5 Pin GX16 Male Female Panel Mount Aviation Connector Plug βΉ150.00 Rugged IP68 Waterproofing Designed for demanding environments, this SD20 connector set provides an IP68 protection degree. This rating ensures the connection can withstand harsh conditions, including dust and moisture. The male plug features a threaded blue coupling collar that tightly secures the mating halves together, compressing the internal seals. When disconnected, the included rubber dust cap can be screwed over the female panel socket to maintain the watertight integrity of your enclosure.
High-Density 12-Pin Configuration This specific SD20 set features twelve gold-plated brass contacts, making it ideal for routing complex data alongside low-voltage power. Each of the 1.0mm diameter pins is rated to safely carry up to 5 Amps of current and supports a rated voltage of 250V (AC/DC). The rear solder cups are optimized for wire gauges up to 18AWG.
Secure Panel Mounting The female socket requires a 20mm panel-mounting hole, allowing for easy integration into custom enclosures and control boxes. The male plug features a robust rear cable gland designed to accommodate and seal around cable outer diameters ranging from 8.0mm to 12.0mm. The durable housing is constructed from flame-retardant Nylon 66 (Polyamide 66), ensuring a wide working temperature range of -25°C to 85°C.

Key Applications and Projects
CCTV and Vision Systems: Routing multiple video, control, and power feeds through a single waterproof umbilical cord for outdoor security cameras.
Automotive and Mechanical Equipment: Providing a secure, vibration-resistant connection for custom vehicle sensors or complex machinery control panels.
Communications: Linking remote outdoor radio equipment or IoT sensor hubs back to a central indoor controller.
Unlock New Capabilities (Project Evolution) The Ultimate Weather Station Hub: Simplify the wiring of your advanced outdoor meteorology rig! Instead of running a dozen separate wires through a wall for your anemometer, rain gauge, temperature, and light sensors, consolidate them. Use this 12-pin SD20 connector to carry the I2C bus, UART lines, analog signals, and 5V power through a single, professionally sealed port on your waterproof enclosure.
1 x SD20 12-Pin Male In-Line Plug
1 x SD20 12-Pin Female Panel-Mount Socket
1 x Tethered Waterproof Dust Cap


1. What does SD20 indicate? The SD20 designation indicates the connector series, specifically noting that the panel-mount socket is designed for a 20mm diameter installation hole.
2. How many pins does this connector have? This specific model features 12 contact pins.
3. What is the maximum current rating per pin? Each of the 12 pins is rated for a working current of 5A.
4. What is the maximum rated voltage? The connector is rated for 250V (AC/DC).
5. What is the withstand voltage rating? The connector has a withstand voltage rating of 1500V AC for 1 minute.
6. What wire gauge is recommended for the 12-pin version? The manufacturer recommends using AWG18 wire or smaller (less than 1.0mm in conductor diameter).
7. How do I connect the wires to the pins? The pins utilize a solder termination method; you must solder your wires into the provided cups on the rear of the contacts.
8. What is the IP rating of this connector? It features an IP68 protection degree, meaning it is dust-tight and highly water-resistant.
9. What size cable will fit through the male plug's rear gland? The rear cable gland is designed to accept an outer cable diameter ranging from 8.0mm to 12.0mm.
10. What material is the outer shell made of? The housing is constructed from flame-retardant Nylon 66 (Polyamide 66).
11. What material are the electrical contacts? The internal contacts are made of brass and are gold-plated to ensure excellent conductivity and corrosion resistance.
12. What is the diameter of the individual contact pins? The contact pins for the 12-pin model have a diameter of 1.0mm.
13. How do the plug and socket lock together? They utilize a threaded coupling mechanism; the blue collar twists to securely lock the halves together.
14. What is the expected mechanical lifespan of the connector? The connector is designed to withstand a minimum of 500 mating cycles.
15. What is the operating temperature range? The connector is rated to operate in temperatures ranging from -25°C to 85°C.
16. What is the insulation resistance of the connector? It features a high insulation resistance of 2000MΩ.
17. What is the contact resistance? The contact resistance is rated at 5mΩ.
18. Are the pins numbered for wiring? Yes, the plastic insert typically has small numbers molded next to the pins to help you match your wire mapping.
19. What is the black cap for? The tethered dust cap is used to cover and seal the panel-mount socket when the male plug is not connected, preventing water and debris from entering the enclosure.
20. What types of projects use a 12-pin connector? It is frequently used in CCTV security systems, automotive wiring, medical devices, and mechanical equipment where multiple signal lines must be consolidated.
