SICK has released the W190 laser series of photoelectric switches.
The units have a uniform appearance, but differing sensor technology. The standard series is designed for applications with uncritical peripheral conditions while the high-grade series is designed for maximum accuracy and resolution. The CMOS scanner can solve critical detection tasks with glass, transparent plastics, or foils, with maximum detection reliability and sufficient functional reserves. Applications include the packaging industry, electronics production, and precision engineering assembly.
Teach-in programming, selectable foreground or background suppression, or adjustable timing elements remove many problems. A numerical display and control buttons simplify the setting of sensor parameters. The photoelectric switches of the high-grade series are called for if transparent objects are involved. The pixel-oriented evaluation process can deal with bulging objects such as glass bottles, flat objects like disks, thin-walled PET plastic, and clear films.
