50 Ohm BNC Plug for RG-179/187 — Now Obsolete
It's a crimp-termination connector built for RG-179 and RG-187 coaxial cables, with a bayonet lock for quick, secure mating. The kit includes the connector body, one contact, one ferrule, and one sleeve — four pieces total, ready for field assembly. Rated for a maximum frequency of 4 GHz and a voltage rating of 500 V. The 50 Ohm impedance is standard for test equipment and telecom. Gold plating on the brass centre contact ensures reliable electrical performance over 500 mating cycles — a solid field-service life for a crimp connector.
Lifecycle: Officially Obsolete
For buyers with a BOM line that calls out 2-5221128-3, the sourcing channel is the surplus and broker market. Do not assume stock; the obsolete status means each procurement needs a fresh check.
Cable Fit: RG-179 and RG-187
This plug is designed for RG-179 and RG-187 coaxial cables. The crimp termination for centre contact and shield braid provides a reliable assembly.
The 4 GHz frequency ceiling is the hard limit for this connector's electrical performance. Beyond that, the insertion loss and VSWR will degrade. The 500 mating cycles mean it's built for repeated connect-disconnect in test or field-service roles, not a one-time permanent install. The 0.2 dB insertion loss at rated frequency is typical for a quality BNC plug.
