Reflex Sensor with Background Suppression
OHI122C0103
  • External Teach-In
  • Hygienic Design makes it easy to clean
  • Made with food safe materials that are FDA approved
  • waterproof IP68 and IP69K
Together with other components, wenglor’s InoxSens Sensors create an innovative system which can be seamlessly integrated into your machine. Their innovative design allows contamination and cleaning agents to flow off by themselves. The configuration is made through external Teach-In. The laser welded stainless steel housing made of V4A (1.4404/316L) is corrosion-free and resistant to cleaning agents. The captive optics are made of either glass or plastic. The InoxLock system is used for gap-free mounting.
