Shanghai Kabel Intelligence Technology Co., Ltd Circular Series 12, 16, and 25-contact high-density underwater connectors (COBH/COIL). IP68, 7000m depth. SubConn Circular 12/16/25 compatible.
For complex ROV, AUV, and subsea instrument systems requiring many circuits through a single pressure penetration, Shanghai Kabel Intelligence Technology Co., Ltd offers Circular Series connectors in 12, 16, and 25 contacts. These high-density configurations consolidate power distribution, digital data buses, analog sensors, and ancillary control signals into one robust wet-mateable connection point -- reducing the number of hull penetrations and the associated sealing risk.
| Contacts | Bulkhead | In-Line | Max Current | Best For |
|---|---|---|---|---|
| 12 | COBH12M/F | COIL12M/F | 10 A | Multi-sensor packages with power + 8 data |
| 16 | COBH16M/F | COIL16M/F | 8 A | Control umbilical with full signal bus |
| 25 | COBH25M/F | COIL25M/F | 5 A (derated) | Complex AUV backplane or vehicle-wide comms |

With 25 contacts sharing the shell, the thermal load per contact increases. The 5 A derating ensures the connector stays within its thermal operating envelope at full simultaneous load. For circuits requiring more than 5 A, a dedicated lower-count power connector should be used in parallel.
Yes. A common practice is to designate 4-6 contacts as power (at derated current) and the remaining contacts for signal/data. Contact our engineering team for recommended pin assignment templates for your specific application.
