Is there an Ethernet bulkhead connector compatible with BlueRobotics ROVs?

Yes, HYSF provides a custom 8-pin Ethernet male bulkhead specifically designed with an M10 thread to perfectly fit BlueRobotics and other compact ROV enclosures. Featuring a black hard-anodized aluminum shell, this connector ensures high-speed data transmission (up to 1Gbps) and superior corrosion resistance, making it an ideal “drop-in” upgrade for underwater robotics.

Q1: What makes the HYSF M10 Ethernet connector “BlueRobotics Compatible”?

Answer: Many standard underwater connectors use larger threads (like M14 or M16), which don’t fit the compact end caps of BlueRobotics enclosures. Our custom M10 thread specification allows users to mount an 8-core Ethernet link directly into their existing setup without drilling new holes or using bulky adapters. It’s a seamless fit for seamless data.

Q2: Why is “Hard Anodized Aluminum” used for the connector shell?

Answer: While stainless steel is common, Hard Anodized Aluminum (Black) offers a unique advantage for ROVs:

  • Weight: Significant weight savings, which is crucial for maintaining neutral buoyancy in smaller ROVs.
  • Corrosion Resistance: The “Hard” anodizing process creates a thick, durable oxide layer that protects against harsh saltwater environments.
  • Aesthetics: The sleek black finish matches most commercial ROV frames and enclosures perfectly.

Q3: Can this 8-pin connector support Gigabit Ethernet speeds?

Answer: Absolutely. The HYSF 8-core (8-pin) configuration is optimized for high-bandwidth applications. When paired with high-quality shielded cabling, it supports Gigabit Ethernet (1000Base-T), ensuring low-latency 4K video streaming and high-speed telemetry for your underwater missions.

Q4: How does the “Double O-Ring” design protect my ROV?

Answer: Like our flagship series, this M10 version features a Reinforced Double O-Ring seal. Most budget connectors rely on a single seal; our dual-ring system provides a primary and a secondary barrier. This “double insurance” ensures that even if one seal is slightly compromised by debris, your ROV’s electronics remain dry and safe.
