The extended insulation feature adds creepage distance for the 335 V rating, useful in higher-voltage RF paths or environments where humidity or altitude reduce air breakdown thresholds.
What crosses when the original is dry?
The 1052986-1 is marked Obsolete per the TE lifecycle status. For a BOM that needs this footprint and electrical performance, the closest path is a parametric match from the same SMA receptacle class — same panel-mount right-angle form factor, 50 Ohm, 18 GHz rating, with gold centre contact and PTFE dielectric. A cross-reference search against the base product number 1052986 may yield a currently active variant or a manufacturer-recommended substitute; without an official successor, the spot-market broker channel is the primary source for date-coded original stock.
What the 500-cycle rating means for field service
500 mating cycles is the standard endurance for an SMA-class connector with gold-over-beryllium-copper centre contacts. For a permanent outdoor installation that is mated once, the cycle count is effectively infinite — the limiting factor becomes environmental corrosion, not mechanical wear.
Panel mount with a flange, secured by the threaded fastening type. The shield is terminated to the panel ground via solder, and the centre contact terminates with a solder cup for the coaxial centre conductor. The stainless steel body and silver housing colour are standard for SMA connectors that see outdoor or industrial environments.
