Right-Angle SMB Jack for Board-Edge RF Routing
The 142146-11: The gold-plated brass body and gold center contact plating give it corrosion resistance for repeated field mating, and the snap-on fastening locks with a positive click rather than requiring a coupling nut.
500 mating cycles is a solid number for a snap-on RF connector. A threaded SMA might give you 500 too, but the snap-on here saves time on repeated connects — think test-point access or modular RF modules swapped during maintenance. The gold-on-gold contact interface (center contact and body finish both gold) keeps the mating wear from degrading contact resistance across those cycles.
Temperature Range and Dielectric
This makes the 142146-11 a candidate for outdoor radio heads or engine-compartment RF links where the ambient sees both deep cold and waste heat.
