Description:
The OPB350 series liquid sensor is designed to work with 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 1/8" (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

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