DSNU-12-50-P-A – Compact Yet Capable Pneumatic Cylinder
The DSNU-12-50-P-A is a round, double-acting pneumatic cylinder with a stroke of 50 mm and a piston diameter of 12 mm. Designed according to ISO 6432 standards, this model is ideal for compact installations that demand reliable linear motion. It features a male-threaded M6 piston rod, which makes it easy to connect with mechanical linkages or fixtures.
The cylinder operates effectively between 1.5 to 10 bar, and at 6 bar pressure, it delivers 67.9 N of advance stroke force and 50.9 N in the return stroke. Its elastic cushioning rings reduce impact energy at both ends, ensuring smoother operation and lower wear. It’s position sensor compatible, RoHS-compliant, and suitable for Class 6 cleanroom environments.
With high-alloy stainless steel used in both the piston rod and barrel, and an anodised aluminium cover, this cylinder ensures long service life even in mildly corrosive environments (CRC 2). The cylinder is lightweight yet durable, with a total build optimized for automation setups that demand speed, accuracy, and endurance.
Where DSNU-12-70-P-A Excels in Real-World Applications
The Festo DSNU-12-70-P-A extends the same design with a 70 mm stroke, offering more reach in motion-critical applications. This additional stroke length is highly useful in fixture unlocking, light-duty part ejection, and packaging systems where components must travel further distances within limited machine dimensions.
Its precise movement and compact body make it a strong fit for conveyor systems, testing jigs, and machine doors, especially when controlled movement is needed without overloading the structure. Engineers prefer this model in automated testing benches where part detection, inspection, and indexing happen in sequence and require dependable actuation.
What makes the DSNU-12-70-P-A popular is its balance—enough force to move components, longer reach for mechanical flexibility, and minimal maintenance due to its robust material selection. Whether you're maintaining existing lines or building new automation cells, this Festo cylinder helps ensure smooth operation, extended uptime, and consistent performance under Indian industrial conditions.
