = Shell Size 25; B = Polarizing position B; 35 = Insert arrangement 25-35 (128 contacts); P = Crimp pin; B = Contact sub-variant. Each field is standardized across all QPL-qualified manufacturers.
How many contacts does this connector support?
128 size #20 crimp pin contacts per insert arrangement 25-35. Size #20 contacts suit AWG 20–24 wire and are rated for 500 mating cycles with gold-over-nickel finish per SAE-AS39029.
Which receptacles mate with the MS27467T25B35PB?
Any MIL-DTL-38999 Series I receptacle in Shell Size 25, insert 35, polarizing position B — including MS27466T25B35S, MS27496T25B35S, MS27505T25B35S, MS27468T25B35S, and MS27656T25B35S, plus equivalent parts from Amphenol, Souriau, Glenair, ITT Cannon, and TE Deutsch.
Is a backshell required?
Yes. SAE-AS85049-compliant strain relief backshell is mandatory per MIL-DTL-38999. For EMI-sensitive platforms, an EMI backshell with 360° cable shield clamp is strongly recommended to maintain the 50 dB shielding rating through the cable termination zone.
How does Series I differ from Series III?
Series I uses a bayonet coupling (quarter-turn, fast mate/demate); Series III uses a triple-start thread (one full turn, higher vibration resistance). Series I suits applications needing rapid field connection; Series III is preferred for high-vibration airframe locations with stringent EMC requirements. Both use identical contacts and insert arrangements.
What does Class T finish mean for corrosion resistance?
Class T specifies an aluminum alloy shell with electroless nickel plating, qualified to 500-hour salt spray per ASTM B117. Suitable for most airborne and ground-based environments. For shipboard or coastal applications demanding higher corrosion resistance, Class E (olive drab cadmium) or Class Z (black zinc nickel) are drop-in alternatives.
