Description:
The OPB350 series liquid sensor is designed to work with 1/16” [1.6mm], 1/8” [3.2mm], 3/16” [4.8mm] and 1/4" [6.3mm] outside diameter clear tubes. When output reference circuitry is added, multiple output states such as “fluid present,” “no fluid present” and “no tube present” can be recognized.

Features:
• Can identify if liquid is present in clear tubes that have an outside diameter of 1/16” [1.6mm], 1/8” [3.2mm], 3/16” [4.8mm] or 1/4" [6.3mm]
• Opaque plastic housing enhances ambient light rejection
• Printed circuit board mounting or 24” (610 mm) wires 26 AWG wires

Applications:
• Non-contact fluid sensing
• IV fluid
• Oils and other petroleum products
• Colored fluids
