This has a RayNet Female connector at one end and a RJ45 Female Gland connector at the other end. The Gland makes the RJ45 Female socket watertight.
A typical use for this cable would be to convert a ""RJ45"" Digital Radar Cable to a ""RayNet"" Radar Cable, so you can connect the cable directly into the new HS-5 Network Switch or directly into the back of an a,c,e or gS Series multifunction display.
