The Siemens 3RQ4052-2SM30 is an output optocoupler from the SIRIUS 3RQ4 coupling relay family in the narrow 6.2 mm housing. It switches one normally-open contact at 24 V DC coil voltage, rated for 6 A thermal current — enough for pilot-duty control signals, small contactors, or PLC output isolation in a crowded DIN-rail panel. The housing is 6.2 mm wide.
RoHS compliance is effective from 26 September 2024.
The group code is R711 and the product group is 4950. These are Siemens internal classification codes used for catalog sorting and cross-referencing within the SIRIUS system.
Spring-loaded push-in terminals accept solid or ferruled stranded wire. The housing is 6.2 mm wide, fitting the SIRIUS 3RQ4 narrow design format.
