The 3RG7642-0AB00 is a SIMATIC PXO230 M18S thru-beam sensor receiver with straight optics, M18×52 cylindrical housing, 10-30V DC supply, PNP output configured light-on, 150 mA switching capacity, and a 2-meter PUR cable with 3×0.34 mm² conductors. Rated IP67 for washdown and dust ingress protection.
The 10-30V DC supply range covers standard 24V industrial control loops with margin for brownout. PNP light-on output means the transistor switches high when the receiver sees the emitter beam — verify your PLC input card sinks or sources accordingly. 150 mA continuous output is sufficient for direct PLC inputs or small relays; for larger loads, buffer through an interposing relay. The 2m PUR cable is oil- and abrasion-resistant, suited for drag chains or flexing applications in machine tool or conveyor environments.
This receiver pairs with a matching emitter for object presence detection across gaps up to several meters in automated assembly lines, packaging machinery, and material handling systems. The M18 threaded barrel mounts in standard brackets or drilled panels.
