Its defining feature is the integrated internal switch, which allows signal routing changes without an external relay — the switch opens or closes as the mating plug is inserted or removed. The connector style is specified as a coaxial switch with a 4mm plug diameter, meaning it mates with a 4mm-diameter plug (not a standard SMA or BNC). This is a single-port, surface-mount device with a gold-finished phosphor bronze body and a beryllium copper center contact plated in gold. 50 Ohm impedance, 6 GHz max frequency, 0.15 dB insertion loss. The dielectric material is polyamide (nylon 6T), which handles the temperature range and provides stable RF performance.","metaTitle":"Hirose MS-156HF(20) Coaxial Switch Receptacle, 50 Ohm, 6 GHz","metaDescription":"Hirose MS-156HF(20) coaxial switch receptacle, 50 Ohm, 6 GHz max, internal switch, snap-on mating, SMT, gold body.

It mates with a 4mm-diameter plug, not an SMA connector. The connector style is specified as a coaxial switch with a 4mm plug diameter, so confirm the mating plug diameter before ordering."},{"question":"Does MS-156HF(20) have an internal switch feature?","answer":"Yes, the MS-156HF(20) includes an internal switch.
