Sick Inc. has launched the W9-3 photoelectric sensor in a robust plastic housing. The third-generation device offers a variety of options in sensing range, mounting and connectivity, making it suitable for detection of clear materials and of multicolored and shiny objects in the materials handling and food and beverage industries. The company credits the durability of the sensor to a proprietary molding process and a plastic called Vistal, which it says is nine times stronger than standard acrylonitrile butadiene styrene. The connector, overmolded onto the device, creates a sensor that is nearly unbreakable. A proprietary application-specific integrated circuit incorporates OES3 technology to provide good background suppression at an extended range. Due to its slotted through-hole design, the sensor has many mounting options.
