Product Overview

The MS27484T12B35P is a circular plug connector in the MIL-DTL-38999 Series II family, featuring a shell size 12 and a 12-35 insert arrangement. Designed for cable-mounted connections, this configuration provides a compact interface for multiple signal connections within industrial control equipment, communication systems, and aerospace electronic assemblies.
 

Its shell construction and surface finish are designed to support electrical connectivity and environmental protection in demanding operating conditions. The three-point bayonet coupling mechanism enables quick engagement with a compatible receptacle, while the contact configuration supports secure electrical connections. The 12-35 insert arrangement is particularly relevant to applications requiring multiple signal circuits within a limited installation space.

For system integration, engineers should verify the mating connector’s shell size, insert arrangement, contact gender, and polarization position. Cable termination requirements, compatible backshell dimensions, and environmental sealing conditions should also be checked against the applicable technical drawing. AVIA Electronics supports configuration verification and technical inquiries for the MS27484T12B35P.

MS27484T12B35P (Shell Size & Configuration Options)

The MS27484T12B35P features a shell size 12 and a 12-35 insert arrangement, providing a defined mechanical interface for applications requiring multiple electrical connections within a circular connector assembly. Its configuration is intended for integration with compatible mating connectors, where accurate shell dimensions, contact layout, and polarization alignment are essential for proper installation.

  • Shell Size 12 Configuration: The specified shell size determines the connector’s mating interface and associated installation requirements. Engineers should verify connector dimensions, coupling clearance, and available cable routing space against the applicable technical drawing.

  • 12-35 Insert Arrangement: This arrangement defines the contact layout within the connector insert. Contact quantity, size, and electrical characteristics should be verified using the corresponding insert arrangement documentation to ensure compatibility with the intended wiring design.

  • Contact & Mating Compatibility: The P designation identifies the pin contact configuration. Selection of a mating connector requires verification of complementary contact gender, matching insert arrangement, and compatible keying orientation.

  • Alternative Shell Size Options: The broader connector family offers additional shell sizes and insert arrangements for different installation requirements. Alternative configurations must be selected as separate part numbers and verified for mechanical and electrical compatibility.
