Festo DSNU-S-12-30-P-A-MQ – Round Cylinder | Bore 12mm, Stroke 30mm | Murali Pneumatics Coimbatore

Festo DSNU-S-12-30-P-A-MQ – Stainless Steel Round Cylinder, Bore 12mm × Stroke 30mm

Key Features

• High-alloy stainless steel cylinder barrel and piston rod — Provides CRC 2 moderate corrosion resistance, suitable for humid, washdown, and mildly chemical environments without surface degradation.
• Cleanroom Class 5 per ISO 14644-1 — Measured according to ISO 14644-14; meets the outgassing and particle emission standards required for pharmaceutical and electronics assembly environments.
• Double-acting operation — Positive force on both advance and return strokes; advance force 67.9 N and return force 50.9 N at 6 bar, giving reliable bidirectional actuation.
• Elastic cushioning rings/plates at both ends — Absorbs end-position impact energy (rated 0.07 J) without additional external shock absorbers, reducing noise and mechanical wear in high-cycle applications.
• M5 pneumatic connection — Compact port sizing consistent with the 12mm bore; simplifies tubing routing in space-constrained machine designs.
• TPE-U (polyurethane) seals — Excellent wear resistance and low friction, supporting long service life even in lubricated or unlubricated compressed air systems.
• Position sensing ready — Compatible with proximity switches mounted via accessories; no built-in T-slot, sensor mounting is through the designated accessory system.
• LABS (PWIS) conformity to VDMA 24364-B2-L — Safe for use in paint spray environments; no paint-wetting impairment substances that could cause surface defects on painted components nearby.
• Wide operating temperature range: −20 °C to +80 °C — Handles both cold-room conveyor applications and elevated-temperature process environments without seal degradation.
• RoHS compliant — Meets EU and international requirements on restriction of hazardous substances in electrical and electronic equipment supply chains.

Technical Specifications

Common Applications

• Food and beverage packaging lines — Stainless steel construction and cleanroom rating make this cylinder ideal for portioning, sealing, and labelling machinery subject to regular washdown cycles in Coimbatore food processing units.
• Pharmaceutical blister pack and tablet press automation — Class 5 cleanroom compliance and LABS conformity meet the stringent particle and outgassing requirements of pharma production environments.
• Textile and spinning machinery — Compact 12mm bore fits within tight actuator pockets in winding frames, bobbin changers, and thread tensioning mechanisms widely used across Coimbatore's textile industry.
• Printing and paper handling equipment — Short 30mm stroke with reliable cushioning provides precise paper clamping, registration, and diverter actuation without damaging sensitive substrates.
• Plastic injection moulding auxiliaries — Core pull and ejector pin assist mechanisms benefit from the stainless rod's resistance to mould release agents and elevated mould environment temperatures up to 80 °C.
• Electronics and semiconductor assembly — Cleanroom Class 5 rating makes this cylinder suitable for pick-and-place, component pressing, and board handling in controlled manufacturing cells.
