The SP13 connector features a small 13mm outer shell diameter, gold-plated brass contacts, insulation resistance of 2000MΩ, and toughness to last any kind of environment.

Some examples of where it can be found are LED lighting, outdoor CCTV, medical devices, underwater equipment, solar energy inverters, military batteries, communications equipment, and testing devices.

One of its best features is its ability to take on cable diameters ranging from 4 to 6.5mm (type I) or 5 to 8mm (type II). This is achieved through its adjustable grommets. These can be tightened to accommodate the small cable sizes, keeping them waterproof. The openings are protected by double silicone ring seals that prevent water or particulate entry when mated or covered by the dust cap.

All these great features and more are available on the SP13 connector for your use. Brought to you by INTE-AUTO, the leader in the quality connector and custom cable assembly technology in China.
