DLPIL9F 9-Pin Low Profile Subsea Ethernet Connector – In-Line Female, 300 Bar

Product Overview

The HYSF SUBSEA DLPIL9F 9-Pin Low Profile Subsea Ethernet Connector is a compact female in-line underwater connector designed for high-speed Ethernet communication in demanding subsea, offshore, marine, and underwater instrumentation applications.Belonging to the Data Low Profile connector family, the DLPIL9F features nine female electrical socket contacts and a compact in-line cable connector structure. It provides a reliable underwater Ethernet connection between subsea equipment, ROV systems, AUV platforms, underwater cameras, marine sensors, and external data communication cables.The Low Profile Data connector series is designed for applications where installation space is limited and reliable high-speed underwater data transmission is required. Its compact rectangular connector construction helps reduce the space required for cable connections and allows more connectors to be integrated into confined subsea equipment layouts.Featuring nine female socket contacts, the DLPIL9F supports 1000BASE-T Gigabit Ethernet communication through four twisted pairs and one dedicated cable screen connection. It provides data transmission rates of up to 1 Gbit/s, with a reference transmission distance of up to 75 meters using a compatible underwater Ethernet cable assembly.The DLPIL9F is particularly suitable for ROV Ethernet networks, underwater camera systems, subsea communication equipment, marine sensor networks, oceanographic instruments, and underwater data acquisition systems.The connector features gold-plated brass UNS C36000 female socket contacts, a molded Chloroprene Rubber connector body, and a flexible polyurethane cable assembly. The standard inline cable configuration uses four twisted pairs of 24 AWG (0.20 mm²) conductors with a tinned copper braid screen.Its in-line configuration allows direct cable-to-cable connection without requiring a separate panel-mounted bulkhead connector. This makes the DLPIL9F suitable for underwater cable extensions, subsea Ethernet jumpers, ROV tether connections, and equipment interconnection systems.The standard reference cable length is 100 cm (3.3 ft), with customized cable lengths and cable assembly configurations available according to project requirements.The DLPIL9F is designed to mate with compatible nine-contact male Low Profile connectors, including the corresponding DLPIL9M male in-line connector and compatible male bulkhead configurations.A compatible Low Profile locking strap provides mechanical retention for the mated connector assembly and helps prevent accidental disconnection during underwater operation.According to the official SubConn Data Low Profile 9-contact technical specifications, the connector family supports 250 V DC/AC RMS, Gigabit Ethernet transmission up to 1 Gbit/s, more than 500 wet-mating cycles, and a qualified open-face pressure test of 600 bar (8,700 psi).The same official documentation identifies a 300-bar (4,350 psi) depth rating for the PEEK bulkhead configuration. This PEEK bulkhead rating is a separate specification and should not automatically be assigned to the DLPIL9F in-line cable connector without model-specific pressure qualification.With its nine-pin female configuration, compact in-line structure, high-speed Ethernet capability, flexible PUR cable, and durable molded rubber body, the DLPIL9F provides a practical underwater data connection solution for ROV systems, AUV platforms, subsea cameras, marine monitoring equipment, and deepwater communication systems.HYSF SUBSEA provides low-profile underwater connectors, subsea Ethernet connectors, female in-line connectors, underwater data connectors, and customized subsea Ethernet cable assemblies for OEM manufacturers, ROV integrators, marine engineering companies, and offshore equipment suppliers.
