The Siemens 3RG7202-6HC42 is a SIMATIC PXO630 K80 thru-beam sensor receiver, part of a paired photoelectric system. It operates on DC 10...36 V, delivers a 50 m sensing range, and provides an NPN antivalent output rated at 200 mA. The housing measures 83x61x25 mm with a PG11 cable gland and 4-pole connection, sealed to IP67.
The 50 m thru-beam range suits long-distance presence detection across conveyor lines, gantries, or warehouse aisles. The NPN antivalent output gives both normally-open and normally-closed signals on separate wires — useful for fail-safe logic or dual-channel monitoring. The 200 mA sink current handles most PLC inputs and small relays directly. IP67 means the housing tolerates washdown and dust, so it fits food, beverage, or heavy-industrial environments without an extra enclosure.
