Motorised Rollers (MDR)

32mm PM320HS 24VDC Motor Driven Roller with external controller

The PM320HS motorised roller is designed for applications in distribution and assembly lines, specifically used in belt conveyors conveying very light loads, for weighing, feeding, and evacuation of parts. Available from a length of 170mm, the PM320HS is the shortest motor driven roller on the market, allowing the design of very compact roller conveyors. The controller is separated from the gear-motor in order to optimise the performance and durability of the roller. The assembly can be used independently or controlled by PLC.

Unmatched Compactness. With a diameter of just 32mm and tube lengths starting at 170mm, this is the ideal solution for miniaturised conveyors and tight machinery spaces.

Stainless Steel Construction. Built with a stainless steel 304L tube and 303L shafts/flanges, ensuring durability and corrosion resistance for clean environments.

Optimised for Belt Conveyors. Specifically engineered to drive thin, elastic belts for smooth transport of small, light items in processing or distribution workflows.

Dyno Conveyors is a proud partner and exclusive distributor of Itoh Denki, the Japanese world-leading specialist in motorised drive roller (MDR) based material handling technologies.

Features, Benefits & Uses

Features & Benefits

  • Space Saving Design. The small diameter and short length options allow for the creation of low-profile, lightweight conveyor modules.
  • Operational Durability. The external circuit board (CB018S) isolates electronics from motor heat, ensuring consistent performance and longevity.
  • Safety & Protection. Operates on 24VDC with integrated thermal protection for both the circuit board (>75°C) and protection against induced voltage.
  • Environmental Protection. Rated IP65 (dust tight and protected against water jets, though high-pressure washing is not recommended), making it suitable for various industrial environments.
  • Precise Control. Offers 8 fixed speeds ranging from 6 to 30 m/min when paired with the dedicated controller.

Uses

  • Small belt conveyors for light goods.
  • Weighing and feeding stations.
  • Evacuation of small parts in distribution or assembly.
  • Machinery with limited installation space.
