Technical Overview: DSNU-12-30-P-A
The Festo DSNU-12-30-P-A is a compact round cylinder with a 12 mm piston diameter and 30 mm stroke, making it ideal for short, controlled movements in tight spaces. Built according to ISO 6432 standards, this model features a double-acting operation, ensuring efficient push-pull motion powered by compressed air.
The piston rod, threaded with an M6 male end, is made of high-alloy stainless steel for corrosion resistance. The cylinder body is crafted from anodized aluminium, ensuring light weight and strength. Both ends are cushioned with elastic rings/plates to reduce impact and wear, while position sensing is possible via proximity switches.
Operating across a pressure range of 1.5 to 10 bar, the DSNU-12-30-P-A delivers a theoretical forward force of 67.9 N at 6 bar, with return force at 50.9 N. This model is also suitable for cleanroom environments (Class 6 ISO 14644-1) and meets RoHS compliance. It offers CRC 2 corrosion resistance, ensuring reliable use in mildly corrosive industrial conditions.
Applications of DSNU-12-70-P-A in Industrial Automation
The DSNU-12-70-P-A, part of the same Festo DSNU series with a longer 70 mm stroke, is ideal for tasks that need a greater extension range without increasing the cylinder diameter. This makes it perfect for applications like precision part ejection, lightweight lifting, clamping, or gate opening in conveyor systems.
Thanks to its slim design, this cylinder fits easily in machines with restricted space. Maintenance teams can install it in vertical or horizontal orientations using common accessories. The double-acting design allows consistent performance in both directions, improving cycle accuracy in timed operations.
In sectors like electronics, assembly lines, and lab automation, where space is tight and precision is non-negotiable, the DSNU-12-70-P-A enables smooth, reliable, and quiet actuation. Engineers also appreciate its standardized ISO design, which simplifies replacements or upgrades. The combination of low friction, long service life, and easy integration makes this model an intelligent pick for modern automation needs.
