SMC AS Series Speed Controller Speed Controller, M3 M M3 x 0.5 Threaded 4 mm

SMC Series AS Speed Controller, 4mm Outlet size, 1MPa Maximum Operating Pressure - AS1301F-M3-04

This speed controller regulates pneumatic flow to control actuator velocity in automated systems. Designed for threaded installations, it provides a Compact solution for inline adjustment of airflow in industrial environments, operating across a typical temperature span and suitable for moderate-pressure pneumatic circuits.

Features & Benefits

• Brass body with electroless nickel plating resists corrosion and wear
  Inlet thread M3 x0.5 allows secure small-bore connections
  4mm threaded outlet permits direct tubing or fitting attachment
  Operational pressure range 0.1–1 MPa supports varied pneumatic loads
  Withstands proof pressure of 1.5 MPa for transient pressure events
  Rated for temperatures from -5°C to 60°C for diverse ambient conditions

**Applications**

• Suitable for speed regulation of miniature pneumatic cylinders
  Ideal for controlling actuator deceleration in pick-and-place equipment
  Used with pneumatic manifolds in Compact automation panels
  Can be used for flow tuning in instrument Air lines
  Used for valve pilot exhaust flow adjustment in control systems

What connection types are provided for system integration?

The unit features a small M3 inlet thread and a threaded 4mm outlet enabling direct attachment to compatible fittings and tubing.

How does the material choice affect longevity in industrial settings?

A brass construction plated with electroless nickel improves surface hardness and corrosion resistance, reducing maintenance in moist or mildly corrosive atmospheres.

What are the safe operating boundaries for pressure and temperature?

Normal operation is between 0.1 MPa and 1 MPa, with allowable temperatures from -5°C up to 60°C and a proof pressure limit of 1.5 MPa for short-term excursions.

Is this device suitable for hazardous-area installations?

It has no hazardous-area certification and should not be specified where such certification is mandatory.
