Fit and installation context
As a photoelectric proximity sensor, the WTR1-P721S09 mounts in the standard M18 or similar through-hole bracket common to SICK's photoelectric family. No special adapter plate needed for most panel or machine-frame installations. The sensing window from 300 mm to 900 mm is adjustable via the sensor's teach-in or potentiometer (depending on the variant); set it to the actual target distance during commissioning to avoid false triggers from background objects.
