The TE Connectivity Greenpar 1-1478987-0 is an SMA jack, female socket, panel-mount bulkhead connector for RG-402 (.141" semi-rigid) cable. The threaded coupling and front-side nut mounting give it a positive mechanical lock through the panel, and the gold-plated stainless steel body with gold-over-beryllium copper center contact handles 500 mating cycles without signal degradation. The kit includes the connector, contact, gasket, insulator, lockwasher and nut — six pieces total, bulk packaged.
No official successor order code is available.
The RG-402 cable group means this connector accepts.141" diameter semi-rigid coax with a solid outer conductor — the shield terminates via solder, and the center contact also solders. The PTFE dielectric in the connector matches the cable's dielectric to maintain the 50 Ohm impedance through the transition. The threaded SMA interface mates with any standard SMA plug; the gold plating on both the body and center contact keeps contact resistance low and corrosion at bay in repeated mate/unmate cycles.
The 500-cycle mating life is typical for a gold-plated SMA — the gold-on-gold interface wears slowly, and the beryllium copper center contact retains its spring force over that range. For a test-jig or field-service connector that gets reconnected daily, that cycle count is the practical limit before the contact resistance drifts. The bulkhead front-side nut mounting means the connector body stays fixed while the cable assembly rotates during tightening — a detail that matters when the semi-rigid coax has a pre-formed bend that must clock correctly to the panel.
