Procurement Notes

Verify component authenticity through authorized Radiall distributors or direct manufacturer channels. Confirm that the specific suffix matches the required Ramses series specifications. Ensure environmental ratings align with operational requirements. Request official datasheets and compliance documentation prior to integration. Validate connector pinouts against system schematics to prevent interface mismatches during installation.

Selection Notes

Select this model when high-frequency switching up to 18 GHz is required. Consider the SP3T topology for single-pole multi-throw applications. Evaluate the latching feature for power efficiency in static states. Ensure the 28 Vdc control voltage is compatible with existing drive circuits. Verify D-sub connector compatibility with panel mounting constraints.
