75 Ohm BNC Plug — Kit Includes Connector, Bushing, Contact, Ferrule
The 31-71008: It ships as a complete assembly kit: 1 connector body, 1 bushing, 1 center contact, and 1 ferrule — everything needed to terminate one cable end without sourcing separate parts. This is a 75 ohm variant, not the more common 50 ohm BNC. The impedance mismatch between a 50 ohm cable and a 75 ohm connector causes a reflection at the junction — so this plug is intended for 75 ohm systems (video, broadcast, CCTV, some data networks) where the characteristic impedance of the cable and the connector must match.
NRND Status — What It Means for Sourcing
This means the manufacturer no longer actively promotes it for new projects, though it may still be available through distribution channels for existing production or maintenance.
The 31-71008 is specified for cable groups RG-59, RG-59B, RG-62, RG-140, RG-210, and Belden 8241, 8263, 8279, 9209. These are all 75 ohm cables with a nominal impedance match to the connector. The center contact accepts either crimp or solder termination; the shield termination is crimp-only via the included ferrule.
RF Performance and Mechanical Ratings
Rated to 2 GHz maximum frequency with 0.2 dB insertion loss, this plug suits baseband video and lower-frequency RF links where 75 ohm impedance is required.
