DSNU-12-40-P-A – Slim Design, Precise Stroke Control
The Festo DSNU-12-40-P-A is a compact round cylinder with a 12 mm piston diameter and a 40 mm stroke, designed according to ISO 6432 standards. It operates on compressed air, with a double-acting mechanism, allowing both extend and retract strokes to be controlled with precision. The piston rod features an M6 male thread, enabling easy connection with end-effectors or fixtures.
Built for flexibility, this cylinder supports optional mounting positions and includes elastic cushioning rings at both ends for reduced shock during operation. It supports position sensing via proximity switches, adding control accuracy. The use of high-alloy stainless steel for the piston rod and anodised aluminium for the cover ensures durability and corrosion resistance (CRC 2), making it suitable for a range of environments, including cleanrooms (Class 6 ISO 14644-1).
Operating pressure ranges from 1.5 to 10 bar, and at 6 bar, it generates a theoretical force of 67.9 N (advance) and 50.9 N (return). It’s a RoHS-compliant product with a compact mass profile, making it a solid fit for lightweight yet precise actuation tasks.
Application Insight: Festo DSNU-12-70-P-A in Industrial Setups
The DSNU-12-70-P-A, with its longer stroke length of 70 mm, offers greater reach for tasks that involve extended motion without increasing cylinder diameter. It is particularly useful in setups where components need to be moved, pushed, or positioned with higher flexibility—such as clamping mechanisms, light-duty material transfer, and indexing operations on small automation cells.
Maintenance teams often install this model in pick-and-place systems, pneumatic fixtures, and inspection lines, where space is limited but precise motion is essential. Its standard ISO form factor makes replacement and integration easier across different brands and machine types.
What sets this cylinder apart is its balance of size and performance—it delivers consistent force, handles moderate pressure ranges, and fits snugly into machines without adding bulk. It also works reliably over thousands of cycles, reducing downtime and improving machine availability. For teams looking for a cost-effective and technically sound solution, the DSNU-12-70-P-A represents a smart investment in day-to-day plant operations.
