    1. Precautions for Design Warning 1. Confirm the specifications. Give careful consideration to the operating conditions, such as the application, fluid, and environment, and use within the specified operating ranges. If the product is used beyond the specification range, this may cause the product to break or malfunction. SMC does not guarantee against any damage if the product is used outside of the specification range.

    Caution 1. Power saving circuit The power saving circuit (PWM control) built into the product reduces power consumption via high- speed switching operation with the PWM control circuit after the rated voltage has been applied for approx. 200 ms when energized. Please note that the effect of this PWM control can cause the following problems depending on the type of switch and drive circuit used.
