The TE Connectivity 1052639-1 is an SMA receptacle, female socket, built for panel-mount applications where a hermetic seal and EMI/RFI gasketing are required. It carries a 50 Ohm impedance and is rated to 18 GHz maximum frequency, making it suitable for RF signal paths up through Ku-band. The connector includes a hermetic pin and an EMI/RFI gasket in the package, so it ships as two pieces — one connector body and one hermetic pin.
The 1052639-1 is listed as Obsolete by TE Connectivity. There is no official successor order code on record. For a BOM line that calls out this exact part, the supply path is through surplus or broker channels — sourced and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time.
The stainless steel body and threaded fastening type give this connector a rugged, vibration-resistant mount. The flange secures it to the panel face, and the screw-type shield termination ties the cable braid to ground. Gold-plated beryllium copper center contact handles 500 mating cycles — a solid figure for field-serviceable RF interconnects where the connector may be swapped during maintenance. The PTFE dielectric supports the wide -65°C to 165°C operating range.
