D ATA S H E E T W4-3 Miniature photoelectric sensors series The efficient space savers It is the little things that make them “big”: minimum size, maximum versatility. Three versions of the W4-3 series offer you the following benefits for your application: Clearly visible light spot. The integration of new Pin-Point LEDs creates brilliant, tightly defined light spots. Thus, the photoelectric sensors can be aligned easily and quickly, as the light spot is easy to see even in bright ambient conditions.
W4-3 Selection table Reliably solved with linear light spot featured in the WTB4-3: Continuous detection of honeycomb structured objects, n Accurate positioning, irrespective of grooves or recesses in objects, n Reliable detection of falling objects.
