2-12 PIN IP68 Waterproof Aviation Connector Plug Socket Male Female Cable Connector
The SP13 Weatherproof Aviation Connector is a compact, threaded-lock circular interface from the widely recognized SP series, featuring a 13 mm nominal shell diameter. While marketed as an "aviation plug," it serves as a versatile outdoor and industrial sealed connector for low-to-medium power and multi-signal wiring applications where M12 connectors are too small and M20/M25 connectors are oversized.
Available as cable plugs paired with panel or rear-nut sockets (straight style), these connectors support solder-cup, screw, or crimp contacts and achieve IP68 sealing when coupled—providing dust-tight protection and safe immersion beyond 1 meter.
The SP13 offers exceptional value within the SP family (SP13/SP17/SP21), sharing the same twist-lock mechanism while occupying a smaller footprint and costing less than metal aviation plugs. It maintains full interchangeability across common SP1310, SP1311, and SP1312 subtypes from major Chinese and European manufacturers (Weipu-compatible).
- IP68 Sealed Protection: Dual O-rings at the coupling face plus rear cable grommet withstand continuous immersion beyond 1 meter, pressure washing, salt spray, and condensation—surpassing RJ45 connectors, barrel jacks, and open terminal strips for outdoor equipment
- Compact 13 mm Body with 2-9 Pin Capacity: Handles 2/3-pin at 13A/250V AC, 4/5-pin at 5A/200V, 6/7-pin at 5A/125V, and 9-pin at 3A/125V—ideal for LED power, 24VDC sensor clusters, RS-485/CAN buses, and mixed power-plus-signal applications
- Threaded Twist-Lock Design: M13-class coupling nut with guide slot alignment provides vibration-resistant connections for drones, AGVs, solar trackers, and marine applications
- Flexible Termination Options: Accepts 4-6.5mm (Type I) or 5-8mm (Type II) cable outer diameter, 0.14-2mm² wire size (up to 14 AWG on 2/3-pin models)—no crimp tool required for most applications
- Premium Construction: Gold-plated brass contacts with ≤5mΩ resistance, PPS insert rated to 260°C, PA66/PC shell UL94-V0 rated, operating temperature -40°C to +85°C, 500+ mating cycles, CE/RoHS compliant
- Multiple Configuration Options: Front or rear panel nut socket, inline cable-to-cable coupler, 2-hole flange—suitable for both enclosure faceplates and harness mid-span connections
- Cost-Effective Alternative: Metal-free plastic shell eliminates galvanic corrosion, lighter than aluminum GX12/GX16 connectors, at one-third the price of metal aviation plugs

Versus M12: Larger pin capacity (13A vs 4A), up to 9 pins, wider cable outer diameter, same IP68 sealing principle
Versus Metal GX12/GX16 Aviation Plug: IP68 sealed (GX types are often non-sealed), no rust, 60-70% lower cost, lighter weight
Versus RJ45 plus Silicone Tape: Genuine keyed circular lock, survives washdown and vibration, eliminates port disconnection issues
Versus Heat-Shrink Butt Splice: Reopenable, inspectable, polarized, rated for 500 cycles
- Outdoor LED Lighting and Signage: Luminaire power and dimming connections, landscape light chains, streetlight controller faceplates
- Solar and Storage Systems: Photovoltaic combiner auxiliary feed, charge controller board supply, off-grid 12/24V bus taps
- Industrial Automation: Sensor clusters, RS-485/CAN nodes, IO-Link edge boxes, encoder extensions
