Photodiodes FD-7K contain photosensitive element of round shape with diameter 10 mm.
FD-7K are designed for application in photoelectric automatics.
Devices are produced in cylinder metal-glass casing with flat entrance gate, stiff lead-outs tin-plated.
Photodiodes are marked with points on device casing at cathode lead-out.
Device maximum weight 10g.
