GX12 2-Pin Male Female Panel Mount Aviation Connector Plug

Specifications

• Connector Type: GX12 Aviation Plug, 2-pin
  
• Mounting Style: Male panel mount (hex nut base), Female cable mount (knurled threaded shell)
  
• Thread Diameter: 12mm
  
• Body Material: Nickel-plated metal
  
• Locking Mechanism: Female half's knurled shell has internal threads that screw directly onto the male half's external threads  no separate loose collar piece
  
• Panel Fastening: Hex nut on the male half, tightenable with a wrench for a secure panel seal
  
• Termination: Solder pins
  
• Rated Temperature: -60°C to +200°C [Based on GX series standard]
  

Applications

• IoT Sensor Enclosures: Weather stations, environmental monitors, and small sensor nodes where a 16mm GX16 cutout would look oversized or not physically fit
  
• RC Hobby Projects: Vehicles and aircraft scaled small enough that a GX16 connector would look disproportionate or add unnecessary bulk
  
• Wearable or Handheld Electronics: Detachable cable connections in compact enclosures where board space is at a premium

Minimum Hardware

• Soldering iron and solder both halves use solder-pin termination, so wires must be soldered directly onto each half
  
• Panel with a 12mm mounting hole smaller than the GX16's 16mm requirement, useful for space-constrained enclosures
  
• Wrench or pliers (optional)  for tightening the smaller hex nut on the panel side; note that GX12's smaller nut is easier to over-tighten and strip than the GX16's

Safety Warnings:

• Polarity Warning: Match Pin 1 to Pin 1 and Pin 2 to Pin 2 across both halves  verify pin labeling before soldering, not after
• Solder Joint Warning: The GX12's smaller pins have less spacing between them than the GX16 take extra care that solder joints don't bridge to the adjacent pin
• Mechanical Warning: Do not over-torque the smaller hex nut on the panel side — the GX12's reduced thread size strips more easily than the GX16's under excessive force

Accessories Included in the Box

• 1× GX12 2-Pin Male Panel Mount Connector
• 1× GX12 2-Pin Female Cable Mount Connector

Frequently Asked Questions

• Does this 2-pin GX12 connector fit standard 12mm panel mounting holes?
  Yes, the GX12 designation refers to its 12mm thread diameter, so it fits standard 12mm panel cutouts used across the GX connector series.
  
• Can I mate this male connector with any GX12 female connector, or only the one it's sold with?
  Any GX12 female connector with matching pin count will physically mate with this male connector, since the GX12 series maintains a consistent thread and pin layout across manufacturers.
  
• What's the difference between this GX12 connector and the GX16 connector?
  The GX12 has a smaller 12mm thread diameter compared to the GX16's 16mm, making it better suited for compact enclosures, though it also has a lower current rating due to its smaller pin size.
  
• Can I use this with a 3-pin or higher configuration device instead?
  No, this is a 2-pin only connector — for 3-pin or higher configurations, a separate GX12 connector with the matching pin count is required (Probots also stocks a 3-pin and 5-pin GX12 variant).
• What is the maximum current rating for this GX12 connector?
  Based on the GX series standard, it typically supports 2-3A due to its smaller pin size — verify against the specific batch datasheet for your exact application, especially for higher-power use cases.
  
• Is the GX12 suitable for higher-power applications like motor connections?
  For higher-current applications, the GX16 (with its larger pins and higher current rating) is generally the better choice — the GX12 is best suited for signal, sensor, or lower-power connections.
  
• Is this connector suitable for outdoor or damp environments?
  The metal body provides some environmental resistance, though full waterproofing typically requires an additional rubber cap or gasket, similar to the GX16 series.
• How do I identify Pin 1 and Pin 2 when wiring?
  Check the insulator disc on each half for printed pin numbers  if unmarked, use a multimeter to trace continuity and label them yourself before soldering.
  
• Is the pin spacing tighter on the GX12 compared to the GX16?
  Yes, due to the smaller 12mm body, pin spacing is tighter, so extra care is needed during soldering to avoid solder bridging between adjacent pins.
  
• What happens if I accidentally swap Pin 1 and Pin 2 during wiring?
  For a simple 2-pin power connection, swapping typically reverses polarity  this can damage polarity-sensitive devices, so always verify correct pin matching before powering on.
• Why won't the male and female halves screw together properly?
  This is usually caused by cross-threading during initial mating — back both halves apart fully, realign them straight, and re-thread carefully without forcing it.
  
• Why is my connection intermittent after installation?
  Check that both solder joints are fully seated and not bridging to the adjacent pin, and confirm the locking collar is fully tightened.
  
• The panel mount hex nut feels loose after installation what's wrong?
  Use a wrench to snug down the hex nut, but be cautious  the GX12's smaller nut strips more easily than the GX16's if over-torqued.
  
• Why does my connector feel like it's not locking securely?
  Confirm the female half's knurled shell is screwed down fully onto the male half's threads  a partial thread engagement causes both a wobbly connection and intermittent contact.
