OPB350W187Z

Tube Liquid Sensor OPB350 Series 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 “N” Package Product Photo Here “T” Package 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. Clear liquid present causes the phototransistor to sink the maximum current, while dark liquid present causes it to sink the minimum current. As bubbles pass through the tube, the signal will vary between the “liquid present” and “no liquid” states. If no liquid is present, the phototransistor sinks only a small amount of current. If no tube is present, the phototransistor sinks a larger current than in the “no liquid” state. Smaller outside diameter tubes can be used when the tube is sized up to one of the standard sizes and is fitted properly in the housing opening. For example, fluid in a 1/16” (1.6mm) outside diameter tube can be sensed when a piece of tubing with a 1/8” (3.2mm) outside diameter and a 1/16” (1.6mm) inside diameter is used as an adapter.

(5) Ee(APT) is a measurement of the average apertured radiant energy incident upon a sensing area 0.250” (6.350 mm) in diameter, which is perpendicular to and centered to the mechanical axis of the emitting surface at a distance of 0.466” (11.837 mm). Ee(APT) is not necessarily uniform within the measured area. OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
