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.","metaTitle":"SICK WTR1-P721S09 Photoelectric Proximity Sensor, 300-900 mm","metaDescription":"SICK WTR1-P721S09 photoelectric proximity sensor with 300-900 mm sensing range.
