Product details

SMA Jack for RG-Type Coax — 50 Ohm, Crimp Termination

This connector is built for RG-174, RG-188, and RG-316 coax cables. The crimp-style shield termination (ferrule) and crimp centre contact give a repeatable, tool-controlled termination that doesn't rely on solder skill. The nickel-plated brass body sheds corrosion in outdoor or industrial environments, while the gold centre contact keeps the signal path oxidation-free through 500 mating cycles.

Obsolete — Sourcing Reality

No official successor part number is on record. If your design can accept a parametric alternative, a current-production SMA jack with the same 50 Ohm impedance and RG-174/188/316 cable fit may be a cleaner long-term choice.
