Circular Series 5 Pin Underwater Connector -- Inline Bulkhead Male Female | IP68 | 7000m | Power and Data

Shanghai Kabel Intelligence Technology Co., Ltd Circular Series 5-pin inline and bulkhead underwater connectors. IP68, 7000m, 20A per contact. Power plus data in one connector. SubConn Circular 5 compatible.

Product introduction

Circular Series 5-Pin Underwater Connector -- Inline and Bulkhead

The 5-contact Circular Series from Shanghai Kabel Intelligence Technology Co., Ltd is the entry point for mixed power-and-data Circular connectors -- three or four contacts carry power at 20 A each while the remaining contacts carry a serial data bus or analog signal, eliminating the need for a separate signal connector. COBH5 and COIL5 deliver IP68 protection, 7,000 m depth rating, and direct SubConn Circular 5-contact interchangeability.

Frequently Asked Questions

Can signal contacts be used at full 20 A in a 5-pin connector?

All 5 contacts are rated 20 A. However, for signal circuits carrying milliamp-level currents alongside 20 A power contacts, specify shielded cable and ensure the connector shell is grounded to minimise inductive coupling from the power contacts.


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
