GX12 Aviation Circular Connector 2–7 Pin M12 Fixed Rear Nut Panel Mount – Plug & Socket 10pcs

Description

GX12 Aviation Circular Connector – 2–7 Pin, M12 Fixed Rear Nut Panel Mount Plug & Socket

GX12 series aviation circular connectors are compact, screw-lock circular connectors widely used in industrial equipment, scientific instruments, audio/video equipment, and light electrical applications. The M12 thread (12mm diameter) provides a secure screw-lock mating mechanism that resists accidental disconnection from vibration. The fixed rear nut design allows the socket to be panel-mounted by threading the rear nut onto the connector body from behind the panel — creating a flush, secure panel-mount interface without requiring a separate mounting bracket.

GX12 vs GX16 vs GX20 — Size Selection

GX12 (12mm, this product): Smallest standard size. 5A per contact. For low-current signal and power connections in compact equipment. Panel cutout: 12mm.
GX16 (16mm): Mid-size. 5A per contact (more pins available). More robust mechanical connection. Panel cutout: 16mm. Most common size for general industrial use.
GX20 (20mm): Largest standard size. Higher current capacity. For higher-power connections and applications requiring maximum mechanical robustness. Panel cutout: 20mm.

GX12 vs M12 Industrial Connector — Important Distinction

GX12 connectors use a 12mm thread but are NOT the same as M12 industrial connectors (IEC 61076-2-101):

GX12: Chinese aviation-style connector. Screw-lock, IP50, 5A. Used in instruments, audio equipment, and light industrial applications. Low cost.
M12 industrial (IEC 61076-2-101): European industrial standard. IP67/IP68, higher current ratings, standardized pin assignments (A/B/D/X coding). Used in factory automation, sensors, and fieldbus systems. Not interchangeable with GX12.

What Questions Does This Product Answer?

"How do I panel-mount a GX12 socket?" — Drill a 12mm hole in the panel. Insert the socket body through the hole from the front. Thread the rear nut onto the connector body from behind the panel and tighten. The connector is now fixed to the panel. Connect wires to the solder cups or crimp contacts on the rear of the socket.
"Are GX12 connectors waterproof?" — No. Standard GX12 connectors are rated IP50 (dust-protected, not water-resistant). For waterproof applications, use M12 industrial connectors (IP67) or Deutsch DT series connectors.
"What is the maximum current for a GX12 7-pin connector?" — 3A per contact for 6–7 pin configurations. Total connector current must not exceed the rating of the smallest contact. Do not use GX12 for high-current applications — use DT or Anderson connectors instead.
"Can I solder wires to GX12 contacts?" — Yes. GX12 contacts have solder cups on the rear. Use a fine-tip soldering iron, 60/40 or lead-free solder, and heat-shrink tubing to insulate each solder joint. Crimp-type GX12 contacts are also available for higher-volume assembly.
