CdS photoconductive cells are used for sensing the strength of light
The 5R type resin‑coated CdS photoconductive cell is a non‑polar resistive sensor whose resistance drops when illuminated, making it suitable for automatic light control, digital displays, cameras and teaching aids. The handbook provides typical performance data, absolute maximum ratings and dimensional information.
Key specifications such as supply voltage, ambient temperature range and light‑source characteristics are listed, together with graphs of resistance versus illuminance and temperature. Contact details for Hamamatsu worldwide offices are also included.
| Supply voltage (Vdc) | 30 V |
|---|---|
| Ambient temperature range | -30 to +50 °C |
| Standard light source color temperature | 2856 K |
Measurements are taken at a typical ambient temperature of 25 °C.
The standard tungsten lamp has a color temperature of 2856 K.
