Overview

Reliable object detection for demanding applications

SICK's W18-3 photoelectric sensor series reliably detects objects under difficult application conditions. Different variants are available, including proximity sensors with high-precision background suppression, retro-reflective sensors with autocollimation and through-beam sensors with high operating reserves. These sensors are immune to ambient light, background reflections and light absorbing objects, making them a reliable sensor solution. The W18-3 series can also be customized according to the customer’s requirements in critical applications. And, these sensors are available with IO-Link, which is the new sensor communication standard of the future.
