TT Electronics OPB350 and OCB350 Tube Liquid Sensors

TT Electronics OPB350 and OCB350 Series Tube Liquid Sensors feature opaque plastic housing that enhances ambient light rejection. The OPB350 series tube liquid sensors are designed to work with 1.6mm, 3.2mm, 4.8mm, and 6.3mm outside diameter clear tubes. OCB350 series tube liquid sensors are configured to optimize the design effort needed to use a fluid sensor with the addition of self-calibration circuitry. These tube liquid sensors can operate at a temperature ranging from -40°C to +85°C with a forward DC current of 50mA. Typical applications include non-contact fluid sensing, oils and other petroleum products, colored fluids, toner fluids, and water.

Features

Can identify if the liquid is present in clear tubes that have an outside diameter of 1.6mm, 3.2mm, 4.8mm, and 6.3mm
