ST366
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.

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.
