  • Detect position of edge of material
  • Reflector mode version also available
  • Compact, metal housing
  • Reproducibility of 0.03 mm
  • Sensing distance 25 mm or 100 mm
  • Measurement range up to 30 mm
  • Analog output 4 mA ... 20 mA
  • Your benefits

  • Cost-effective solution to reliably determine edge position
  • Easy-to-integrate, compact housing can be mounted over the web so less downtime is required for maintenance
  • No reflector is required, reducing maintenance and providing greater product reliability. Reduces downtime. Only array sensors available in diffuse mode, making them ideal for environments where dirt and dust can interfere with other types of solutions that require a reflector.
  • High reproducibility of 0.03 mm and industry-leading resolution enable greater accuracy and quality control
  • Highly visible white LED light spot ensures fast and accurate alignment, reducing time-consuming fine adjustment
  • No teach, program or menu activities make setup virtually hassle free
