The TE Connectivity 2406828-1 is a straight SMP plug-to-plug adapter, male-to-male, designed for blind-mate coaxial interconnects. It belongs to the Blind-Mate Coaxial series and operates at a 50 Ohm characteristic impedance, covering DC to 40 GHz — the 40 GHz ceiling places it in the upper band of SMP interfaces, suitable for high-frequency test, microwave backplane, and phased-array signal distribution.
Interface and retention
Both ends are SMP plug interfaces with male pins — the adapter does not change gender or series, so it drops into an SMP-to-SMP chain without an impedance step. The fastening type is listed as both push-pull and threaded: the push-pull action suits the blind-mate, quick-disconnect role the series is named for, while the threaded option provides a vibration-resistant lock when the application demands it. The full detent and smooth bore features noted on the adapter mean it mates with standard SMP female jacks that have either a full-detent or smooth-bore retention profile — no special interface required.
Material and environmental range
The centre contacts are beryllium copper with gold plating — the gold layer preserves low and stable contact resistance across the 100-cycle rated life, and the beryllium copper spring temper maintains normal force in the blind-mate engagement. The stainless steel body resists corrosion in lab, industrial, and outdoor-rack environments.
