50 Ohm BNC Bulkhead Jack — 5-1634523-1
It is a female socket connector with a bayonet lock, rated for 500 V and a maximum frequency of 4 GHz. The kit includes the connector body, lockwasher, nut, and solder tag — everything needed for a single bulkhead installation. The centre contact is gold-plated phosphor bronze, good for 500 mating cycles, and the zinc alloy body carries a nickel finish.
No official successor order code is on record. For a BOM line that needs this exact order code, the procurement path is the surplus and broker market.
This BNC jack mounts through a bulkhead panel and is secured with the included rear-side nut and lockwasher. The shield termination is via a solder tag — a tab that accepts a ground wire or braid. The centre contact terminates with a solder cup, requiring the signal conductor to be tinned and soldered into the cup. The dielectric is polymethylpentene (PMP), a low-loss material that supports the 4 GHz bandwidth.
