IP68 Waterproof Male Female Wire Connector 9 Pin 6 Pin Aviation Plug Connector

The SP13 Waterproof Aviation Connector is a compact, threaded-coupling circular interconnect in the well-known SP (Shell Push-lock / Pintail) family, built around a 13 mm nominal shell diameter. Despite the name "aviation plug", it is widely used as a general-purpose outdoor/industrial sealed connector for low-to-mid power and multi-signal wiring where an M12 is too small and an M20/M25 is overkill.

It ships as a cable plug + panel/rear-nut socket pair (straight style), with solder-cup, screw, or crimp contacts, and delivers IP68 sealing when mated—dust-tight and immersion-safe beyond 1 m. The SP13 is the value leader of the SP series (SP13 / SP17 / SP21): same twist-lock logic, smaller footprint, lower cost than metal aviation plugs, and fully intermateable across common SP1310 / SP1311 / SP1312 sub-types from major Chinese/EU makers (Weipu-compatible).

• vs M12: Bigger pins (13 A vs 4 A), up to 9 pins, larger cable OD, same IP68 logic
• vs metal GX12/GX16 aviation plug: IP68 sealed (GX is often non-sealed), no rust, 60-70% cheaper, lighter
• vs RJ45 + silicone tape: True keyed circular lock, survives washdown and vibration, no port flapping
• vs heat-shrink butt splice: Re-openable, inspectable, polarized, 500-cycle rated

• Outdoor LED & signage: luminaire power+dimming, landscape light chains, streetlight controller faceplate
• Solar & storage: PV combiner aux, charge controller board feed, off-grid 12/24 V bus taps
• Industrial automation: sensor clusters, RS-485/CAN nodes, IO-Link edge boxes, encoder extensions
• Robotics / drones / AGV: tool-side power+signal, UAV gimbal harness, mobile robot skin ports
• Marine & RV: bilge pump feeds, deck lighting, helm control cables (fresh-water / splash rated)
• Stage, event, medical carts: temporary outdoor audio, portable monitor power, cart battery disconnect
