The MS3456 designation refers to a family of MIL-DTL-5015 Series III circular connectors manufactured by Microsemi Corporation. These components are ruggedized plugs designed for cable mounting with threaded coupling mechanisms. The series accommodates various shell sizes and contact configurations, utilizing crimp terminals for male pin or female socket arrangements. Constructed from materials such as aluminum alloy or stainless steel, these connectors provide environmental resistance against fluids and corrosion, ensuring reliable performance in demanding operational conditions.
Verify the specific suffix codes (e.g., L, W, K) to determine exact shell material, plating, and contact configuration. Confirm compliance with current RoHS directives if lead-free operation is required. Cross-reference mating part numbers to ensure interface compatibility within existing assemblies.
Select based on required shell size and contact count. Determine necessary housing material (aluminum vs. stainless steel) for weight or corrosion constraints. Verify that the chosen contact type matches the circuit requirements. Ensure the solid backshell option aligns with strain relief needs.
Microsemi Corporation produces this connector line under the MS3456 identifier, adhering to military specifications. The product falls within the broader category of circular MIL-spec connectors, serving as a critical interconnection solution for high-reliability applications where standard commercial connectors would fail due to environmental stressors.
Compatible replacements include equivalent MIL-DTL-5015 Series III plugs from other manufacturers. Verify dimensional interchangeability and contact arrangement before substitution. Ensure the alternative part meets the same environmental rating and coupling torque specifications.
