Photoconductive Cell Typical Characteristic Curves
@ 25°C Type 3 Material
Type 3 Material
This is a high speed material with a spectral response closely approximating the human eye. This material is well suited for switching
from one light level to another and offers our best temperature stability and response time. This material is often used in cameras and
industrial controls.
The resistance for any standard catalog cell is controlled at only one light level. If the resistance at other light levels is a concern,
please contact the factory.
To obtain the typical resistance versus illumination characteristic
for a specific part number:
1. Look up 2 footcandle resistance in table.
2. Insert resistance given and draw a curve through that point
and parallel to the closest member of the family of curves
shown for the appropriate type of photo-sensitive material.
