The Siemens 3RG7401-7CH52 is a SIMATIC PXO320 K20 retro reflective sensor sized for detecting transparent objects — think clear bottles or film webs on a packaging line. It runs on 10-30 VDC, switches PNP at 100 mA, and covers a 50 cm sensing range. The M8 4-pin connector keeps wiring to a single cable drop, and IP67 lets it live on the machine frame without a separate enclosure.
