The SM7275N is a failsafe mini transfer relay switch engineered for signal routing within VXIbus-based test and measurement systems. Built on Narda relay technology, this module operates across DC to 18 GHz and is actuated by a 12VDC coil, delivering reliable switching performance in compact form. SMA connectors provide RF connectivity, while its modular design enables high-density integration into the SM7000 series platform, supporting multiple switch configurations within a single VXIbus slot.
