This company’s Q4X laser-distance sensor (photo) has been updated to include a new dual-teach-mode model. Featuring new firmware, the Q4X dual-teach-mode sensor combines window thresholds on both target distance and target reflected intensity, and can now detect clear objects without requiring a retro-reflector. The Q4X detects distance changes as small as 1 mm, and covers a range from 25 to 300 mm. The sensor is suitable for difficult distance-based sensing applications, as it can detect objects regardless of target surface reflectivity, including black foam on black plastic, black rubber in front of metal and multicolor packaging. With the dual-teach mode, the sensor can now detect small changes in reflected intensity for targets inside the distance threshold. — Banner Engineering, Minneapolis, Minn.
