Product introduction

Circular Series 6-Pin Underwater Connector -- Inline and Bulkhead

The 6-contact Circular Series from Shanghai Kabel Intelligence Technology Co., Ltd provides a balanced combination of current capacity and circuit count -- commonly deployed for systems needing 3-phase motor power plus two or three ancillary signal contacts in a single wet-mateable connector. COBH6 bulkhead and COIL6 inline connectors are IP68 sealed, 7,000 m rated, and SubConn Circular 6-contact compatible.

Typical Pin Assignments

  • C1/C2/C3 = 3-phase motor power (U/V/W at 15 A each)
  • C4 = Earth/shield
  • C5/C6 = Encoder or temperature sensor signal return

Applications

  • ROV thruster motor (3-phase) with embedded temperature sensor and earth
  • Subsea pump with motor power + fault signal + earth
  • AUV propulsion with phase power + position encoder signals
  • Offshore subsea actuator with power + position feedback + earth

Frequently Asked Questions

Is 15 A per contact sufficient for high-power ROV thrusters?

Most ROV observation-class thrusters draw 5-12 A per phase at peak load, so 15 A provides a comfortable safety margin. For work-class thrusters drawing over 15 A per phase, consider our 2-pin or 4-pin 25 A Circular Series variants for dedicated per-phase circuits.

Applications

  • ROV power and signal distribution systems requiring mixed-contact configurations
  • Subsea control systems, offshore platform equipment and underwater instrumentation
  • Marine renewable energy, oceanographic research and environmental monitoring
  • Naval defense systems, sonar arrays and underwater communication networks
  • Diving systems, underwater tools and remotely operated equipment connectivity

Customization Options

  • Customised harness cables with direct moulding to selected polyurethane cables
  • Customer-specified cable types, wire lead lengths and bulkhead thread dimensions
  • Pressure-proof dummy connectors, locking sleeves and additional accessories
  • Certified pressure testing to specific ocean depths with full documentation
