Note 1) Spectral sensitivity: Sensitivity at wavelengths exceeding 400 nm as a percentage of maximum sensitivity is 100%
Note 2) This product is not designed to withstand electromagnetic radiation or heavy-charge particles.
Note 3) Difficult to guarantee compliance with moisture resistance standard (MIL-STD-202D)
*1 Measurements were made using a tungsten lamp (color temperature T = 2856K) as a light source.
