Coaxial Switch Receptacle for RF Signal Routing
The Hirose MS-162A is a surface-mount coaxial switch receptacle with a 4 mm plug diameter, designed for RF signal routing in compact modules. The internal switch feature allows it to redirect the signal path — typically used for antenna diversity, transmit/receive switching, or test-port isolation in wireless infrastructure and instrumentation. The gold-plated brass body and beryllium copper centre contact, both gold plated, give this receptacle corrosion resistance and consistent ground-path shielding over 12000 mating cycles — a cycle count that points to test-equipment or frequent-mate duty rather than a permanent install.
This is a single-port female socket receptacle with a 4 mm plug diameter. It mates with a snap-on coaxial plug of the same diameter. The surface-mount package is supplied in Tape & Reel for automated pick-and-place assembly.
