DSNU-12 (193988) – Technical Features and Build Quality
The Festo DSNU-12 round cylinder is engineered to perform reliably in a wide range of pneumatic applications. It features a 12 mm piston diameter and supports strokes ranging from 1 mm up to 200 mm, offering flexibility for compact and extended motion. The cylinder includes elastic cushioning and adjustable pneumatic cushioning at both ends, allowing smooth deceleration based on load and speed.
This model conforms to ISO 6432 standards and includes variants such as low-friction versions, corrosion-resistant types, heat-resistant seals (up to 120°C), and ATEX-certified versions for explosive zones (Zone 1, 2, 21, and 22). Its RoHS-compliant stainless steel piston rod and cylinder barrel ensure long-term durability even in corrosive environments. With a CRC rating of 2 or 3, it is ideal for environments with moderate to high corrosion stress.
It uses an M5 pneumatic connection, supports position detection via proximity switches, and includes advanced design options like square piston rod for anti-rotation, axial/lateral ports, and direct mounting support—making it highly adaptable to various design needs.
Where is DSNU-12-70-P-A Used in Real-World Applications?
The DSNU-12-70-P-A cylinder is particularly useful in precise, controlled applications that require mid-range stroke length and clean, smooth motion. For example, in small part assembly lines, it can push, lift, or align components with accuracy. It is commonly seen in pick-and-place systems, valve actuators, carton flaps, and product ejection setups.
Thanks to its position sensing compatibility, it can integrate with feedback-based PLC systems—helping engineers monitor every stroke in real-time. The cylinder is also well-suited for explosive or sensitive zones, such as paint booths, pharmaceutical packing rooms, and ATEX-regulated industries, due to its certified ignition protection and temperature resistance.
For new engineers and students, the DSNU-12 series serves as an ideal example of a versatile ISO round cylinder—demonstrating how modular accessories and variant options allow one product series to serve multiple industrial needs.
