It's a right-angle, free-hanging (in-line) connector with a snap-on fastening, crimp shield termination, and a solder contact. The 6 GHz frequency ceiling means it's good for applications like Wi-Fi (2.4/5 GHz), cellular bands, GPS, and general-purpose RF test leads. Push past 6 GHz and the VSWR climbs; stay within the band and the snap-on interface holds a repeatable connection. This plug is built for RG-178B coax — a thin 30 AWG solid or stranded center conductor cable with a 1.8 mm OD. The shield is crimped, the center conductor is soldered. The right-angle body keeps the cable routed close to the board or panel face, which matters in tight enclosures where a straight plug would bend the coax too sharply.","metaTitle":"Hirose MMCX-LP-178B/U(40) MMCX Plug, RG-178B, 50 Ohm, 6 GHz","metaDescription":"Hirose MMCX-LP-178B/U(40) MMCX plug, male pin, right-angle, free-hanging. 50 Ohm, 6 GHz max, 500 mating cycles.
