HYSF MCIL12F is the highest-density 12-pin female inline cable connector with Ø15.7 mm PU overmold. IP68 rated, 60 MPa tested, ideal for maximum-channel Gigabit Ethernet + multi-power tethers, ultra-high-density micro-ROV umbilicals, AUV sensor chains, and deepsea inline splicing up to 6000m.

The HYSF MCIL12F achieves an industry-first 12 channels in the ultra-compact Ø15.7 mm Micro envelope — the highest pin density ever in any wet-mate inline connector under 20 mm. Its 28 mm hex grip and tapered nose ensure fast, reliable mating even in the most confined spaces.
Precision-machined 316L stainless steel insert with gold-plated brass sockets, fully encapsulated in black polyurethane with integrated strain relief. Pre-terminated with 12 color-coded PTFE leads. Supports 1000BASE-T Ethernet (two shielded twisted pairs) while leaving 8 pins for power or additional sensors.
Perfect for next-generation observation-class ROVs, deepsea instrumentation, and Ethernet + multi-power payloads where minimum diameter and maximum channel count are critical. ISO9001-2015 certified with 100 MPa burst validation and 1000+ mating cycles under pressure.
