SP13 3 Pin Aviation Plug Socket Connector 13A 250V IP68 Waterproof Male Female with Dustproof Cap for Outdoor Industrial Power Wiring
Product Overview
The SP13 3 pin aviation plug socket connector is a compact screw-locking circular interface with a 13 mm nominal shell diameter, purpose-built for outdoor and industrial power runs that need a sealed, repeatable connection. The 3-contact layout carries the highest rating in the SP13 family — 13 A at 250 V AC — making it the preferred choice for single-phase AC power, LED drivers, solar combiners and mobile equipment feeds.
Each set consists of a cable-end male plug and a panel-mount female socket with rear nut, supplied with a dustproof cap that keeps the interface sealed while unmated. Contacts are solder-cup terminals, assembled in the field with standard soldering tools and no special crimp die.
Mated pairs reach IP68 protection through a dual O-ring seal plus a rear cable bushing gland, so the connection stays dust-tight and submersible beyond 1 meter, and survives washdown, salt fog and vibration on mobile machinery.
Key Advantages
- 3-contact layout delivers 13 A at 250 V AC — the highest power rating available in the SP13 housing size
- IP68 sealing when mated, verified by dual O-rings and a compression cable gland for 4-6.5 mm and 5-8 mm cable jackets
- Threaded twist-lock coupling stays seated under vibration and can be operated with work gloves on
- Gold-plated phosphor bronze contacts hold contact resistance at or below 2 mΩ for stable low-loss power transfer
- Dustproof cap protects both halves during transport, storage and maintenance windows
- PA66 / PC shell rated UL94-V0 with PPS insulator, working from -40 °C to +85 °C
- Lightweight corrosion-free plastic body, lower cost and safer than metal shell aviation connectors
- Rated for 500 or more mating cycles, so field servicing does not consume the connector
