GX16 2-Pin Circular Flange Male Female Panel Mount Aviation Connector Plug Set

Specifications:

• Connector Series: GX16 (16mm thread diameter)
• Pin Count: 2 Pins
• Mounting Type: Panel Mount with 3-Hole Circular Flange
• Locking Mechanism: Threaded Screw Lock
• Rated Voltage: 125V AC/DC
• Rated Current: 7A per pin
• Housing Material: Zinc Alloy (Nickel Plated)
• Insulator Material: High-temperature Bakelite
• Mounting Hole Cutout: 16mm

Minimum hardware to get started:

• Enclosure or Chassis panel : you need a physical surface with a 16mm hole to mount the flanged female socket.
• Soldering Iron and Solder : the GX16 series uses solder cup terminals, so you must solder your wires directly to the pins.
• M3 or similar mounting hardware : to secure the 3-hole flange to your enclosure panel (screws are not included with the connector).
• Multimeter : strictly required to verify continuity and ensure no solder bridges exist between the two pins before applying power.

Safety Warnings:

• Current Limits: Do not exceed 7A continuous current through this connector. Pushing higher currents can melt the bakelite insulator and cause a dead short.
• Soldering Heat: Bakelite insulators are heat-resistant but not heat-proof. Tin your wires first, and solder quickly to the connector cups to avoid warping the pin alignment.
• Polarity Standard: Aviation connectors are passive. It is entirely up to you to define which pin is positive and which is negative. Once decided, document it clearly so you do not accidentally reverse polarity when plugging in your equipment.

Frequently Asked Questions

• Is this connector compatible with standard GX16 2-pin cables?
  Yes, the male plug will mate perfectly with any standard threaded GX16 2-pin female socket.
• Can I use this connector for outdoor applications?
  This connector is robust but not completely waterproof, so it should be kept in a covered or weatherproof enclosure if used outdoors.
• Will this connector fit in a standard 16mm circular cutout?
  Yes, the threaded portion of the flange socket requires a standard 16mm circular hole in your chassis.
• Is the 3-hole flange compatible with all project enclosures?
  The flange requires a flat surface to mount flush, and you will need to drill three additional small holes for your mounting screws.
• Is this connector compatible with standard GX16 2-pin cables?
  Yes, the male plug will mate perfectly with any standard threaded GX16 2-pin female socket.
• Can I use this connector for outdoor applications?
  This connector is robust but not completely waterproof, so it should be kept in a covered or weatherproof enclosure if used outdoors.
• Will this connector fit in a standard 16mm circular cutout?
  Yes, the threaded portion of the flange socket requires a standard 16mm circular hole in your chassis.
• Is the 3-hole flange compatible with all project enclosures?
  The flange requires a flat surface to mount flush, and you will need to drill three additional small holes for your mounting screws.
• Does this connector have a standard polarity?
  No, it is a passive connector, so you must define and consistently follow your own polarity convention (e.g., Pin 1 for VCC, Pin 2 for GND).
• What size wire should I use for soldering to the pins?
  For maximum current draw (7A), we recommend using 18 AWG to 20 AWG stranded wire.
• Is the metal shell grounded to any of the pins?
  No, the pins are isolated from the zinc-alloy shell by the bakelite core, though you can manually ground the shell if EMI shielding is required.
• Do I need any software libraries to operate this connector?
  No, this is a purely passive hardware component and does not require any code or libraries to function.
• Can I run digital communication protocols like I2C through these pins?
  Yes, you can use the two pins for data lines instead of power, but you will need a separate connector for ground and VCC.
• How can I write Arduino code to detect if this connector is unplugged?
  You can use a pull-up resistor on a digital pin and wire the connector to bridge it to ground; the code will read HIGH when unplugged and LOW when connected.
