Technical Specifications of DSNU-20-30-PPS-A
The DSNU-20-30-PPS-A is a high-performance round cylinder built as per ISO 6432 standards. It features a 30 mm stroke and a 20 mm piston diameter, providing a compact yet powerful linear motion solution. The piston rod has an M8 male thread, allowing easy connection with mechanical linkages. This double-acting cylinder operates effectively within 1 to 10 bar pressure range using clean, dry compressed air conforming to ISO 8573-1:2010 [7:4:4].
A key feature is its self-adjusting pneumatic end-position cushioning, which automatically adapts to varying loads and speeds—minimizing shock and ensuring smooth stops without manual adjustment. The pneumatic port is G1/8, supporting standard fittings. It also supports position detection via proximity switches, enabling feedback control in automation systems. Materials include high-alloy stainless steel for the piston rod and barrel, and anodised aluminium for the cover—making it corrosion-resistant (CRC class 2) and suitable for moderate industrial environments. It is RoHS-compliant and supports cleanroom use (Class 6).
Application Use Case: DSNU-12-70-P-A in Action
The Festo DSNU-12-70-P-A is well-suited for tasks that require longer stroke lengths in tight spaces without compromising precision. One typical use case is in semiautomatic assembly lines, where parts need to be consistently pushed, clamped, or positioned. The 70 mm stroke offers adequate range to perform these repetitive tasks reliably.
In packaging machines, this model is commonly used to drive cutting blades, press mechanisms, or product diverters. Its double-acting configuration ensures smooth forward and return strokes, while its compact design helps fit into dense machine layouts. It can also be equipped with proximity sensors, allowing accurate stroke monitoring and improved synchronization with the control system.
For engineering students, the DSNU-12-70-P-A is often featured in mechatronics labs to demonstrate the basics of pneumatic actuation. For maintenance engineers, it is a dependable replacement in cases of wear or failure, thanks to its standard dimensions and compatibility with ISO 6432 accessories. Whether for a new project or preventive maintenance, this cylinder delivers consistent results across a wide range of applications.
