The Festo DSNU-S-12-10-P-A-MQ is a compact double-acting round cylinder from the DSNU-S series, featuring a 12mm bore and 10mm stroke with M5 pneumatic connections. Built with a high-alloy stainless steel piston rod and cylinder barrel, this cylinder is engineered for moderate to demanding environments including cleanroom Class 5 applications. The M5 quick-connect port (MQ suffix) makes installation straightforward in tight spaces where standard G-thread fittings would not fit. It is well suited for food processing, pharmaceutical, packaging, and precision automation applications across industries in Coimbatore and South India.
Note: This product is supplied as a base cylinder unit. Proximity switch sensors, mounting accessories, flow control valves, and push-in fittings must be ordered separately.

The DSNU-S-12-10-P-A-MQ is part of Festo's DSNU-S series of round cylinders — a cleanroom-capable, corrosion-resistant variant of the widely trusted DSNU family. With a 12mm bore and 10mm stroke, this double-acting cylinder is designed for applications where space is at a premium and material quality cannot be compromised. The stainless steel barrel and piston rod, combined with LABS (PWIS)-conformant seals, make it a reliable choice wherever paint contamination or outgassing is a concern.
Key Features
High-alloy stainless steel cylinder barrel and piston rod — Resists corrosion in wash-down environments, humid production areas, and chemical exposure, reducing maintenance intervals significantly.
Cleanroom Class 5 rated (ISO 14644-1) — Measured per ISO 14644-14, making it directly suitable for pharmaceutical, semiconductor, and food-grade automation without additional enclosures.
LABS/PWIS conformant (VDMA 24364-B2-L) — No paint-wetting impairment substances; critical for automotive finishing lines and coating booths where silicone contamination causes defects.
M5 push-in (MQ) pneumatic connection — The MQ suffix denotes a push-in fitting port, allowing quick, tool-free tube connection directly into the port body — ideal for compact panel layouts and rapid assembly.
Double-acting operation — Air pressure drives both advance and return strokes, delivering controlled force in both directions: 67.9 N advance and 50.9 N return at 6 bar.
Elastic cushioning at both ends — Absorbs impact energy (0.07 J rated) at end positions without external shock absorbers, reducing noise and mechanical wear at cycle end.
Wide operating temperature range (−20 °C to +80 °C) — Handles cold-store environments, foundry perimeters, and hot-process packaging lines without seal degradation.
Any mounting position — No orientation restriction simplifies machine design, particularly in multi-axis or rotary transfer systems.
Proximity switch compatible — Cylinder body accepts Festo SME/SMT/SIEN family sensors via accessories for end-of-stroke position feedback without additional sensor brackets.
RoHS compliant and CRC 2 rated — Suitable for moderate corrosion environments, meeting EU and UK material compliance requirements for export-oriented manufacturers.

Common Applications
Pharmaceutical packaging lines — Cleanroom Class 5 rating makes this cylinder directly usable in blister pack, vial capping, and tablet counting automation without special enclosures.
Food and beverage processing — Stainless steel construction and LABS-conformant seals suit wash-down zones in dairy, bakery, and ready-meal processing plants across Tamil Nadu.
Precision assembly machines — The compact 12mm bore and 10mm stroke fit micro-actuation tasks in electronics assembly, PCB handling, and connector insertion jigs.
Textile machinery automation — Used in small gripper and clamp functions on yarn-handling and fabric-cutting machines prevalent in the Coimbatore textile belt.
Automotive component assembly — PWIS conformity ensures no silicone-based contamination risk in paint shop adjacent sub-assembly stations.
Laboratory and LifeTech automation — Suitable for diagnostic equipment, sample handling robots, and medical device assembly where particulate generation must be minimised.
