RP-SMA Bulkhead Jack for 1.37 mm Coax
The 901-10802: It mounts in a panel cutout via the bulkhead front-side nut and seals to IP67 when mated — dust-tight and waterproof, which is uncommon for an SMA-class connector. The 50 Ohm impedance holds to 7.1 GHz, with a PTFE dielectric keeping the signal path stable across the band.
Cable Prep and Termination
Shield termination is crimp; the centre contact is solder. The cable group is 1.37 mm coaxial cable — the crimp ferrule and dielectric support are sized for that OD. On the harness floor, that means a specific crimp die set for the shield braid and a soldering station for the centre pin. The 500 mating cycles are adequate for field-service reconnect duty; the gold-on-gold contact interface keeps insertion loss stable over those cycles.
What the IP67 Rating Means on an RF Connector
IP67 is rare on an SMA-threaded connector. It means the mated pair — jack plus plug — keeps out dust and survives immersion in 1 m of water for 30 minutes. The seal is at the bulkhead face, not the thread; the O-ring compresses against the panel when the front-side nut is torqued down. This connector is suited for outdoor antenna feeds, weather-exposed radio enclosures, or washdown-area equipment where a standard SMA would corrode or leak.
