SMC Series AS Speed Controller, 1/2 inches Inlet size, 12mm Outlet size - AS4201FG-04-12S


This speed controller regulates Airflow to control actuator motion in pneumatic systems. It is intended for industrial automation and mechanical applications where controlled Air flow and consistent operation are required. Constructed from stainless steel and polybutylene terephthalate, it is suitable for installations requiring robust wetted parts and disciplined flow adjustment within typical pneumatic networks.

Features & Benefits


• Maximum operating pressure 1.0MPa for demanding pneumatic circuits
• Proof pressure 1.5MPa enhances transient pressure tolerance
• Minimum operating pressure 0.1MPa ensures function at low supply pressures
• Operating temperature range -5°C to 60°C supports varied plant environments
• 1/2 inches R male inlet simplifies connection to standard R-threaded piping
• 12mm one-touch female outlet enables fast tube installation

**Applications**


• Suitable for controlling cylinder speed in assembly line automation
• Ideal for flow regulation in compressed-air distribution panels
• Used with pick-and-place actuators to tune end-of-stroke deceleration
• Can be used for machine tool auxiliary pneumatic circuits
• Used for regulating feed speed in packaging equipment

What materials contact the airflow and how do they affect longevity?


The internal flow path uses stainless steel for corrosion resistance while polybutylene terephthalate components provide lightweight, wear‑resistant sealing interfaces.

How does the connection configuration aid installation?


The inlet uses a 1/2 inches R male thread compatible with R‑standard fittings and the outlet accepts a 12mm one‑touch tube for Rapid line changes without tools.

What standards relate to its operational and management practices?


The product aligns with ISO 4414 and JIS B 8370 for pneumatic system guidelines and is manufactured under ISO 9001 and ISO 14001 frameworks with RoHS considerations.

How does the device behave under pressure excursions?


It is rated to operate up to 1.0MPa and withstand short‑term pressure peaks up to 1.5MPa as a proof pressure limit.
