SMP Blind-Mate Coaxial Receptacle — 2406848-1
The TE Connectivity 2406848-1 is an SMP-style blind-mate coaxial receptacle, designed for dense RF board-to-board or cable-to-board interconnects where the mating halves align without visual access. It is a 50 Ohm, 1-port, female socket with a snap-on fastening mechanism — the blind-mate feature lets you push modules together in a stack and get a repeatable RF connection without turning a coupling nut. Rated DC to 6 GHz, this connector covers common wireless bands, GPS, and lower microwave frequencies. The 500 mating cycles give it a solid service life for production test fixtures, field-replaceable units, or modular radio assemblies where the connector sees regular mate/unmate cycles.
Cable and Termination
This receptacle is listed for RG-316 and LMR-100A cable. The shield is crimp-terminated and the center conductor is soldered. It mates with a corresponding SMP plug (male pin) on the board or bulkhead. The snap-on retention holds the pair together against moderate vibration — no secondary lock required for most rack-and-stack applications.
Comparison with 1057230-1
The 1057230-1 is a close sibling — same 50 Ohm impedance, same snap-on fastening, same beryllium copper / gold-plated center contact. The key differences: the 1057230-1 is an OSP-style jack (not SMP), uses a stainless steel body instead of brass, and is rated to 22 GHz instead of 6 GHz. It also terminates to RG-405 semi-rigid coax with a solder shield, not a crimp. If your system needs the higher frequency band or a stainless body for a corrosive environment, the 1057230-1 is the upgrade path; for standard flexible coax up to 6 GHz, the 2406848-1 is the correct fit.
