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:
RG58C/U, 50 Ohm cable makes it ideal for most test and measurement applications, RF transmission
systems and Thinnet LAN applications.
2249-E:
2249-K:
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.
2249-Y:
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
