Data Sheet

Model 2249
Cable Assembly with BNC
Male on Each End
FEATURES:
The molded strain relief is directly bonded to the cable jacket for superior strength and durability.
Teflon insulation and nickel tarnish resistant outer shells used in the BNC connector provide long life and
reliability.
Gold plated center contacts assure the most noise free connection possible.
The connectors and cable are impedance matched.
CABLE DESIGNATION & TYPE:
2249-C: RG58C/U, 50 ohm cable makes it ideal for most test and measurement applications, RF
transmission systems and Thinnet LAN applications.
RG59B/U, 75 ohm cable assembly for use with broadcast, video, and other signal
2249-E:
applications.
2249-K: RG174/U, smaller diameter 50 ohm cable for greater flexibility in tight applications. It is
best suited for use in low power situations where small size and flexibility is important.
2249-M: RG62A/U, 93 ohm cable, use when higher impedance, > 75 ohms is required.
2249-Y: RG223/U, double shielded 50 ohm cable assembly for superior interference rejection.
