A reflector must be used in combination with these sensors. They can be installed in all kinds of industrial environments thanks to ample functional reserve. Even reflective objects can be reliably recognized through the use of polarized light.

  • Glossy objects can be detected
  • Micro-design
  • Contamination warning
  • Integrated output
