Supplier's note

  1. Technical Breakthroughs:

    • IP67 Waterproofing: Triple-sealed design exceeds basic ingress protection standards, enabling use in heavy rain or submerged conditions up to 1m.
    • Brass Contact Conductivity: 20% lower resistance than aluminum alternatives, ensuring stable power delivery in high-temperature scenarios.
    • Modular Pin Architecture: Field-swappable pin configurations reduce downtime by 40% compared to fixed-pin systems.

  2. Version Selection Guide:

    • Base Model: Ideal for standard ebike motor extensions or low-vibration industrial sensors (e.g., temperature probes).
    • Advanced Model: Suitable for automotive ECUs or robotics arms requiring 6-pin data/power hybrid cables.
    • Pro Model: Best for extreme environments like mining equipment or aerospace systems needing 8-pin high-current reliability.

With the Pro’s 6A rating and -55°C to 125°C tolerance, you can safely power heavy-duty motors in Arctic or desert conditions. Pair its vibration-resistant housing with industrial drones to eliminate connection failures during high-G maneuvers.
