GX16 Aviation Connector 2–10 Pin Male Female Panel Mount Nut Type – 5pcs

Description

GX16 Aviation Circular Connector – 2–10 Pin, Male & Female Panel Mount Nut Type, 5pcs

GX16 series aviation circular connectors with 16mm thread diameter — the most widely used size in the GX series for industrial equipment, scientific instruments, and audio/video applications. The panel-mount nut type allows the socket to be fixed to a panel by threading the rear nut onto the connector body from behind the panel, creating a flush, secure interface. Available in 2 through 10 pin configurations to cover a wide range of circuit requirements. The screw-lock coupling mechanism prevents accidental disconnection from vibration.

GX12 vs GX16 vs GX20 — Size Selection Guide

GX12 (12mm): Smallest. 5A per contact, up to 7 pins. For compact equipment with limited panel space. Panel cutout: 12mm.
GX16 (16mm, this product): Mid-size. 5A per contact (2–5 pin), 3A (6–10 pin). The most common GX size — balances pin count capacity with panel space. Available up to 10 pins. Panel cutout: 16mm.
GX20 (20mm): Largest standard size. Higher current capacity, more robust mechanical connection. For higher-power connections and applications requiring maximum robustness. Panel cutout: 20mm.
Selection rule: Use GX12 for compact equipment with 2–7 circuits below 5A. Use GX16 for general-purpose applications up to 10 circuits. Use GX20 for higher-current or high-cycle applications.

Frequently Asked Questions

How do I wire a GX16 connector?

GX16 contacts have solder cups on the rear of the insulator. Strip wire to 5–7mm, tin the wire end, and solder to the solder cup. Use a fine-tip soldering iron (350°C) and apply heat to the cup, not the wire — the solder should flow into the cup and wick onto the wire. Apply heat-shrink tubing over each solder joint before assembly. Crimp-type GX16 contacts are also available for higher-volume assembly without soldering.

What is the maximum current for a GX16 10-pin connector?

3A per contact for 6–10 pin configurations. The total connector current is limited by the smallest contact rating — do not exceed 3A on any single circuit. For higher-current applications, use fewer pins (2–5 pin GX16 at 5A per contact) or upgrade to GX20 connectors. For currents above 10A per circuit, use Deutsch DT or Anderson connectors rated for higher current.

Are GX16 connectors waterproof?

No. Standard GX16 connectors are rated IP50 (dust-protected, not water-resistant). For outdoor or wet environment applications, use M12 industrial connectors (IP67) or Deutsch DT series connectors (IP67). GX16 connectors are suitable for indoor equipment, protected enclosures, and applications where water exposure is not expected.

Can I use GX16 connectors for audio applications?

Yes. GX16 connectors are widely used in professional audio equipment for intercom systems, stage lighting control, and custom audio interfaces. The screw-lock coupling prevents accidental disconnection during performances. For balanced audio (XLR-equivalent), use the 3-pin GX16 with Pin 1 = GND, Pin 2 = Hot, Pin 3 = Cold. Note that GX16 is not a standard audio connector — it is not interchangeable with XLR, TRS, or other standard audio connectors.
