OPB350 Datasheet Tube Liquid Sensor

Manufacturer: TT Electronics

General Description

: The OPB350 series liquid sensor is designed to work with 1/16” [1.6 mm] 1/8” [3.2 mm], 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.

Clear liquid present causes the phototransistor to sink the maximum current, while dark liquid present causes it to sink the minimum current.

Overview
