TCST5123 Vishay Telefunken Transmissive Optical Sensor with Phototransistor Output Description These devices have a compact construction where the emitting-light sources and the detectors are located face-to-face on the same optical axis. The operating wavelength is 950 nm. The detector consists of a phototransistor. Due to the special construction, the depth of the gap is equal to a package height of 4 mm. Applications D Position sensor for shaft encoder, D Detection of opaque material such a
