The 100 mating cycles is the specified reconnect life before the snap-on retention starts to soften. That is a field-service number, not a permanent-install limit: if this adapter lives inside an enclosure and gets mated once, the cycle count is irrelevant. If it is on a test cable that gets swapped daily, plan on replacing it after about three months of daily connects. The gold-on-gold contact interface (beryllium copper centre contacts, gold-plated) keeps the mating surface consistent across those 100 cycles — no tin fretting or oxide build-up.","metaTitle":"Amphenol 925-142A-51S SMPM Jack-to-Jack Adapter, 40 GHz","metaDescription":"Amphenol 925-142A-51S SMPM to SMPM jack-to-jack adapter, 50 Ohm, DC to 40 GHz, gold-plated beryllium copper body, snap-on coupling, 100 mating cycles.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Amphenol RF","Style":"Straight","Series":"-","Package":"Bulk","Features":"-","Includes":"-","Impedance":"50 Ohms","Body Finish":"Gold","Adapter Type":"Jack to Jack","Body Material":"Beryllium Copper","Center Gender":"Female to Female","Mating Cycles":"100","Mounting Type":"Free Hanging (In-Line)","Adapter Series":"SMPM to SMPM","Fastening Type":"Snap-On, Snap-On","Insertion Loss":"-","Product Status":"Active","Conversion Type":"Same Series","Frequency - Max":"40 GHz","lifecycle_stage":"unknown","Mounting Feature":"-","Ingress Protection":"-","Base Product Number":"92514","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-65°C ~ 165°C","Center Contact Plating":"Gold","Center Contact Material":"Beryllium Copper","Convert To (Adapter End)":"SMPM Jack, Female Socket","Convert From (Adapter End)":"SMPM Jack, Female Socket"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7d51cfec0e30b2802c844c9041ad36f0.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/925-142A-51S/alternatives.json"},"ai":{"faq":[{"question":"What is the fastening type on the 925-142A-51S?","answer":"Both ends use snap-on coupling — push to mate, pull to disengage.
