Coaxial Switch Receptacle, 50 Ohm, 10 GHz Ceiling
The Hirose MS-162B(01) is a 50 Ohm coaxial switch receptacle from the MS-162B series, designed for surface-mount assembly. It carries a 4 mm plug diameter interface with a snap-on fastening style, and the internal switch routes the RF path when the connector is unmated — a feature that eliminates the need for a separate RF relay in switched-antenna or test-port designs. The 10 GHz maximum frequency and 0.7 dB insertion loss define the usable signal bandwidth; the 12,000-cycle mating rating is well above typical coaxial connector endurance, suited for frequent connect/disconnect cycles in portable test equipment or field-deployed radios.
12,000 Mating Cycles — Snap-On Endurance
The snap-on fastening and 12,000-cycle rating mean this receptacle is built for repeated engagement without the contact wear that limits a typical SMA or BNC to 500–1000 cycles. For a field-service technician swapping cables daily, the cycle life alone justifies the part choice over a standard coaxial jack.
