It carries a gold-plated stainless steel body and a beryllium copper centre contact with gold plating — the materials you expect for a connector that sees repeated matings in test or field-service gear. The PTFE dielectric keeps losses low across the band. This is a panel-mount, right-angle part with a flange for secure chassis attachment. The threaded fastening and solder shield termination lock the ground reference before the centre pin makes contact — standard practice for maintaining the 50 Ohm impedance through the transition. Rated for 500 mating cycles, it holds up in production test or calibration setups where the cable gets swapped regularly.
The extended insulation feature (noted on the part) adds creepage distance between the centre conductor and the shell — useful in applications where the 335 V rating is approached, or where condensation might be a concern inside an unsealed enclosure.
