Model 2249
Cable Assembly with BNC (M) on Each End
Features
•
•
•
•
The molded strain relief is directly bonded to the cable
jacket for superior strength and durability.
PTFE 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:
2249-E:
2249-K:
2249-Y:
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 applications.
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.
RG223/U, double-shielded 50 Ohm cable assembly for superior interference rejection.
Materials
BNC male: Body – Brass, Tarnish Resistant Nickel Plating
Center Contact – Brass, Gold Plated
Dielectric – PTFE
Strain Relief:
PVC molded directly to cable and connectors
