The Siemens 6GK8553-0AB00-1AA1 is an active-production SCALANCE MRB85533M radio unit built for wireless IP communication over private 5G networks in the n78 band, pushing 24 dBm transmit power. IP65 sealed, so out here in the grease it'll survive coolant drips and dust. Temperature-rated –30 to +60°C, which covers most unheated plant floors and rooftop enclosures. Power is 24 V DC via an M12 L-coded connector – the same profile you see on ruggedized field switches. The fronthaul link uses 10 Gbps SFP+ optics, so you're wiring single-mode or multimode fiber back to the SCALANCE RAN. Four N-Connect antenna ports give you MIMO flexibility. Mount it on a DIN rail or bracket; the 258 x 250 x 52.5 mm footprint fits alongside other IP65 enclosures.
Sourcing & lifecycle
Group code R323, product group X0FY – these are internal Siemens sort codes that match the SCALANCE catalog structure. They don't change the physical part, but they'll help you reconcile it against your SAP or BOM import if you've got the Siemens product hierarchy mapped.
