15 Pin GX20 Male Female Panel Mount Aviation Connector Plug 20mm

Specifications

• Connector Type: GX20 Aviation Plug, 15-pin
  Mounting Style: Male panel mount (hex nut base), Female cable mount (knurled threaded shell)
• Thread Diameter: 20mm
• Body Material: Zinc Alloy with Nickel plating
• 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 Current & Voltage: 5A per pin / 400V
• Rated Temperature: -20°C to +85°C

Minimum hardware

• 25W soldering iron with a fine tip  the smaller pins on this 15-pin variant benefit from a precise tip rather than the heavier iron needed for the 2-pin/4-pin GX20's larger contacts
• Panel with a 20mm mounting hole  same footprint as the other GX20 variants despite the highest pin count
• Wire labeling system (numbered heat shrink or colored tape)  with 15 conductors, a clear labeling system isn't optional
• Multimeter  for verifying each of the 15 individual connections during and after assembly

Safety Warnings

• Pin Confusion Warning: With 15 closely-spaced pins  the densest layout in the GX20 series  mismatching connections is more likely than on any other variant built this session
• Solder Joint Warning: Minimal pin spacing requires a fine-tip iron and minimal solder to avoid bridging adjacent pins
• Current Rating Warning: Each pin is individually rated for 5A  do not assume this connector matches the higher-current 2-pin/4-pin variants
• Mechanical Warning: Torque the hex nut properly on the panel side  identical requirement to the other GX20 variants

Accessories Included in the Box

• 1× GX20 15-Pin Male Panel Mount Connector
• 1× GX20 15-Pin Female Cable Mount Connector

Frequently Asked Questions

• Does this 15-pin GX20 connector fit standard 20mm panel mounting holes?
  Yes, the GX20 designation refers to its 20mm thread diameter, identical footprint to every other GX20 pin-count variant despite having the most pins in the series.
• Can I mate this male connector with any GX20 15-pin female connector, or only the one it's sold with?
  Any GX20 female connector with matching 15-pin count will physically mate with this male connector, since the GX20 series maintains a consistent thread and pin layout across manufacturers.
• What's the difference between this 15-pin GX20 and the 2-pin or 4-pin versions?
  The 15-pin has smaller contacts rated for lower current per pin, designed for complex multi-signal wiring rather than simple high-current power connections  it's the highest pin-count option in the GX20 lineup.
• What is the current rating per pin on this GX20 15-pin connector?
  Each pin is rated for approximately 5A, consistent with the GX20 series pattern for high pin-count variants  verify against the specific batch datasheet for critical applications.
• What is the working voltage for the GX20 15-pin?
  It's rated up to 400V working voltage, consistent with the rest of the GX20 series.
• Can I run 15 separate low-voltage signal lines through this connector safely?
  Yes, this is a common use case  signal and sensor lines typically run well within the per-pin current rating, making this ideal for combined power and multi-signal applications.
• How do I identify which pin is which when wiring all 15?
  Check the insulator disc on each half for printed pin numbers  always reference the printed numbers rather than assuming a grid position, especially at this pin density.
• Is there more risk of wiring mistakes with 15 pins compared to fewer?
  Yes, pin confusion is at its highest risk with 15 closely-spaced conductors  the densest layout in the GX20 series  so labeling wires with numbered heat shrink or colored tape before soldering is essential.
• Do all 15 pins need to be wired, or can I leave some unused?
  You can leave unused pins unconnected on both halves  just ensure they don't accidentally bridge to an adjacent active pin given the very tight pin spacing.
• Why is only some of my 15-pin connection working?
  This usually means one or more solder joints are cold or poorly seated  check each of the 15 pins individually with a multimeter rather than assuming all are fine if some are working.
• Why does one pin feel intermittent while the others work fine?
  Recheck that specific pin's solder joint for a cold joint or partial seating  at 15 pins, the densest spacing in the series, this is the most common issue.
• Could two of my pins be accidentally bridged together?
  Yes, this is more likely with 15 pins in close proximity than on any lower pin-count connector  inspect closely for solder bridging between adjacent pins if you're seeing unexpected shorts.
• Why does my connector feel like it's not locking securely?
  Confirm the female half's knurled shell is fully screwed onto the male half's threads  the locking mechanism is identical to every other GX20 variant regardless of pin count.
