Festo is a world-renowned German brand known for its innovation in pneumatic and electrical automation technologies. With a presence in over 60 countries, Festo products are used across manufacturing, process automation, packaging, and factory maintenance. Their components are trusted for their build quality, ease of integration, and global standard compliance. Engineers, technicians, and maintenance professionals worldwide rely on Festo for reliable, high-precision motion control solutions that stand up to tough industrial environments.
The Festo DSNU-12-150-P-A is a high-quality, ISO 6432-compliant round cylinder designed for consistent performance in linear motion applications. It offers a stroke length of 150 mm with a 12 mm piston diameter, making it suitable for tasks that require extended linear travel. The M6 male thread piston rod is double-acting, powered by compressed air within an operating pressure range of 1.5 to 10 bar. The cylinder features elastic cushioning rings at both ends for smooth deceleration and reduced wear. It is compatible with proximity switches for position sensing and can be mounted using various accessories. Built from high-alloy stainless steel and anodized aluminium, the cylinder resists corrosion and meets RoHS and cleanroom class 6 standards, making it safe and compliant for sensitive environments. It delivers a theoretical force of 67.9 N (advance) and 50.9 N (return) at 6 bar, offering strong actuation for compact equipment.
Where and Why the DSNU-12-150-P-A is Used in Industry
The DSNU-12-150-P-A is ideal for applications that need longer and precise linear strokes—without compromising on size or durability. In automatic testing machines, it helps push or retract parts gently and accurately over a 150 mm range. In labelling, sorting, or packaging lines, the extended stroke supports movement across wider sections or conveyors. Its clean and corrosion-resistant body makes it a preferred choice for pharmaceutical, electronics, and food-grade machinery, where hygiene and material compliance are critical. With position detection support, engineers can integrate it into semi-automated setups for feedback and control. From factory floor upgrades to new machine builds, this Festo cylinder helps maintenance teams and designers achieve longer reach, reliable actuation, and smooth motion—without increasing system complexity.
