The Siemens 3RG7175-0CD00 is a SIMATIC PXO230 L18 laser thru-beam sensor receiver in a rectangular M18×75 housing. It operates on DC 10-30 V, delivers a PNP light-on output at 200 mA, and achieves a 50 m sensing range. The 2 m PUR cable with 4×0.25 mm² conductors and IP67 rating suit it for wet or dusty environments where surplus light detection is needed.
Fit & Installation
Mounts in a standard M18 threaded hole; the rectangular optics housing needs about 75 mm of clearance behind the panel. The 2 m PUR cable is oil- and abrasion-resistant, suitable for drag-chain or flexing applications. Power and signal share the same cable — verify the wiring scheme against the nameplate before terminating, as the light-on logic expects a dark condition to switch the PNP output off.
