The OPTEK/TT ELECTRONICSOCB350L187Z series liquid level sensor is a highly reliable transducer designed for precise liquid detection in various applications. Manufactured in Mexico, this sensor features a robust plastic housing and is RoHS compliant, ensuring environmentally friendly operation.
Product Features:
Designed to work with outside diameters of 1/16” [1.6mm], 1/8" [3.2mm], 3/16" [4.8mm], and 1/4" [6.3mm] clear tubes
Opaque plastic housing enhances ambient light rejection for accurate sensing
Includes automatic calibration circuitry for simplified setup
Provides multiple output states: “fluid present,” “no fluid present,” and “no tube present” when reference circuitry is added
Phototransistor sinks maximum current with clear liquid; minimum current with dark liquid
Capable of detecting bubbles passing through the tube by signal variation
Mounting options include PCB mounting or remote wiring with 24” (610 mm) 26 AWG wires
Features LED indicators for calibration status and output levels (Green, Red, Blue LEDs)
Internal phototransistor load resistance can be set to approximately 2.5K, 9.6K, or 27K Ohms
Includes a Reset/Clear pin for remote calibration signaling
Complete sensing solution with interface cable and electronics included
