Reliable detection on roller or chain link belts

The WTB4FT DoubleLine photoelectric proximity sensor detects flat objects such as smartphones up to 4 mm in thickness, even at increased sensing distances of 40 to 80 mm. Two linear light spots prevent interference from rollers or chain links. The WTV4FE V-Optics photoelectric proximity sensor is well suited for flatter objects under 4 mm in thickness. With sensing distances between 15 and 30 mm, it can even reliably detect reflective or transparent objects such as displays.
