The SP13 Weather-Resistant Aviation Connector is a compact, screw-lock circular interface from the established SP series, featuring a 13 mm nominal shell diameter. Designed as a versatile outdoor and factory sealed connector, it bridges the gap between M12 and larger M20/M25 connectors. Available as cable plug with panel or rear-nut socket configurations, it offers solder-cup, screw, or crimp contact options and achieves IP68 sealing when mated—fully dust-proof and submersible beyond 1 meter.
The SP13 represents the cost-effective champion within the SP lineup (SP13/SP17/SP21), featuring identical twist-lock mechanisms with reduced space requirements and complete interoperability among common variants from leading manufacturers.
Key Benefits
IP68 Rated Protection
Twin O-rings and rear cable bushing provide superior sealing for prolonged immersion, high-pressure cleaning, and harsh environments.
Compact Multi-Pin Design
13 mm slender body accommodates 2-9 contacts in various configurations for power and signal applications.
Threaded Twist-Lock Mechanism
M13-class locking ring ensures secure, shake-resistant connections—ideal for vibration-prone applications.
Flexible Installation
Supports soldering or screw attachment for 4-8 mm cable diameters without specialized crimping tools.
Premium Materials
Gold-coated brass contacts, PPS insulators, and PA66/PC housing ensure reliability and durability.
Versatile Configurations
Available in panel, inline, and flange variants for diverse installation requirements.
