ILB3F DLSB-F ILB3M DLSB-M Subsea Connectors and Cable Assemb

ILB3F DLSB-F ILB3M DLSB-M Subsea Connectors and Pre-Terminated Cable Assemblies

Shanghai Kabel Intelligence Technology Co., Ltd. supplies the ILB3F (inline female), DLSB-F (bulkhead female), ILB3M (inline male) and DLSB-M (bulkhead male) subsea wet-mateable connectors, along with fully pre-terminated underwater cable assemblies. These connectors are designed to be fully interchangeable and intermateable with SubConn® ILB/DLSB series connectors, ensuring seamless integration with existing subsea systems worldwide.

The ILB and DLSB series connectors are medium-format subsea connectors offering a robust balance of contact density, power handling capability, and compact design. They are widely used in ROV systems, subsea instrumentation, underwater camera systems, and offshore equipment where reliable, repeatedly wet-mateable connectivity is essential.

Key Features

  • SubConn® ILB/DLSB interchangeable — direct mechanical and electrical compatibility
  • Wet-mateable — can be mated and unmated underwater without power-down
  • Multiple contact configurations available (2 to 12 contacts typical)
  • Rugged anodised aluminium or stainless steel shell construction
  • Dual O-ring sealing system for reliable underwater performance
  • PEEK insulator for high dielectric strength and thermal stability
  • Gold-plated contacts for low resistance and corrosion protection
  • IP68 rated for continuous underwater operation down to 7,000m
  • Available as individual connectors or fully terminated cable assemblies

Frequently Asked Questions

Are ILB3F and DLSB-F connectors interchangeable with SubConn ILB/DLSB series?

Yes. Shanghai Kabel ILB3F, DLSB-F, ILB3M and DLSB-M connectors are designed and manufactured to be fully interchangeable and intermateable with corresponding SubConn ILB and DLSB series connectors. No modification or adapter is required.

What is the difference between ILB and DLSB connectors?

ILB (InLine Bulkhead) connectors are inline cable connectors, while DLSB (Bulkhead) connectors are panel-mount bulkhead receptacles. The F/M suffix denotes contact gender: F = female/socket contacts, M = male/pin contacts.

Can these connectors be used for both power and signal transmission?

Yes. With contacts rated at 600V and 10A each, ILB/DLSB series connectors can simultaneously carry power and signal in a single connector body, making them ideal for mixed-purpose subsea applications.

Do you supply pre-terminated cable assemblies with these connectors?

Yes. We offer fully pre-terminated cable assemblies with direct over-moulding for complete waterproof integrity. Custom cable lengths, types and configurations are available to your specification.

Installation and Handling Guidelines

Proper installation is critical for the long-term reliability of subsea connectors. Before mating, ensure all O-rings and sealing surfaces are clean and free from debris. Apply a thin layer of silicone grease to O-rings to facilitate mating and extend seal life. When mating underwater, ensure the connector faces are aligned correctly and fully engage the locking mechanism. After each dive, rinse connectors with fresh water and inspect for damage. Store with protective caps installed when not in use.

Quality Assurance

Each ILB3F, DLSB-F, ILB3M and DLSB-M connector is individually tested before shipment. Our quality assurance program includes: 100% electrical continuity and insulation resistance testing, hydrostatic pressure testing to rated depth, visual and dimensional inspection, and mating cycle verification. Certificates of conformance and test reports are supplied with each order.
