Overview
The Sick WTB4-3P2262S41 is a compact photoelectric proximity sensor from Sick’s W4 series, engineered for reliable object detection in industrial automation applications. This sensor uses ASIC and PinPoint LED technologies to provide reliable object detection of transparent and glossy objects like blisters, e-cards and aluminum cans. With optical axes on the flat side, it enables simple, space-saving integration in machine environments—even without mounting brackets.
