How do you handle EMC (Electromagnetic Compatibility) shielding?

For sensitive data (like Ethernet or Sonar), HYSF offers Shielded Connector Assemblies. The cable screen (braid/foil) is terminated to a specific contact pin (usually the longest ground pin) or coupled 360-degrees to the metal shell, creating a “Faraday Cage” effect to block external noise interference.

As ROVs become more electrically noisy (PWM thrusters), shielding is vital.

Standard Grounding: In standard cables, the drain wire or shield is crimped to a designated pin (e.g., Pin 1 or the center pin).
Shell Grounding: For maximum performance, we can bond the cable shield directly to the Stainless Steel/Titanium Shell. This ensures the noise is shunted to the chassis ground immediately.
Twisted Pairs: Inside the cable, signal wires are twisted to cancel out electromagnetic interference (crosstalk).

With over 15 years of expertise in subsea interconnect technology, I lead HYSF's R&D team in designing high-pressure (60MPa) solutions. My focus is on ensuring zero-leakage reliability for ROVs, AUVs, and offshore instrumentation. I personally oversee the validation of our custom connector prototypes.
