Combining window thresholds on both target distance and target reflected intensity, Q4X Laser Distance Sensor can detect clear objects without requiring retro-reflector. Dual mode can be used to error-proof applications by ensuring correct color part is located at correct position. Constructed with FDA-grade stainless steel housing rated to IP67, IP68, or IP69K for high-pressure washdown environments, sensor covers 25–300 mm range and can detect distance changes as small as 1 mm.
