ILB2M Power Connector — Overview

The ILB2M is a SubConn Compatible in-line (cable-to-cable / cable-to-equipment) subsea power connector, male (pins) face, from the 2-contact battery charging group of the Power series. Rated 600 V DC/AC rms at 25 A per contact (max 50 A per connector), it is wet-mateable for more than 500 mating cycles and qualified by open-face pressure testing to 800 bar / 11,600 psi — a dependable interface for marine battery packs, ROV power feeds and underwater pump units.

2 Power Contacts 600 V / 25 A Battery Charging 800 bar Open Face > 500 Wet Matings SubConn Compatible

Key Design Features

  • Marine battery charging: the 2-, 3- and 4-contact battery connectors of the Power series carry 600 V at 25 A per contact (max 50 A per connector) — purpose-built for charging subsea battery packs.
  • Keyed mating: a stainless steel location pin prevents mis-mating of multi-contact power interfaces.
  • Wet-mateable: more than 500 wet mating cycles with gold-plated brass contacts for stable, low-resistance power paths.
  • SubConn Compatible: proven connector and contact design, POM or stainless steel locking sleeves, pressure-proof dummy connectors.
  • Field installable: field-installable versions for straightforward repair and on-site assembly.
  • Rugged marine build: chloroprene rubber body, nitrile O-rings and stainless steel snap rings for offshore, defence and oceanographic service.
