SMA Plug for 1.5D-2W Cable, 50 Ohm, 1 GHz Ceiling
The Hirose HRM-200-2S-1C(40) is an SMA-style plug with a male pin, part of the HRM series. The threaded coupling gives a vibration-resistant mate, and the stainless steel body handles the usual field knocks without corroding. This plug is designed for cable group 1.5D-2W — a specific coaxial cable diameter. The PTFE dielectric keeps insertion loss predictable across the band. Gold plating on the centre contact handles the 1000 mating cycles without the corrosion that eats unplated brass.
What the 1 GHz and 1000 Cycles Mean on the Bench
The 1 GHz max frequency is the practical limit for this plug — above that, the VSWR climbs and the signal degrades. The 1000 mating cycles mean this plug survives repeated test-bench connects and field service swaps; the gold plating on the centre contact is what makes that cycle count real rather than theoretical.
