It belongs to the MS-151NB series and uses a 4.15 mm plug diameter interface with a snap-on fastening type. The connector is a single-port, female socket configuration rated for 50 Ohm impedance and a maximum frequency of 3 GHz. Insertion loss is held to 0.6 dB, making it suitable for applications where signal integrity through the switch path matters. ## Surface-Mount Right-Angle — Board-Edge RF Layout The MS-151NB-1 uses surface-mount, right-angle termination, which places the RF port parallel to the PCB plane. ## Internal Switch Feature — Integrated Signal Routing This connector includes an internal switch, meaning the receptacle itself contains a switching mechanism that routes the RF signal between the center contact and an internal termination or alternate path when unmated. This eliminates the need for an external RF switch in applications where the connector's mated/unmated state must control signal flow — for example, in antenna path selection or test-point isolation.","metaTitle":"Hirose MS-151NB-1 Coaxial Switch, 50 Ohm, 3 GHz, 5000 Cycles","metaDescription":"Hirose MS-151NB-1 coaxial switch receptacle, 50 Ohm, 3 GHz max, 5000 mating cycles.
