The internal switch routes the signal through the receptacle until a 4mm diameter coaxial plug is snapped into place, at which point the internal contacts break the through-path and connect to the plug center pin. ## 11 GHz Bandwidth with 0.4 dB Insertion Loss The 11 GHz frequency ceiling with 0.4 dB insertion loss means this connector passes signals through the switch path with minimal attenuation across the entire sub-11 GHz band. The gold-plated phosphor bronze body and gold-plated copper alloy center contact support this RF performance while providing the 100 mating cycles typical for a snap-on coaxial interconnect. ## Internal Switch Operation and Mating Detail The internal switch feature is the defining characteristic of this connector. In its unmated state, the receptacle provides a continuous RF path through the switch contacts. When a 4mm coaxial plug with snap-on fastening is inserted, the internal contacts open and the signal is redirected through the plug. This makes the MS-156C suitable for applications like antenna diversity switching, where the receptacle acts as a normally-closed through-line that can be broken to insert a test probe or alternate signal source. The snap-on fastening provides positive retention without requiring a threaded coupling nut. ## Surface-Mount Assembly and Packaging The MS-156C is a surface-mount component with solder termination on both the shield and center contact.","metaTitle":"Hirose MS-156C Coaxial Switch Receptacle, 11 GHz, 50 Ohm","metaDescription":"Hirose MS-156C coaxial switch receptacle, 50 Ohm, 11 GHz max frequency, 0.4 dB insertion loss, SMT, gold body.
