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.
The rated insulation voltage is 690 V, as per IEC 60947-5-1. This is the maximum voltage for insulation design. Always verify the specific model's rating with the manufacturer.
The mechanical endurance is 1,000,000 operations without load, according to IEC 60947-5-1. This indicates the expected lifespan under mechanical actuation. Actual life may vary with operating conditions.
The degree of protection ranges from IP20 to IP65, depending on the enclosure and mounting. IP20 is for basic protection, while IP65 offers dust-tight and water-jet protection. Confirm the final rating with the enclosure used.
The contact material is silver alloy AgNi10, which provides low contact resistance and good resistance to welding. This is a common material for switching contacts in control circuits.
