Technical Overview

The Festo DSM-T-12-270-CC-FW-A-B (Part Number: 1145089) is a high-performance double-acting semi-rotary drive designed for precision automation tasks. Featuring a tandem rotary vane design with a 12mm size, this actuator provides a configurable swivel angle up to 246 degrees and delivers a robust theoretical torque of 2.5 Nm at 6 bar operating pressure. It incorporates pneumatic shock absorbers at both ends for smooth deceleration and reliable end-position cushioning. Built with a nickel-plated steel flanged drive shaft and a wrought aluminum alloy housing, it is optimized for industrial durability. Additional features include an M5 pneumatic connection, compatibility with proximity sensors for exact position feedback, and reliable operation within a 2.5 to 10 bar pressure range.

Industrial Applications

1. Automated Packaging Gate Diverters

Actuates precision routing gates in packaging conveyors to redirect items to alternative processing lines.

Problem Solved

Standard rotary actuators struggle with fast cycling speeds; this unit provides a 1.5 Hz swivel frequency at 6 bar to enable high-throughput sorting.

2. Precision Robotic Pick-and-Place Tooling

Drives the rotational axis of grippers on pick-and-place robots for orienting parts before insertion.

Problem Solved

Heavy actuators reduce overall robot payload capacity. The lightweight 390g aluminum construction and robust 2.5 Nm torque provide an optimal power-to-weight ratio.

3. Automated Component Inspection Stations

Rotates manufactured parts in front of machine vision cameras for full 360-degree quality control scanning.

Problem Solved

Ensures the camera captures clear, blur-free images by stopping the part precisely using the 0.1° repetition accuracy and integrated position sensing.
