Overview
The CGA 3E2C0G2A050C080AA is a high-performance circular connector meeting military-grade specifications. Designed for mission-critical applications, it features a threaded coupling mechanism and ruggedized construction capable of withstanding extreme temperatures (-55°C to +175°C) and mechanical stress. As part of the CGA connector series, this model follows standardized pin configurations while offering specialized enhancements for aerospace and defense applications. Its unique alphanumeric designation indicates specific dimensional, material, and performance characteristics important for system integrators.
Structure and Working Principle
This connector employs a multi-pin arrangement with precision-machined stainless steel shells providing electromagnetic interference (EMI) protection. The gold-plated contacts ensure low-resistance connections, while the internal glass-sealed feedthroughs maintain hermetic integrity. The bayonet-style coupling mechanism allows for quick mating while preventing accidental disconnection. Internal spring-loaded contacts maintain constant pressure even during vibration, with dielectric materials rated for high-voltage isolation between circuits.
Key Features
Military-grade durability stands as the hallmark of this connector, with certified performance under MIL-DTL-38999 Series III standards. The design incorporates triple-redundant sealing (radial, face, and rear) against moisture and contaminants. Electrical characteristics include a current rating up to 22A per contact and voltage withstand capability of 1500V RMS. The connector's compact design (approximately 50mm diameter) makes it suitable for space-constrained installations while maintaining high contact density.
Application Areas
Primary applications include avionics systems, missile guidance components, and armored vehicle electronics where reliability under combat conditions is paramount. Industrial uses extend to oilfield equipment and marine systems exposed to saltwater corrosion. In commercial aerospace, these connectors appear in flight control systems and engine monitoring units. The medical technology sector utilizes sterilizable variants for surgical robotics where electrical integrity cannot be compromised.
Maintenance and Precautions
Proper handling requires using manufacturer-specified torque wrenches during installation (typically 1.5-2.5 Nm) to prevent shell distortion. Periodic inspection should check for contact oxidation and seal degradation, especially after environmental exposure. Storage recommendations include keeping protective caps installed and maintaining controlled humidity levels. Cleaning should only use approved solvents to avoid damaging the specialized surface treatments on contacts and seals.
B2B Procurement Guide
When sourcing these connectors, verify supplier certifications for military specifications compliance. Lead times often extend 8-12 weeks due to specialized manufacturing processes and testing requirements. Consider purchasing connector kits including backshells and accessories for complete solutions. For high-volume orders (500+ units), expect 15-25% price reductions, though customization options like special plating or marking will increase costs. Always request sample testing before large purchases to confirm mating compatibility.
