OPB350 - Tube Liquid Sensor

General Description

The OPB350 series liquid sensor is designed to work with 1/16” [1.6mm] 1/8” [3.2mm], 3/16” [4.8 mm] and 1/4” [6.3 mm] 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.

Key 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" [4.8 mm] or 1/4" [6.3 mm].
  • Opaque plastic housing enhances ambient light rejection.
  • Printed circuit board mounting or 24” (610 mm) 26 AWG wires “N” Package “C” Package “T” Package.
