MS27467T23B55PN: High-Density Interconnects for Modern Avionics
In the sophisticated landscape of aerospace engineering and defense electronics, managing complex signal pathways requires components that offer both density and extreme reliability. The MS27467T23B55PN is a premier 55-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 intense physical stress and high-frequency electromagnetic interference.
The MS27467T23B55PN configuration is optimized for Shell Size 23, housing 55 independent signal circuits. Its robust aluminum construction, paired with an Olive Drab Cadmium finish, makes it a preferred choice for central processing units, radar arrays, and tactical communication hubs.

Technical Features of the MS27467T23B55PN Configuration
The design philosophy of the MS27467T23B55PN focuses on safety, reliability, 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 heavy industrial machinery.
Core Parameters:
Model Number: MS27467T23B55PN
Shell Size: 23
Contact Arrangement: 23-55 (Contains 55 high-performance size 20 contacts)
Contact Gender: Pin (P) with a “N” (Normal) polarization keyway
Plating: Olive Drab Cadmium (B) for superior corrosion resistance and EMI shielding
Whether deployed in Russian industrial automation or Iranian aviation projects, the MS27467T23B55PN utilizes a rapid three-pin bayonet coupling system. This mechanism provides a secure, vibration-resistant lock that remains stable under the intense harmonic resonance found in jet engines and high-speed transport systems.
Strategic Benefits of RFI Shielding and Grounding
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 MS27467T23B55PN into a wiring harness, engineers can 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 Size 20 contacts in this model?
What is the benefit of the Size 20 contacts in this model?
Size 20 contacts strike a perfect balance between circuit density and power handling, allowing the MS27467T23B55PN to manage extensive data multiplexing within a compact footprint while maintaining low contact resistance.
How does the "scoop-proof" design protect the pins?
How does the "scoop-proof" design protect the pins?
The shell of the MS27467T23B55PN is elongated so that the mating contacts cannot be touched or bent by the leading edge of the mating receptacle, even during an angled blind mate.
Is this series rated for maritime and salt-spray exposure?
Is this series rated for maritime and salt-spray exposure?
Yes, the Olive Drab Cadmium plating provides exceptional protection against galvanic corrosion, making the MS27467T23B55PN suitable for up to 500 hours of continuous salt spray exposure.
Can I use environmental backshells with this plug?
Can I use environmental backshells with this plug?
Absolutely. The rear of the shell is designed to accept various strain relief clamps and environmental backshells to protect the wire-to-contact junction from moisture ingress and physical strain.
