Ax20 array sensors for edge and diameter detection solutions

Your Benefits

  • Cost-effective solution to reliably determine edge position and width measurement
  • 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


Ax20 array sensors for edge and diameter detection solutions

Array sensors use closely spaced beams of light to detect even the slightest differences in gray scale between the target and the background within their field-of-view. They are ideal for edge and diameter detection as well as detecting widths and gaps. SICK’s array sensors offer industry-leading reproducibility, in addition to compact, rugged metal housings for use in highly restricted or harsh environments.
