Coaxial Switch Receptacle for Automated Assembly
The Hirose MS-156NB(02) is a 50 Ohm coaxial switch receptacle in the MS-156NB series, designed as a surface-mount, single-port coaxial switch with a 4 mm plug diameter. It features an internal switch function and a pick-and-place cap, making it suited for automated PCB assembly in wireless modules, GPS receivers, and other RF front-end applications where a compact, board-level switching coaxial connection is needed.
RF Ratings and SMT Footprint
Rated at 50 Ohms impedance with a maximum frequency of 6 GHz and insertion loss of 0.1 dB, the MS-156NB(02) is sized for sub-6 GHz signal paths typical of Wi-Fi, Bluetooth, and cellular bands. The snap-on fastening type provides quick, tool-less mating and unmating, though the 100-cycle rating means this connector is best treated as a limited-reconnect component — design for test points or factory calibration rather than frequent field swapping. Surface-mount termination with solder shield termination keeps the RF ground plane continuous through the board launch.
Obsolete — Sourcing and Lifecycle
The MS-156NB(02) is officially listed as Obsolete. No direct form-fit-function successor is documented in the available records; buyers should verify compatibility with the Hirose MS-156 series for any proposed replacement.
