The Siemens 3RG7620-1RH00 is a proximity switch with a 30 cm sensing range, operating on a 10...30 VDC supply. This is a standard inductive or capacitive sensor for detecting metal or non-metal targets at that distance, commonly used in conveyor systems, packaging lines, and material handling where a non-contact presence check is needed.
This is a lot-sort item for liquidation buyers. The 30 cm range suits large-part detection on transfer lines. No compliance documentation is on record for this part.
