Visible red LEDs also tend to punch through moderate dust and steam better than infrared in wet environments, though the exact excess gain curve depends on the target surface and distance.","metaTitle":"Omron E3RB-DN21 Photoelectric Sensor, Visible LED Light","metaDescription":"Omron E3RB-DN21 photoelectric sensor with visible LED light source.
