Sick W4-3 Series Proximity Sensor Switch Miniature Photoelectric Sensors
   
  Applications
  The W4-3 family of photoelectric sensors offers best-in-class performance in a miniature housing design. Using the latest ASIC and PinPoint LED technologies, these sensors provide reliable object detection of transparent and glossy objects like blisters, e-cards and aluminum cans. Optical axes on the flat side enable simple, space-saving integration in machine environments - even without mounting brackets.
