The hard gold-plated contacts are specified for low-level switching — gold flash prevents oxidation on circuits that never break rated current, so it fits PLC output isolation, signal-level routing, or dry-contact sensing where standard silver-alloy contacts would film over.
RoHS compliance effective 26 September 2024, and REACH candidate-list information is available on request. No UL or CSA listing is stated in the record, so verify with the factory if your panel requires a third-party mark.
Integration note
Snap-on DIN-rail mount, 24 V DC coil — pull the supply from a standard PELV power supply. The single change-over contact is rated for signal-level loads; the hard gold-plating means it should not be used at the full rated current of a standard power relay without checking the manufacturer's derating curve. Use for isolating 24 V DC digital signals between a PLC output and a field device.
