SICK Proximity Photoelectric Sensor, Rectangular Sensor, 4 → 220 mm, NPN/PNP, IP66, IP67

Overview

With the W4F, high performance and smart automation are now also available in a miniature size. The miniature sensor is the perfect complement to the product range of a new generation of opto-electronic sensors such as the W16 and W26 and, thanks tithe new ASIC technology from SICK, consistently delivers extremely reliable detection results. This allows for versatile use in a wide range of challenging installation situations.

Thanks to Foreground Suppression, Double Line, V-optics and MultiSwitch, the W4F is a high-performance application specialist: Background suppression is improved, and flat, highly-reflective and transparent objects are detected even more precisely. In addition, the W4F as Smart Sensors make monitoring and diagnostics easier than ever beforehand enable future-proof use in I4.0 plants.
