Characteristic Description
Ultra-Compact Size: With a 5.8mm diameter, it fits in tight spaces inside white goods like Haier freezers—30% smaller than standard waterproof connectors.
Dual Waterproof Ratings: Supports IP67 (dustproof, 1m water immersion) and IP68 (permanent 2m water immersion), adapting to freezer defrost cycles and accidental spills.
Gold-Plated Conductors: 2pin/6pin options with gold-plated copper conductors ensure low resistance (≤3mΩ) and resistance to frost corrosion in cold environments.
Red Fire-Resistant Ring: A red silicone waterproof ring at the connection point is UL94 V-0 flame-rated, preventing fire spread in electrical malfunctions.
Tool-Free Connection: Push-pull plug-and-play design allows quick installation during Haier’s mass production, no specialized tools required.
Market Research
The global white goods connector market is valued at $4.2B, with mini waterproof connectors growing at 8.3% CAGR. Haier, the world’s 4th-largest white goods manufacturer, reports that 75% of its new freezer models require compact waterproof connectors to fit internal wiring. Industry data shows that connectors with IP68 ratings reduce freezer repair rates by 40% (due to frost and water damage), making them a standard for premium white goods brands.
Performance Meets
Low-Temperature Durability: Operates reliably at -30°C to 70°C—perfect for freezers (typical internal temp: -25°C to 10°C during defrost).
Current Stability: 2pin models carry 2-3A, powering freezer compressors and temperature sensors without overheating.
Long-Term Seal Integrity: Maintains waterproof performance for 3,000+ defrost cycles (1 cycle = 30 mins), matching a freezer’s 10-year lifespan.

FAQ
Why is gold plating used on the conductors?
Gold resists corrosion from freezer frost and humidity, ensuring consistent conductivity over time—unlike tin-plated conductors, which can rust and cause signal loss.
Can the 6pin model be used for both power and signal transmission?
Yes. The 6pin design can allocate 2 pins for power (2A) and 4 pins for data/signals, making it suitable for smart freezers with Wi-Fi connectivity.
Is this connector compatible with Haier’s existing freezer production lines?
Absolutely. It’s designed to match Haier’s wiring standards and installation processes, with no modifications needed for assembly lines.
