What This BNC-to-BNC Adapter Is
The TE Connectivity 5-1634534-1 is a straight BNC jack to BNC jack adapter from the Greenpar series, converting between two BNC interfaces of the same series. The adapter is free-hanging (in-line), meaning it couples two BNC cables or bulkhead jacks without requiring a panel cutout or PCB footprint — useful for extending a coax run or adapting between cable assemblies in a harness. Both ends are female BNC sockets (jack, female socket), so this adapter joins two male BNC plugs end-to-end. The body is nickel-plated zinc alloy, with a dielectric of polymethylpentene (PMP) supporting the RF signal path.
Sourcing and Lifecycle — Obsolete, Sourced to Order
TE Connectivity lists the 5-1634534-1 as Obsolete. No official successor part number is recorded in the lifecycle data. If your design can accept a parametric alternative, a current-production BNC-to-BNC adapter from the same Greenpar or another TE series may be evaluated, but no direct cross-reference is on record.
This adapter mates any two male BNC plugs — standard bayonet-lock interface on both ends. The fastening type is bayonet lock on both sides, so the connection is quick-twist and vibration-resistant within the BNC coupling's typical limits. Use it to join two cable assemblies with male ends, or to convert a bulkhead BNC jack to a through-line. The free-hanging body means no panel hardware is needed; the adapter sits in-line supported by the cable strain relief of the mated connectors.
