※ Current consumption, Response time: It may differ depending on the models. For more information, see the "SFL/SFLA User Manual." ※ Load voltage of Safety related output: The values of load voltage were drawn with PNP output, and in case of NPN output, apply these in reverse. ※ Load current of Safety related output: Be sure that the load current should be greater than 6 mA ※ Residual voltage of Safety related output: The residual voltage was drawn with 300 mA of load current. ※ Auxiliary output, Lamp output: It is the non-safety output. Do not use it for safety purposes. ※ Approved certification protection ratings are IP65 and IP67. ※ The certified models for S-mark and KCs (industrial robot protection device) have the same functional basis
