The 4 GHz ceiling covers the VHF through lower microwave bands; above that the connector geometry starts to introduce mode conversion and the VSWR climbs. The silver-plated beryllium copper centre contact gives good conductivity and spring memory — 1000 mating cycles is high for a BNC, meaning this jack was designed for test-rack or field-swap duty where the connector sees regular connect-disconnect cycles without the centre pin losing its grip. ## Obsolete — Sourcing Reality The BNC-LR(40) is listed as Obsolete. No official successor part number is on record. If the design can accept a parametric alternative, a current-production 50 Ohm BNC jack with similar flange-mount and right-angle PCB tails would be the practical next step, but no pin-compatible drop-in is documented under this series.","metaTitle":"BNC-LR(40) BNC Jack, 50 Ohm, 4 GHz, Obsolete","metaDescription":"BNC-LR(40) BNC jack, 50 Ohm, 4 GHz, silver-plated BeCu centre contact, 1000 mating cycles.
