SF40M-4S4T-TS

HYSF SF40M-4S4T-TS Hybrid Photoelectric 4 Optical 4 Electrical Threaded Bulkhead Underwater Connector

Optional: Anodized Aluminum Bulkhead with Dual O-Ring Sealing

The HYSF SF40M-4S4T-TS is a high-density hybrid photoelectric threaded bulkhead watertight connector combining 4 optical fibers and 4 electrical contacts for multi-channel simultaneous data and power in space-limited deep-sea systems. Essential for large ROV umbilicals, AUV comprehensive sensor payloads, underwater high-resolution imaging with power, marine data hubs, and offshore monitoring requiring threaded hybrid connections. Engineered with marine-grade construction, precision optical components, gold-plated electrical pins, and robust threading, it maintains IP68 integrity at 6000-meter depths (60 MPa). Superior signal quality and corrosion protection establish it as the standard for 4 fiber 4 power threaded underwater connectors and deep-ocean hybrid photoelectric bulkheads from HYSF.
