SMA plug kit for RG-55/142/223/400 — 50 Ohm, right-angle, field-terminable
The TE Connectivity 1052072-1 is a complete SMA plug kit: a male-pin, right-angle, free-hanging connector rated at 50 Ohms impedance, shipped with the end cap, ferrule, and heat shrink included. The kit is designed for cable groups RG-55, 142, 223, and 400 — the crimp shield termination handles the braid, while the center contact is soldered. The stainless steel body and threaded coupling deliver a vibration-resistant, corrosion-resistant mate rated for 500 mating cycles.
The 1052072-1 is listed as Obsolete. For a BOM line that requires this exact kit, the procurement path is a last-time-buy or surplus-channel search; a parametric substitute would need to match the 50 Ohm SMA interface, cable group compatibility, and kit contents.
What the 500-cycle rating and gold plating mean for field service
The 500 mating cycles and gold-over-beryllium copper center contact govern reconnect duty. The beryllium copper spring maintains contact normal force through those cycles.
