It runs on DC 10-36V, outputs PNP at 200 mA, and includes a programmable light/dark-on switch plus an adjustable timer from 0.01 to 1 second. The M12 4-pole connector and IP67 rating make it a straightforward swap on a machine line where the original unit has failed. The 6-meter sensing range with polarization filter handles shiny targets that would fool a standard retro. The 200 mA PNP output drives a PLC input directly. The timer (0.01-1 s) is useful for ignoring brief interruptions on a conveyor — set it and forget it. IP67 means it survives washdown without a secondary enclosure.","metaTitle":"Siemens 3RG7211-3DK42 Retro Reflective Sensor, EOL Hot","metaDescription":"Siemens 3RG7211-3DK42 SIMATIC PXO620 K80 retro reflective sensor with polarization filter.
