Product Description
Festo DSNU-S-12-60-P-A-MQ – Compact Stainless Steel Round Cylinder Overview
The Festo DSNU-S-12-60-P-A-MQ belongs to the DSNU-S series of ISO-compliant round cylinders, designed for applications where a small footprint, stainless construction, and cleanroom compatibility must coexist. With a 12 mm piston bore and 60 mm stroke, this double-acting cylinder delivers reliable linear motion in confined machine envelopes without sacrificing durability or media compatibility. The stainless steel barrel and rod, combined with LABS (PWIS)-conformant materials, make it particularly well matched to food-grade and life-science automation lines.Key Features
- High-alloy stainless steel barrel and piston rod — resists process media, washdowns, and mild chemical exposure; suitable for CRC 2 corrosion environments without additional protection.
- ISO Class 5 cleanroom suitability (ISO 14644-14) — independently measured; qualifies this cylinder for pharmaceutical filling lines, medical device assembly, and semiconductor handling.
- LABS / PWIS conformity (VDMA 24364-B2-L) — paint-wetting-impairment-substance-free construction ensures use near paint booths and coating stations without contamination risk.
- Double-acting operation — positive force in both advance and return strokes; advance force 67.9 N and return force 50.9 N at 6 bar — reliable even in vertical or inverted mounting.
- Elastic cushioning rings at both ends — absorbs end-of-stroke impact (0.07 J rated) without need for external shock absorbers on low-load applications, reducing system complexity.
- Any mounting position — no orientation restriction; integrates into horizontal, vertical, or angled actuator brackets without design rework.
- M5 pneumatic connection — compact port size consistent with the 12 mm bore class; pairs directly with Festo QSM-M5 push-in miniature fittings for clean, tool-free tubing connections.
- RoHS compliant materials — safe for export to EU markets and compliant with electronics-adjacent machine builds.
- Proximity switch-ready groove — compatible with Festo SME/SMT series sensors; enables position feedback without any barrel modification.
- Wide ambient temperature range: -20 °C to +80 °C — functional in cold stores, oven-adjacent stations, and outdoor enclosures without special sealing upgrades.
