The Siemens 3RG7652-3CC00 is a SIMATIC PXO230 M18S thru-beam sensor receiver. It operates on 10-30V DC with a PNP antivalent output rated for 150 mA, sensing through a 6 m range. The M18×72 cylindrical housing carries an M12 4-pole connector and is sealed to IP67.
The 6 m sensing range is the maximum specified separation between emitter and receiver for reliable thru-beam detection. The PNP antivalent output provides both normally-open and normally-closed signals on separate pins of the M12 connector, simplifying integration with PLC inputs that expect complementary feedback. The 150 mA output current capacity is sufficient for direct drive of small relays or indicator loads without an interposing amplifier.
