Position sensing - in this application the optoisolator can be used to detect the position of a moving element, often the moving element has a light or interrupts a beam of light which the phototransistor detects.The physical gap between the light emitter and detector provides a considerable degree of electrical isolation. Opto-isolators - here the phototransistor is used as the light sensor, the light emitter being relatively close, but at a different potential. Phototransistor applicationsĪs a result of their ease of use and their applications, phototransistors are used in many applications. Phototransistor circuits are normally relatively straightforward, especially of the detector is only required to detect the presence of absence of a particular light source. Phototransistors are ideal photodetectors and can be used in a host of different applications. Phototransistor basics Applications & circuits Photodarlington Optocoupler / optoisolator Phototransistor Applications & Circuit Configurations Phototransistors are used in many different applications and the circuits used tend to be common emitter or common collector.
