This panel-mount flange version carries a single port, threaded coupling, and a silver-plated beryllium copper center contact rated for 500 mating cycles. The 50 Ohm impedance holds through 6 GHz, covering 4G LTE, 5G sub-6 GHz, and most microwave backhaul bands. The IP67 rating — dust-tight and waterproof when mated — makes it a direct fit for outdoor antenna ports, tower-mounted amplifiers, and remote radio heads where rain and condensation are routine. ## Sealing and Environmental Range The IP67 seal is achieved through an EMI/RFI gasket at the mating face and the flange mounting — the O-ring compresses against the panel, not the thread. That means the panel cutout and gasket surface finish matter: a rough or painted flange face can bypass the seal. The PTFE dielectric holds its dielectric constant across that span, so the impedance stays stable. ## Low PIM and Contact Design The EMI/RFI gasket and low PIM feature are the reason this jack gets specified for passive intermodulation-sensitive paths — DAS combiners, tower-top amplifiers, and multi-band antenna arrays. The silver-plated beryllium copper center contact provides low and stable contact resistance across the 500-cycle life, and the white bronze body finish (a nickel-tin alloy) resists corrosion without the galvanic issues of bare brass in coastal or industrial environments. The threaded contact termination accepts the mating plug's center pin with a positive stop; the shield termination is soldered to the cable braid through the rear body.","metaTitle":"Amphenol 431-127J-52S 4.3/10 Jack, 50 Ohm, 6 GHz, IP67","metaDescription":"Amphenol 431-127J-52S 4.3/10 female jack, 50 Ohm, DC-6 GHz, 500 V, IP67 sealed, silver-plated beryllium copper contact.

The 4.3/10 interface is standardized across manufacturers, so an Amphenol jack mates with a Huber+Suhner or CommScope 4.3/10 plug of the same gender.
