SMC Series AS Speed Controller, 1/2 inches Inlet Connection size, 16mm Outlet Connection size - AS4201FS-04-16S


This speed controller regulates airflow to control actuator velocity in pneumatic systems. Designed for industrial automation contexts, it connects via a 1/2 inches G inlet and delivers controlled flow through a 16mm threaded outlet. Constructed from a combination of polymers, metals and elastomers, it operates within typical shop and factory temperature and pressure ranges.

Features & Benefits


• Maximum operating pressure 1MPa enables robust system performance
• Proof pressure 1.5MPa provides resistance to transient overpressure
• Operating temperature range -5°C to 60°C supports varied environments
• NBR and HNBR Seals reduce Air leakage and chemical wear
• Brass electroless nickel-plated components resist corrosion in pneumatics

**Applications**


• Suitable for flow control on conveyor cylinder speed adjustment
• Ideal for use in pick-and-place actuator timing
• Used with pneumatic grippers to manage closing velocity
• Can be used for cylinder cushioning in assembly machines

What connection standards are required for installation?


It requires a 1/2 inches G threaded inlet compatible with G-thread fittings and a 16mm threaded outlet for downstream tubing or fittings.

Which materials contact the pneumatic medium and what are their advantages?


Sealing materials include nitrile and halogenated nitrile rubbers for wear and chemical resistance while internal components use brass, stainless steel and engineered plastics to balance durability and friction control.

What standards does it adhere to for machine safety and electrical considerations?


The unit conforms to recognised industry standards covering pneumatic and electrical safety practices as listed in its technical approvals.

How should the unit be selected for systems with variable pressure?


Choose it where nominal supply does not exceed 1MPa and allow for a 1.5MPa proof pressure margin to accommodate pressure transients.
