The metal body provides better mechanical robustness and EMI shielding compared to plastic-body variants. The panel-mount nut type allows the socket to be fixed to a 12mm panel hole by threading the rear nut from behind the panel. Available in 2 through 7 pin configurations for a wide range of circuit requirements.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e GX12 (12mm thread diameter)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin Configurations:\u003c\/strong\u003e 2, 3, 4, 5, 6, 7 pin (select above)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Rating:\u003c\/strong\u003e 5A per contact (2–5 pin); 3A per contact (6–7 pin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 250V AC\/DC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Copper alloy, gold-plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Zinc alloy (metal), nickel-plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating:\u003c\/strong\u003e IP50 (not waterproof)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePanel Cutout:\u003c\/strong\u003e 12mm diameter hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 5 pieces (sets)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eMetal Body vs Plastic Body GX12\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMetal body (this product):\u003c\/strong\u003e Zinc alloy construction.

Insert the socket body through the hole from the front. Thread the rear nut onto the connector body from behind the panel and tighten finger-tight, then 1\/4 turn with a wrench. Do not overtighten — excessive torque cracks the insulator on plastic-body variants and strips the thread on metal-body variants. The connector is now fixed to the panel. Connect wires to the solder cups on the rear of the socket.\u003c\/p\u003e\n\n\u003ch4\u003eWhat is the pin numbering convention for GX12 connectors?\u003c\/h4\u003e\n\u003cp\u003eGX12 pin numbers are marked on the insulator face of the connector. Looking at the mating face (the face that connects to the plug): pins are numbered clockwise starting from the largest pin (or the pin at the top, depending on the specific variant). Always verify pin numbering against the connector’s insulator markings — do not rely on memory or assumed conventions, as different manufacturers use different starting positions.\u003c\/p\u003e\n\n\u003ch4\u003eCan I use GX12 connectors for 24V DC industrial applications?\u003c\/h4\u003e\n\u003cp\u003eYes. The 250V AC\/DC rating covers 24V DC industrial control voltages. The 5A per contact rating (2–5 pin) supports most 24V sensor and actuator current requirements. For 24V applications drawing more than 5A per circuit, use GX16 (5A per contact, more robust) or Deutsch DT connectors (13A per contact, IP67).\u003c\/p\u003e\n\n\u003ch4\u003eAre GX12 and GX16 connectors interchangeable?\u003c\/h4\u003e\n\u003cp\u003eNo. GX12 (12mm thread) and GX16 (16mm thread) are different sizes and are not interchangeable. The housings, contacts, and panel cutout sizes are all different. GX12 and GX16 connectors will not mate with each other. Always verify the thread size before ordering replacement connectors.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eScientific instruments:\u003c\/strong\u003e Sensor connections, probe interfaces, measurement equipment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial equipment:\u003c\/strong\u003e Control panel connections, machine interface wiring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAudio equipment:\u003c\/strong\u003e Intercom systems, stage lighting control, custom audio interfaces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDIY electronics:\u003c\/strong\u003e Custom enclosure connections, modular power supplies, test equipment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRobotics:\u003c\/strong\u003e Compact sensor and actuator connections on small robots\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e5 pieces — GX12 aviation connector sets (male plug + female socket, pin count as selected).
