The nickel-plated zinc die-cast body and gold-plated brass centre contact give this jack the corrosion resistance and mating-cycle life for portable radio gear, antenna leads, and test-point cables that get reconnected regularly. ## Which Cables It Crimps Onto The 081-183-RFX is listed for RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 — the common 50 Ohm coax types with a nominal 0.195-inch jacket diameter. If your BOM calls for LMR-195 or Belden 9907, this is the correct jack. For RG-174 or RG-316 (thinner jacket), you need the 081-183-1000 variant with a different ferrule bore. Threaded fastening — mates with any standard mini UHF plug. Free-hanging in-line mount, no panel cut-out needed. Shield and centre contact both crimp; the PTFE dielectric stays in place during the crimp cycle. ## Voltage and Temperature Envelope The 335 V ceiling is the air-gap limit at the mating interface, not the cable rating — stay below that peak for the PTFE dielectric to hold its insulation resistance. The temperature range covers outdoor telecom cabinets and unheated industrial enclosures.","metaTitle":"Amphenol RF 081-183-RFX Mini UHF Jack, 50 Ohm, 2.2 GHz","metaDescription":"Amphenol RF 081-183-RFX mini UHF jack, female socket, 50 Ohm, 2.2 GHz max, crimp termination for RG-58/LMR-195.
