SMA Jack Kit for RG-55, 142, 223, 400 — Field-Installable 50 Ohm Termination
The Amphenol RF 901-9602-1 is a field-installable SMA jack kit — a female socket, free-hanging (in-line), with threaded coupling. It ships as a 6-piece assembly: the connector body, a contact, a ferrule, a length of heat shrink, an insulator, and a nut. The kit is built for RG-55, 142, 223, and 400 cable groups, which covers the common semi-rigid and flexible coax used in test equipment, microwave links, and avionics.
What the 12.4 GHz Rating Means for the RF Path
The 12.4 GHz ceiling is the frequency at which the interface maintains its 50 Ohm characteristic impedance within specification.
Cable Prep and Termination — What Ships in the Kit
The kit includes the insulator that centres the contact in the body and the nut that secures the assembly. The cable group — RG-55, 142, 223, 400 — all share a similar dielectric diameter and braid coverage, so the same ferrule and insulator fit all four. The threaded coupling mates with any standard SMA plug (male pin) that has a 1/4-36 thread interface. The weatherproof ingress protection means the mated pair resists moisture ingress in outdoor or washdown environments, though it is not submersible.
