MS27467T25F37SD: High-Reliability Interconnects for Large-Scale Systems
In the rigorous landscape of aerospace engineering and defense electronics, managing high-density signal pathways across large-scale interfaces requires uncompromising reliability. The MS27467T25F37SD is a premier 37-pin RFI shielded plug, specifically engineered to meet the stringent MIL-DTL-38999 Series I requirements. As a cornerstone of the AVIA Connector specialized inventory, this series ensures consistent performance under extreme physical stress and high-frequency electromagnetic interference.
The MS27467T25F37SD configuration is optimized for Shell Size 25, the largest standard shell in the series, providing a robust platform for 37 independent signal circuits. Its aluminum construction, paired with an electroless nickel finish, makes it a preferred choice for heavy-duty radar arrays, main power distribution units, and tactical communication hubs.

Technical Features of the MS27467T25F37SD Configuration
The design philosophy of the MS27467T25F37SD focuses on safety, durability, and rapid deployment. Featuring a “scoop-proof” shell, this plug prevents accidental contact damage during blind mating—a critical requirement for field maintenance in the confined spaces of modern aircraft and complex industrial machinery.
Core Parameters:
Model Number: MS27467T25F37SD
Shell Size: 25
Contact Arrangement: 25-37 (Contains 37 high-performance size 16 contacts)
Contact Gender: Socket (S) with a “D” polarization keyway
Plating: Electroless Nickel (F) for superior conductivity and 360-degree RFI shielding
Whether deployed in Russian industrial automation or Iranian aviation projects, the MS27467T25F37SD utilizes a rapid three-pin bayonet coupling system. This mechanism provides a secure, vibration-resistant lock that remains stable even under the intense harmonic resonance found in jet engines and high-speed transport systems.
Strategic Benefits of RFI Shielding and Power Integrity
The “467” designation within this series signifies the inclusion of integrated grounding fingers. This critical design feature ensures exceptional 360-degree shell-to-shell conductivity, which is vital for maintaining signal purity in environments saturated with electromagnetic noise. By integrating the MS27467T25F37SD into your wiring harness, you effectively eliminate the risks of signal crosstalk and external interference.
Advanced Shielding and Material Reliability
Maintaining signal purity in high-frequency environments requires more than just a secure lock. The internal insulators are crafted from high-grade polymers that offer excellent dielectric strength and moisture resistance. This is paired with fluorosilicone gaskets that remain flexible under extreme pressure differentials. By ensuring a gas-tight seal, the assembly remains protected against the galvanic corrosion that often plagues equipment in maritime or high-humidity environments.
FAQ
What is the benefit of the "D" polarization in this model?
What is the benefit of the "D" polarization in this model?
The “D” keyway orientation ensures that the MS27467T25F37SD can only mate with a correspondingly keyed receptacle. This prevents accidental cross-mating in panels where multiple Size 25 connectors are co-located.
How does the Size 16 contact arrangement affect performance?
How does the Size 16 contact arrangement affect performance?
The 25-37 arrangement uses Size 16 contacts, which offer a higher current carrying capacity than the smaller 22D contacts, making the MS27467T25F37SD ideal for mixed signal and power applications.
Is this series rated for extreme temperatures?
Is this series rated for extreme temperatures?
Yes, these connectors are engineered to operate reliably in temperature ranges from -65°C up to +200°C, maintaining their mechanical and electrical properties throughout.
Can I use environmental backshells with this plug?
Can I use environmental backshells with this plug?
Absolutely. The rear of the MS27467T25F37SD is designed to accept various strain relief clamps and environmental backshells to protect the wire-to-contact junction from moisture ingress.
