infrared light barrier with visible beam / fork / IP67

Fork light barriers for fluid detection are suitable for fill level detection of clear, coloured or cloudy liquids through transparent container walls. They use infrared light to detect all liquids with a water content of over 15%. Thin films are ignored. This provides solutions suitable for difficult tasks such as detecting aqueous liquids in fine, transparent tubes with a small diameter (≤ 6 mm).

The fork light barriers are available with NPN or PNP switch outputs which can be switched to NC or NO as required.
