Note 1) Spectral sensitivity : Sensitivity at wavelengths exceeding 400 nm as a percentage, is 100% to maximum sensitivity. Note 2) This product is not designed to withstand electromagnetic radiation or heavy-charge particles. Note 3) The glass strength of this product cannot withstand loads of 0.5 kg or greater. This fact needs to be taken into consideration if optical fibers are to be mounted on the product. *1 Measurements were made using a tungsten lamp (color temperature T = 2856K) as a light source. *2 Switching time measurement circuit (see figure below) Note : Detection photo current –3 dB
