Introduction
MS3112E18-32SN MIL-DTL-26482 Circular Connector Receptacle, 32-Pin Socket, Solder Terminal, Panel Mount, Aluminum Alloy, for Military-Aerospace/Industrial Use
Product Overview
The MS3112E18-32SN is a high-reliability circular connector from KAIDA, fully compliant with MIL-DTL-26482 Series I military specifications. Designed for high-density signal and power transmission in harsh environments, this box-mount receptacle features 32 female socket contacts (size #20) with rugged aluminum alloy housing, gold-plated conductive components, and a secure bayonet coupling system.
This configuration ensures stable connectivity under extreme conditions including intense vibration, wide temperature fluctuations, and chemical corrosion, making it ideal for military, industrial, and aerospace applications requiring high-density, failure-resistant connections.

Key Features
High-Density Connectivity
32 integrated contacts enable simultaneous transmission of multiple signals and medium-power currents, reducing connector count in complex systems by 40%+.
Military-Grade Durability
Compliant with MIL-DTL-26482 Series I for resistance to extreme environmental stressors, critical for mission-critical equipment.
Quick & Secure Coupling
Bayonet lock design allows fast mating (1/4-turn) without tools, with self-levelling mechanism to prevent contact damage.
Low Signal Degradation
Gold-plated contacts maintain low resistance (<4mΩ) even after 500 mating cycles, minimizing signal attenuation.
Anti-Misinsertion Polarization
Five keyway positions ensure precise alignment with mating plugs, eliminating incorrect connections.
Broad Compatibility
Standard MIL-DTL-26482 pinout enables seamless replacement of legacy connectors in existing systems.
