The Siemens 3RG7214-6MC00 is a SIMATIC PXO650 K80 diffuse sensor with background suppression, designed for object detection where the background behind the target must be ignored. It operates on universal voltage 20-320 V AC/DC and provides a relay output via a C-contact (changeover) antivalent configuration through a PG11, 5-pole connector. The sensing range is 0.2 to 1 meter, and an integrated timer allows adjustable delay from 0.1 to 10 seconds. The IP67 rating holds up to the steam and washdown environments common in tire curing and other wet process areas.
What the ratings mean for fit
The universal voltage supply (20-320 V UC) means the sensor works on both AC and DC control circuits without needing a separate power supply module — handy for retrofit into existing panels where voltage may vary. The background suppression photoelectric principle nails the cure recipe for detecting dark rubber targets against a bright metal background; the 0.2-1 m range suits conveyor monitoring at press infeed. The integrated timer (0.1-10 s) eliminates an external timing relay for delayed outputs, saving DIN rail space. The PG11 gland and 5-pole connector match standard M20 knockouts; verify the cable entry size before panel prep.
