Circular Series 8-Pin Underwater Connector -- Inline and Bulkhead

Shanghai Kabel Intelligence Technology Co., Ltd 8-contact Circular Series connectors (COBH8 bulkhead and COIL8 inline) are a versatile choice for ROV and AUV subsystems that need to combine power supply with multiple data channels in one wet-mateable connection. With 8 contacts at 15 A each and a 7,000 m depth rating, these connectors handle demanding mixed power-and-signal duties.

Specifications

Typical Pin Assignment (8-contact power+data)

• Contacts 1-2: 48 V DC power supply (+ and -)
• Contacts 3-4: RS-485 data bus (A and B)
• Contacts 5-6: Ethernet pair (TX+/TX-)
• Contacts 7-8: Ethernet pair (RX+/RX-) or auxiliary analog

Applications

• ROV camera and lighting head -- power + video signal + PTZ control
• Subsea sonar with power + multi-channel digital output
• AUV science payload with power + RS-232 + analog sensors
• Subsea DVL (Doppler Velocity Log) interface connector
