PRODUCT FEATURES
• Professional-Grade Signal Quality: Gold-plated brass contacts (5µm Au over 5µm Ni) with ≤7pF contact capacitance ensure clean, low-loss AV signal transfer.
• Built to Last: Zinc diecast metal shell rated for over 2,000 mating cycles, far outlasting standard plastic connectors.
• Wide Environmental Tolerance: Operates reliably from -30°C to +80°C, making it suitable for both indoor installations and demanding outdoor conditions.
• Strong Electrical Safety Margins: 1500V DC dielectric strength and >5GΩ insulation resistance provide a solid safety buffer for 50V-rated applications.
• Tool-Free Assembly: Knurled shell design allows secure hand-tightening without special tools, speeding up cable assembly production.
• Flexible Cable Compatibility: Fits a broad 4.0–6.0mm cable range with 16AWG signal and 1.5mm² power wire support, reducing SKU complexity for assemblers.

Description
The ST366 is a premium metal-shell RCA plug engineered for reliable audio/video signal transmission. Featuring a durable zinc diecast housing with a knurled grip section for secure hand-tightening, the ST366 is designed for professional AV cable assembly applications where consistent contact performance and long service life are required. The connector accepts cable diameters from 4.0–6.0mm, with a compact overall length of 58mm (49.4mm to the shoulder) and a shell diameter of Φ11mm, narrowing to Φ6–7mm at the cable entry. The ST366 is available in the standard color-coded configuration (black / red / yellow) for easy channel identification in composite AV cable sets.
Key Features
• Gold-Plated Contacts : Brass contact pins plated with 5µm gold over 5µm nickel for superior conductivity and corrosion resistance.
• Low Contact Resistance : Contact resistance greater than 10GmΩ ensures minimal signal loss.
• High Dielectric Strength : Rated for 1500V DC dielectric strength, supporting safe operation under electrical stress.
• Low Contact Capacitance : ≤7pF between contacts, minimizing signal distortion at high frequencies.
• Durable Zinc Diecast Shell : Rugged metal housing provides mechanical strength and shielding, plus a knurled section for tool-free hand tightening.
• Long Service Life : Rated for more than 2,000 mating cycles.
• Wide Cable Compatibility : Accepts cable diameters from 4.0mm to 6.0mm, with 16AWG signal wire and 1.5mm² power wire compatibility.
Material and Environmental Specifications
• Shell Material : Zinc diecast for strength and durability.
• Contact Material : Brass base with 5µm gold over 5µm nickel plating.
• Inner Core : PBTP20%GR (glass-reinforced polybutylene terephthalate) for dimensional stability and insulation.
• Flame Retardant Rating : UL94-HB rated inner core material.
• Operating Temperature Range : -30°C to +80°C, suitable for a wide range of indoor and outdoor environments.
• Electroplating Standard : Manufactured to IEC 68-2-20 electroplating standards.
• Rated Voltage : <50V, with rated current dependent on the mating connector. Packaging and Accessories • Color-Coded Sets : Supplied in standard black / red / yellow configurations for straightforward composite AV channel identification. • Bulk or Custom Packaging : Available in bulk packaging for cable assembly production lines, with custom retail packaging options available on request. • OEM/ODM Support : Customer branding, labeling, and packaging can be arranged to order — please contact Seetronic for custom packaging solutions. Assembly Instructions • Cable Preparation : Strip the cable jacket to expose the shield and center conductor, sized to match the ST366’s 4.0–6.0mm cable diameter range. • Conductor Termination : Solder or crimp the center conductor to the pin contact and the shield/ground wire to the shell, following standard RCA termination practice. • Shell Assembly : Thread the knurled outer shell over the terminated cable and hand-tighten to secure strain relief and housing closure. • Quality Check : Verify continuity and insulation resistance after assembly to confirm proper electrical connection before use. ORDERING INFORMATION Minimum order: 40 pieces of this model. Price shown is per piece. Confirm the exact model, mating connector and cable dimensions before ordering.
