SMC Series AS Speed Controller, 12mm Outlet size, 1/2 inches Inlet Connection size - AS4301F-04-12S
This speed controller is a Compact pneumatic device designed to regulate Air flow within automation systems. It controls actuation speed in equipment using a threaded R inlet and a push-fit outlet, operating across typical industrial temperature and pressure ranges to support controlled motion in mechanical and electrical assemblies.
Features & Benefits
• 1/2 inches R inlet enables straightforward connection to standard pipework
• 12mm one-touch outlet allows Rapid tube insertion and removal
• Polybutylene terephthalate and brass construction offers chemical and wear resistance
• Operating pressure range 0.1–1MPa supports a wide range of actuator forces
• Maximum operating temperature 60°C maintains performance in warmed environments
• Proof pressure 1.5MPa provides margin against pressure spikes
• 12mm one-touch outlet allows Rapid tube insertion and removal
• Polybutylene terephthalate and brass construction offers chemical and wear resistance
• Operating pressure range 0.1–1MPa supports a wide range of actuator forces
• Maximum operating temperature 60°C maintains performance in warmed environments
• Proof pressure 1.5MPa provides margin against pressure spikes
**Applications**
• Suitable for speed control of pneumatic cylinders in production lines
• Ideal for integration into pick-and-place actuator circuits
• Used with pneumatic valves for motion dampening in assembly stations
• Can be used for flow adjustment in lab automation rigs

What inlet thread type does it accept for piping connections?
It uses a male R thread conforming to the R standard for tapered pipe fittings.
Which materials contact the media and what is their advantage?
The body combines polybutylene terephthalate with brass components to balance lightweight polymer properties with metal durability at connection points.
What pressure scenarios can it safely handle during operation?
Normal working pressure spans from 0.1MPa up to 1MPa, with short-term testing to 1.5MPa for proofing against overpressure events.
How is the outlet connected to tubing in system layouts?
The outlet employs a female one-touch tube fitting sized for 12mm tubing, permitting quick assembly and disassembly without tools.
