The gold-plated stainless steel body and threaded coupling give a corrosion-resistant, vibration-proof mate that holds through 500 mating cycles. The 1051644-1 is listed as Obsolete. There is no official replacement order code on record. If you are maintaining a legacy BOM, confirm the cable group and impedance match before committing; the kit is built for RG-174, RG-188, and RG-316 only. ## What the 500 Mating Cycles and Gold Body Mean for Field Service 500 mating cycles is a solid reconnect budget for a threaded SMA — the gold-on-stainless interface resists galling and the plating keeps contact resistance stable across repeated mate-unmate cycles in a test rack or field-replacement scenario. The gold body finish is not cosmetic; it provides a low-resistance shield path and prevents corrosion in humid or outdoor cabinet environments. This is a solder-termination plug — the centre contact solders to the cable centre conductor, the shield solders to the connector body. The PTFE dielectric handles the solder heat without melting or shifting impedance. The kit includes the heat shrink and sleeve to seal the cable entry point. Free-hanging, in-line mounting; no panel cut-out needed.","metaTitle":"TE 1051644-1 SMA Plug Kit, 50 Ohm, 12.4 GHz, Obsolete","metaDescription":"TE 1051644-1 SMA plug kit for RG-174/188/316 cable. 50 Ohm, 12.4 GHz, gold body, 500 mating cycles.
