Product details

Cable Fit and Termination

The 1-1478903-0: This plug is built specifically for RG-402 (.141" semi-rigid) cable. The threaded fastening type gives a secure, vibration-resistant mate with any standard SMA jack.

Mating Cycles and Body Finish

The gold body finish and gold centre contact plating resist corrosion and maintain low contact resistance over the life of the connector. The free-hanging (in-line) mounting style means it terminates a cable end and mates to a panel jack or bulkhead receptacle.
