DLPIL13M 13-Pin Low Profile Subsea Hybrid Connector — Power and Ethernet, In-Line Male, 300 Bar

DLPIL13M — 13-Pin Low Profile Hybrid Subsea Connector Overview

The DLPIL13M is a 13-pin In-Line Male subsea connector purpose-built for demanding underwater systems operating at depths to 3,000 m (300 Bar). It transmits 1000Base-T Gigabit Ethernet and 300V AC/DC power power through a fully sealed, vulcanized neoprene overmold body that is pressure-tested before every shipment. Designed as a drop-in-compatible component for professional ROV, AUV, cabled observatory, and deep-sea instrumentation programs worldwide.

Unlike commercial-grade connectors that degrade rapidly in saline environments, every DLPIL13M is manufactured with gold-plated copper alloy contacts, a chemically bonded neoprene overmold, and multi-point sealing geometry that eliminates micro-gap flooding — the primary failure mode in lesser designs.

Key Design Features

• Low-profile 13-pin hybrid body — highest pin count in the LP series; delivers multiple power circuits plus Gigabit Ethernet in a compact cable-mount form factor
• 13-pin layout — supports complex multi-circuit power distribution and full Gigabit Ethernet simultaneously
• 300 Bar (4,350 psi) depth rating — 100% pre-shipment hydrostatic testing on every unit
• Vulcanized neoprene overmold — molecular bond, no adhesive gaps, continuous deep-sea immersion rated
• Gold-plated contacts — maintains low-resistance power delivery and clean ethernet signaling across all 13 contacts simultaneously
• Full LP13 family interoperability — mates with DLPBH13x and DLPIL13x variants for flexible architecture
• 50% connector reduction vs. separate power + data connectors at each multi-circuit instrument interface
• No minimum order quantity, 1–2 week standard lead time

Electrical & Mechanical Specifications

Typical Applications

• ROV umbilical multi-circuit power-data cable extension joints
• Advanced AUV tether complex payload power and telemetry connections
• High-channel subsea mooring instrument hybrid cable terminations
• Multi-circuit deep-sea instrument cable-to-cable interfaces without housing penetration
• Compact hybrid cable extensions for next-generation deep-sea systems
• Dense cable harness hybrid connection points in space-constrained ROV tooling

Why the DLPIL13M Outperforms Generic Subsea Connectors

1. Direct-Bond Vulcanized Neoprene Overmold

The neoprene is vulcanized directly onto the connector body under heat and pressure, creating a molecular bond with zero adhesive interfaces. Adhesive-based seals — common in lower-cost connectors — creep, delaminate, and admit water within months of sustained deep-sea pressure cycling. The DLPIL13M's overmold maintains integrity across thousands of pressure cycles without maintenance.

2. 100% Pre-Shipment Hydrostatic Pressure Testing

Every unit is individually hydrostatically tested to rated depth before shipment — not batch sampled, not statistically inferred. This eliminates latent seal defects that would otherwise only reveal themselves after expensive subsea deployment.

3. Gold-Plated Contacts for Corrosion-Free Signal Integrity

Gold plating on copper alloy contacts provides a thermodynamically stable interface that resists chloride-induced corrosion even after years of continuous saltwater exposure. Contact resistance remains below 5 mΩ per pin throughout the connector's service life, preserving full Gigabit Ethernet link performance.

4. Industry-Standard Mating Interface

The DLPIL13M mates with all other connectors in the 13-Pin Low Profile Hybrid family, enabling system designers to mix bulkhead and in-line terminations without custom adapters. This interoperability reduces spare parts inventory and simplifies field servicing.

5. No Minimum Order Quantity

Available from single-unit quantities with standard 1–2 week lead time. Suitable for prototype programs, research vessel outfitting, and production deployments alike.
