The board guide and isolated features help align the connector during panel installation and prevent ground loops through the housing. The 500-cycle rating on the 031-5493 is driven by the gold-plated centre contact — gold resists oxidation and wear through repeated mates better than tin or silver. For a panel jack that sees daily connect/disconnect in a lab or production test rack, 500 cycles translates to several years of service before the contact resistance drifts outside spec. If the connector is mated once and left in place (cable-to-equipment permanent install), the cycle count is effectively irrelevant — the dielectric and plating will outlast the equipment.","metaTitle":"Amphenol 031-5493 BNC Jack, 50 Ohm, 1 GHz, Bulkhead","metaDescription":"Amphenol 031-5493 BNC jack, female socket, 50 Ohm impedance, 1 GHz max frequency, 500 V rating, 500 mating cycles, gold-plated center contact.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors","RF Cable Assemblies"],"specifications":{"Mfr":"Amphenol RF","Series":"-","Package":"Bulk","Features":"Board Guide, Isolated","Includes":"-","Impedance":"50Ohm","Body Finish":"Nickel","Cable Group":"-","Body Material":"Zinc Die Cast","Housing Color":"Silver, White","Mating Cycles":"500","Mounting Type":"Panel Mount, Through Hole","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"0.2dB","Product Status":"Active","Voltage Rating":"500 V","Connector Style":"BNC","Frequency - Max":"1 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Front Side Nut","Ingress Protection":"-","Shield Termination":"Solder","Base Product Number":"031-54","Contact Termination":"Solder","Dielectric Material":"Polypropylene (PP)","Operating Temperature":"-55°C~85°C","Center Contact Plating":"Gold","Center Contact Material":"Phosphor Bronze"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.9300","stockQuantity":21,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is 031-5493 a BNC connector?","answer":"It is designed for 50-Ohm coaxial cable termination."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/031-5493","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/031-5493 when reusing this data.
