The 112288-11: It comes as a kit with 4 pieces: the connector body, a crimp contact, a ferrule, and a sleeve — so the buyer gets everything except the cable in one order code. The BNC style means quick mate/unmate with a quarter-turn, and the 500-cycle rating tells you it can handle repeated reconnections in field-service or test equipment without wearing out the gold-plated center contact.
The cable group covers RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174. If your harness uses one of those, the fit is direct; if not, the ferrule and sleeve are sized for those cable diameters, so a different cable would need a different connector variant.
