It is a flange-mount, surface-mount design with compression termination on the centre contact and screw termination on the shield — built for permanent board attachment where the RF path needs a clean launch up to 27 GHz. The 27 GHz frequency ceiling and 500 V voltage rating place this connector in the upper band of standard SMA performance — it handles the full X-band and most of the Ku-band without rolling off. The 500-cycle mating life, gold-plated beryllium copper centre contact, and PTFE dielectric are what you expect from a production-grade RF interconnect that sees field service, not just a one-time bench test. The stainless steel body and silver housing finish give it corrosion resistance for lab, outdoor cabinet, or instrument environments. The included mounting hardware — two screws plus the connector — means the flange can be bolted directly to a panel or chassis without sourcing extra fasteners. ## Mounting and Termination — What the Installation Looks Like The centre contact uses compression termination — the signal pin is pressed onto a pad or trace, not soldered into a plated hole. The shield is terminated via a screw, which means the ground connection is made through the flange and the screw-down hardware, not through solder joints. That makes it well-suited for assemblies where the board is bolted to a metal chassis and the ground reference is established through the enclosure. The threaded fastening type is standard SMA — mates with any male SMA plug that has the same 1/4-36 thread. The flange mounting feature gives mechanical retention independent of the solder joints, so the connector stays put even if the board flexes or the cable is torqued during mating.","metaTitle":"Molex 73251 0732511851 SMA Receptacle, 50 Ohm, 27 GHz","metaDescription":"Molex 0732511851 SMA receptacle, female socket, 50 Ohm, 27 GHz max, 500 V, 500 mating cycles.
