SMA plug for RG-402 semi-rigid coax — 50 Ohm, 18 GHz
The threaded coupling gives a vibration-resistant mate; the crimp shield termination and push-on centre contact are standard field-termination methods for semi-rigid coax.
This plug is built for RG-402 (.141" diameter semi-rigid) cable — the cable group is specified in the part definition, so the centre conductor and dielectric dimensions match the push-on contact and the crimp ferrule fits the shield braid or outer conductor. The shield termination is crimp; the centre contact is push-on, meaning no solder pot to fill. On a harness bench, you cut the cable to length, strip the dielectric, push the centre contact onto the centre conductor, and crimp the ferrule over the braid. The threaded coupling nut secures the mate.
Obsolete — sourcing path
No official successor order code is recorded in the lifecycle data. If the design can be revised, a parametric search on 50 Ohm SMA plugs with RG-402 compatibility and 18 GHz rating will identify current-production alternatives, but no direct pin-compatible replacement is named in the official record.
