SMC Series AS Speed Controller, 1/2 inches Inlet size, 10mm Outlet size - AS4301F-04-10SA

This speed controller regulates pneumatic actuator velocity by controlling airflow between an R standard male inlet and a tube outlet. It is suited to industrial automation environments where controlled motion is required and connects directly to a 10mm one-touch tube for straightforward integration.

Features & Benefits

• Operates across a pressure range of 0.1–1 MPa, enabling precise flow adjustment
• Withstands up to 1.5 MPa proof pressure for occasional overpressure events
• Serviceable between −5°C and 60°C for varied plant conditions
• Constructed from polybutylene terephthalate and brass for chemical and mechanical compatibility
• Complies with ISO 4414 to support standard pneumatic safety practices

Applications

• Suitable for speed modulation on pneumatic cylinders in assembly lines
• Ideal for conveyor feed-rate control in material handling systems
• Used with valve manifolds in automation test rigs
• Can be used for precise actuator deceleration in robotic tooling

What inlet connection does it require for installation?

It accepts a 1/2 in R male threaded inlet compatible with R-thread fittings.

How is the outlet connected to existing pneumatic tubing?

The outlet uses a 10mm one-touch fitting that allows a quick push-in connection to soft tube.

Which industry standards are relevant to its selection?

It meets JIS B 8370 and ISO 9001 requirements and aligns with RoHS directives for material restrictions.

What materials contact the process Air and what does that imply?

The Air path includes polybutylene terephthalate and brass components, offering a balance of polymer corrosion resistance and metal strength.
