PSD
One-dimensional PSD
Small, thin plastic package, long and narrow active area
S9155
S9155 is a one-dimensional PSD (Position Sensitive Detector) encapsulated in a small, thin plastic package. Even having a long and
narrow active area (5.7 mm in resistance length and 1.0 mm in width), S9155 takes up only about 1/5 of the PC board mount space
required by the conventional type.
