Fujikura reserves the right to change specifications without notice. Please keep the sensors sealed using static shielding bags on storage.The pins of the sensor are plated by Ag. If the sensors expose to an atmosphere, the pins will be black by sulfuration. Please set Zero-calibration function up your products. The offset voltage may be shifted some mechanical stress such as mounting, installation and etc. over longtime using.
