DIL8F Ethernet In-Line Connector — Overview

The DIL8F is a 8-contact SubConn Compatible Ethernet in-line subsea connector, female (sockets) face, dedicated to Gigabit Ethernet. Four twisted pairs are routed through a reconfigured gold-plated contact set that maximises data flow while eliminating cross-talk and noise, sustaining 1 Gbit/s up to 75 m.

8 Contacts 1 Gbit/s / 75 m 250 V Data 600 bar Open Face 500+ Wet Matings SubConn Compatible IP68

Key Design Features

  • True Gigabit Ethernet: 1 Gbit/s up to 75 m with CAT 5E type conductors and controlled-impedance contact geometry.
  • Wet-mateable: connect and disconnect underwater; the design eliminates cross-talk and noise in the mated face.
  • SubConn Compatible: same face geometry and thread as the SubConn Ethernet series, so it retrofits existing panels without re-machining.
  • Gold-plated contacts: female sockets in gold-plated brass UNS-C36000, male contacts in gold-plated beryllium copper for repeatable low-resistance connection.
  • CAT 5E leads: bulkheads supplied with CAT 5E patch leads (RJ45 included, not installed); inline versions moulded on 3.3 ft (100 cm) 4-pair PUR cable.
  • Depth qualified: pressure tested to 600 bar / 8,700 psi open face. PEEK body option rated 300 bar / 4,350 psi.

Mating & Compatibility

ParameterSpecification
Mates withDBH8M (bulkhead) / DIL8M (in-line)
Dummy connectorDDC8M
InterchangeabilitySubConn Compatible — SubConn Ethernet / Power Ethernet series; also interchangeable with equivalent underwater Ethernet connectors

Typical Applications

ROV and ROTV Ethernet links, HD underwater camera and video systems, sonar data streams, oceanographic instrumentation, offshore energy and defence systems, and underwater control networks.

Notes for Selection

This is a dedicated data connector rated 250 V DC/AC rms; it does not carry separate power. For combined power and Ethernet in one interface, use the 13-contact Power Ethernet variant.

Custom configurations available Bulkhead shell material (brass / 316L stainless steel / titanium / anodised aluminium / PEEK), thread and lead lengths, cable assemblies in 1, 2 and 5 m and custom harnesses can be specified to order.
