GX16 Waterproof Connector with Pre-Wired Power Cable – 2–10 Pin for Industrial Machinery & Equipment

GX16 waterproof aviation connectors with factory-assembled pre-wired power cable leads — ready to install without soldering. The GX16 (16mm thread) is the most widely used GX series size, offering up to 10 pins at 5A per contact (2–5 pin) or 3A per contact (6–10 pin). The pre-wired format provides factory-quality solder joints with heat-shrink insulation on each conductor, eliminating field soldering. Suitable for industrial machinery sensor connections, outdoor equipment power leads, and any application requiring a compact waterproof circular connector with a ready-to-use cable assembly.

GX12 vs GX16 Pre-Wired — Size Selection

• GX12 pre-wired: 12mm thread, up to 7 pins, 5A per contact (2–5 pin). For compact equipment with limited panel space and lower pin count requirements.
• GX16 pre-wired (this product): 16mm thread, up to 10 pins, 5A per contact (2–5 pin). The most versatile GX size — larger panel cutout (16mm) but supports more pins and provides a more robust mechanical connection. Preferred for general industrial use.
• GX20 pre-wired: 20mm thread, up to 15 pins. For high pin count requirements and maximum mechanical robustness.

Frequently Asked Questions

How do I connect the pre-wired leads to my existing harness?

Use adhesive-lined heat-shrink butt splice connectors for a waterproof splice. Match the wire gauge of the pre-wired leads to the appropriate butt splice size. Insert both wire ends into the butt splice, crimp with a ratchet crimp tool, then apply heat to shrink the adhesive-lined tubing and seal the splice. For non-waterproof indoor applications, standard butt splices or solder + heat-shrink are acceptable.

What is the panel cutout size for GX16?

GX16 panel-mount sockets require a 16mm diameter panel hole. For pre-wired docking (butt joint) connectors, no panel cutout is required — both halves are on cable ends and connect mid-harness. Verify whether you need a panel-mount or docking configuration before ordering.

Can I use GX16 pre-wired connectors for 3-phase power?

Yes, for low-power 3-phase applications. A GX16 3-pin connector at 5A per contact supports 3-phase loads up to approximately 3.5kW at 400V. For higher-power 3-phase connections, use CEE industrial connectors (IEC 60309) which are specifically rated and standardized for 3-phase power distribution.

Are the wire colors standardized?

Wire color assignments vary by manufacturer. Always verify the wire-to-pin mapping with a multimeter before connecting to equipment. Common conventions: 2-pin = red + black; 3-pin = red + black + green; 4-pin = red + black + white + green. Do not assume color conventions are consistent across manufacturers or batches.

Typical Applications

• Industrial machinery: Sensor and actuator connections on production equipment
• Outdoor equipment: Power and signal connections on machinery exposed to rain
• Agricultural equipment: Sensor connections on tractors and implements
• Marine: Deck equipment and navigation instrument connections
• Repair & maintenance: Replacement cable assemblies for damaged GX16 connector leads
