Photologic?Slotted Optical Switch
OPB917 Series
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Notes:
(1)   Normal application would be with light source blocked, simulated by I
F
= 0 mA.
(2)   All parameters tested using pulse technique.
