OES3 - the Third Generation Chip for Background Suppression
The OES3 sensors utilize a multi-segmented receiver array that allows for better background suppression performance. Also, the unique Active Area Management feature allows for the elimination of false readings from reflective surfaces or influences of other sensors in the same environment. Twenty-plus years of custom ASIC design allows SICK to provide the best processing algorithms to eliminate the external influences of high-frequency lighting, EMC, ESD, and other industrial "noise."

W.4-3 Photoelectric Sensor
The W.4-3 series provides high performance in a miniature housing. This is an ideal sensor for packaging, electronics, and small-part assembly machines.

W.18-3 Photoelectric Sensor
The W18-3 series possibly gives the best mix of price/performance/size in the industry. With more than 50,000 pieces of this latest-generation sensor already installed, this new line of sensors has proven its abilities in demanding applications.

W.27-3 Photoelectric Sensor
The W.27-3 series is the workhorse for long-range, demanding applications, proven in automotive, wood processing, and other high-stress areas. The W.27-3 series also includes several models available for AC-power applications with extended voltage range of 24 – 240 VAC/DC.
