The Siemens 3RG7212-6EK00 is a SIMATIC PXO630 K80 thru-beam sensor receiver in a compact 83x61x25 mm housing. It operates on UC 20-230V supply and provides a 50 m sensing range with NPN output, programmable light-on or dark-on, plus an adjustable timer from 0.1 to 10 seconds. The PG11 cable gland and 5-pole connection suit panel-mount installations where IP67 ingress protection is required.
This part carries an EOL Hot lifecycle stage, meaning Siemens has formally ended production.
The 50 m range is the maximum specified distance between emitter and receiver under clean conditions; actual usable range depends on dust, fog, and alignment. The NPN output sinks up to 200 mA, which drives most PLC inputs directly. The timer range of 0.1–10 s allows pulse stretching or delay-on-drop for conveyor or fill-level applications. IP67 means the housing withstands hose-down and temporary submersion, but the PG11 gland must be properly torqued to maintain the seal.
