SMC Series AS Speed Controller, 12mm Outlet size, 1/2 inches Inlet Connection size - AS4201FS-04-12S
This speed controller regulates pneumatic flow to control actuator motion and cycle timing in industrial systems. It is designed for use where robust materials and consistent performance across a range of pressures and temperatures are required, supporting integration with standard G‑threaded pneumatic fittings for streamlined installation.
Features & Benefits
• Maximum operating pressure 1 MPa for demanding pneumatic circuits
• Proof pressure 1.5 MPa enhances overpressure tolerance
• Operating temperature range -5°C to 60°C for varied environments
• Inlet connection 1/2 in G for common plant compatibility
• Outlet connection 12mm to match metric tubing systems
• Sealing with HNBR and NBR for resilient fluid resistance
• Proof pressure 1.5 MPa enhances overpressure tolerance
• Operating temperature range -5°C to 60°C for varied environments
• Inlet connection 1/2 in G for common plant compatibility
• Outlet connection 12mm to match metric tubing systems
• Sealing with HNBR and NBR for resilient fluid resistance
**Applications**
• Suitable for controlling cylinder retraction speeds in automation lines
• Ideal for flow adjustment on pneumatic conveyors and feeders
• Used with pneumatic valves to fine‑tune motion profiles in assembly cells
• Can be used for speed regulation on pick‑and‑place equipment
• Suitable for maintenance spares in mechanical workshop rigs

What materials contact the medium and how does that help longevity?
Wetted components combine stainless steel, brass and engineered polymers to balance corrosion resistance with wear performance in compressed Air systems.
Which thread standard does the unit use for inlet plumbing?
The inlet employs a G‑threaded 1/2 in connection to match common British and international pneumatic fittings.
How does proof pressure affect safety margins in system design?
A 1.5 MPa proof rating provides a safety buffer above normal working pressure, allowing designers to specify suitable relief devices and test conditions.
Are there approvals indicating restricted substance control?
The product meets RoHS requirements, reducing the presence of regulated hazardous substances in its construction.
