SMC AS2001F-04D SPEED CONTROLLER

Series AS tamper proof and screw driver adjustment series speed controllers are available in elbow, universal or in-line models. Both the screw driver and tamper proof types prevent inadvertent operation but the tamper proof type offers extra protection by requiring a special tool for adjustments. Series AS is suitable for use in clean rooms where dust from discoloration and rusting of copper materials is unacceptable.
