TT Electronics OPB350 and OCB350 Liquid Sensors

TT Electronics OPB350 and OCB350 Liquid Sensors use optical detection to identify liquid conditions in clear tubes ranging from 1/16" to 1/4" outside diameter. The OPB350 versions require external circuitry for fluid state identification, while OCB350 versions integrate an OCB100AZ calibration circuit with automatic calibration, a preset trip level, and analog and logic outputs. These sensors offer an LED forward DC current of 50mA. Applications include water, coloured fluids, oils and petroleum products, IV fluids, and toner fluids.
