FPT101 Description
Hermetic Coaxial Silicon Phototransistor Optoelectronic Products 4-39 FPT101 General De.crlptlon The FPT101 is a miniature phototransistor in a hermetic, welded case. A large photosensitive base bined with a flat window affords exceptional sensitivity without the need for critical alignment. In tape and card reader applications, the flat window permits flush mounting in the wear-plate thereby minimizing cross-talk.
