The SP13 aviation connector is the 13 mm shell size member of the SP waterproof circular connector family. It pairs a threaded twist-lock coupling nut with a double O-ring seal to deliver IP68 protection when mated, making it a practical sealed interface for outdoor lighting, sensor wiring, solar auxiliary circuits and mobile equipment harnesses.
Each set consists of a male cable plug and a female socket available in panel-mount (front nut or rear nut) or inline cable-to-cable styles. Contacts are solder-cup, screw-clamp or crimp type, accepting 0.14-2 mm² wire and cable outer diameters of 4-6.5 mm (Type I gland) or 5-8 mm (Type II gland).
The SP13 shares the twist-lock mating principle of the SP17 and SP21 series but occupies a smaller footprint and costs less, which makes it the preferred choice where M12 connectors are too small and M20/M25 connectors are oversized. It is mechanically interchangeable with common SP1310, SP1311 and SP1312 subtypes.

Versus M12 Circular Connector: Same IP68 concept but 13 A rating and up to 9 poles at a lower unit cost
Versus Metal GX12/GX16 Aviation Plug: True IP68 sealing, no rust, roughly 60-70% lower cost and noticeably lighter
Versus RJ45 with Silicone Tape: Keyed circular lock instead of taped joints, survives washdown and continuous vibration
Versus Heat-Shrink Splice: Reopenable and inspectable, polarised shells prevent mis-mating, rated for 500 cycles
Please specify pin count (2, 3, 4, 5, 6, 7 or 9), gender combination (male plug / female socket), mounting style (panel nut, flange or inline), termination type (solder, screw or crimp) and cable gland size (4-6.5 mm or 5-8 mm) when placing an order. Custom harness assemblies, special pin assignments and branded packaging are available on request.
