A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory data, the rated voltage range is 24–480 V AC/DC. However, this is a reference range; the actual rated voltage for a specific model must be confirmed with the manufacturer or supplier.
A solid-state switch uses semiconductor components to switch circuits without moving parts, offering faster switching speeds, longer lifespan, and higher reliability compared to electromechanical relays, which rely on mechanical contacts.
The directory lists IEC 60947-4-1 for rated voltage and current, IEC 60068-2-1/2 for temperature, IEC 60947-1 for dielectric strength and insulation resistance, and IEC 60529 for IP rating. These are procurement references; compliance must be verified with the manufacturer.
The control voltage is typically 3–32 V DC, and the control current is 5–20 mA at rated control voltage. These values are reference ranges and should be confirmed for the specific model.
