SMA Jack for 50 Ohm RF Paths Up to 18 GHz
The 132147-47: Extended insulation on the dielectric — PTFE — adds creepage distance between centre conductor and ground, useful in environments where condensation or contamination could otherwise track across a standard interface. The threaded coupling gives a vibration-resistant mate; the flange mount secures the connector to the panel with the jack face protruding for blind-mate or bulkhead feed-through.
What the 500 Mating Cycles and Temperature Range Mean for Field Duty
Gold-over-beryllium copper centre contact resists fretting corrosion over those cycles, maintaining consistent contact resistance through the life of the connection.
