Tape end sensor for DAT

Overview

CNB1304H is a sensor which consists of a high efficiency GaAs

infrared light emitting diode and a high sensitivity Si phototransistor

which are arranged together in the same direction. It detects the

beginning and end of a tape based on changes in the amount of light

reflected from a prism which is situated outside of the sensor.
