2-Core Waterproof Connector Harness Manufacturer & Supplier

2-Core Waterproof Connector Harness Overview

The 2 core waterproof connector harness is a dedicated cable assembly engineered around dual-path current or signal transmission. Two independently insulated conductors run through a sealed connector body, allowing one compact assembly to carry both a power path and a signal path while keeping the contact zone isolated from moisture, dust and washdown spray.

Dongguan Songyuan Technology Co., Ltd. builds these harnesses in our own 2,000 m² factory in Houjie Town, Dongguan, where four dedicated areas cover harness production, wire drawing and extrusion, quality inspection, and warehousing and dispatch. Because we control both the cable extrusion and the connector termination, wall thickness, sealing integrity and crimp geometry stay consistent from the first prototype through to volume production. This assembly sits inside our broader waterproof wire harness range, which covers sealed cable assemblies for industrial, energy storage and outdoor equipment.

Buyers typically specify this product when a standard connector cannot survive the operating environment — vibration on a machine frame, condensation inside an enclosure, or routine hose-down cleaning on a production line. The dual-core format keeps the harness narrow enough to route through tight glands while still meeting the mechanical and environmental demands of the installation.

Key Features

• Convenient and durable mechanical properties. The connector engages firmly and stays seated under vibration, with a housing geometry intended for repeated mating cycles rather than single-use assembly.
• Broad environmental adaptability. The sealed interface and the material selection allow the harness to be specified across indoor cabinets, outdoor enclosures and equipment that sees regular cleaning.
• Class 6 high-flexibility annealed oxygen-free copper stranded conductor. A fine-strand, oxygen-free copper construction that supports repeated flexing and tighter bend radii in moving equipment.
• Independent core insulation. Each core wire is separately insulated with heat-resistant modified PVC or environmentally friendly TPE, so the two circuits remain electrically isolated along the full length of the run.
• "Double sealing + mechanical locking" design. Redundant sealing works together with a mechanical lock, so the seal does not rely on friction alone to stay watertight under load.
• Outer protection options. The sheath can be specified in PVC, LSZH (low smoke halogen-free) or PUR (polyurethane) to match the mechanical and fire-performance priorities of the installation.
• Certificates available upon request.

Specifications

Because the conductor, insulation and jacket are specified as a system, the finished 2 core waterproof connector harness can be tuned to the mechanical duty of the application rather than to a single off-the-shelf cable construction.

Applications

The dual-path layout makes this harness a practical choice wherever one run has to carry power alongside a control or feedback signal:

• Industrial control cabinets and machine frames, where vibration and occasional washdown are part of normal operation.
• Energy storage and new energy equipment, including outdoor enclosures exposed to humidity and temperature swings.
• Hydrogen energy and new energy systems, where sealed interconnections keep the electrical path protected.
• Outdoor and mobile equipment, such as lighting, sensors and actuator feeds routed through tight glands.
• Consumer electronics and appliance assemblies that require a sealed, repeatable connector interface.
• Industrial and server equipment, where a compact two-core sealed link simplifies internal routing.

For motion control cabinets, this harness is often specified alongside a servo driver control line so that power and control runs share the same sealing and strain-relief approach. Our manufacturing scope also covers electronic wires, energy storage wires, shielded power cables, ribbon cables and color ribbon cables, along with harnesses for industrial control, medical, energy storage, new energy and hydrogen energy applications, plus military-grade cable assemblies. Based in Dongguan, we supply wire harness solutions to customers across Southeast Asia.

Customization & Ordering

Every 2 core waterproof connector harness we quote is built to the drawing: conductor construction, core insulation material, sheath material, sealed connector type, overall length, stripping dimensions, tinning and terminal selection are all confirmed before production starts. Tell us the routing environment and the mechanical duty of the cable, and our engineers will recommend a jacket and sealing combination that fits.

Lead times and quantities

• Prototyping lead time: 48 hours for standard specifications.
• Order quantities are flexible — prototype runs from 100 pcs, volume production from 1,000 pcs.
• Mass production typically ships in 15–25 days.

Samples and pilot batches are a normal part of the process; we use them to verify connector engagement, seal integrity and crimp quality before the tooling is committed to a full run. Documentation is handled on a project basis, and certificates available upon request.

If you are working from an existing harness drawing, send it with your volumes and target date. If you are still at the design stage, share the application details and we will propose a configuration and a quotation.
