FESTO DSNU-20-10-P-A ISO Cylinder

The FESTO DSNU-20-10-P-A​ is a compact double-acting pneumatic cylinder​ from the DSNU series, featuring 20mm bore diameter​ and 10mm stroke. This ISO 6432 compliant cylinder is designed for industrial automation applications requiring reliable linear motion with elastic cushioning. With compact design, male thread piston rod, and compatibility with proximity sensors, it provides precise performance for applications in packaging, assembly, and precision handling systems where short stroke and compact size are critical.

Key Features

• ISO 6432 Compliance:​ Standardized dimensions and mounting for easy integration

• Double-Acting Operation:​ Provides force in both extension and retraction directions

• Elastic Cushioning:​ Elastic cushioning rings/plates at both ends for end-position damping

• Compact Design:​ Small footprint for space-constrained applications

• Male Thread Piston Rod:​ M8 external thread for accessory mounting

• Position Sensing Compatible:​ Supports proximity sensor installation (requires magnetic piston)

• Wide Operating Pressure:​ 0.1 to 10 bar operating range

• Standard Mounting:​ Multiple mounting options with accessories

• Short Stroke Design:​ 10mm stroke for applications requiring minimal travel

Technical Specifications

Note: Specifications are based on FESTO DSNU series technical documentation and industry standards. The exact configuration for this specific model number includes 20mm bore, 10mm stroke, elastic cushioning, and male thread piston rod.

Model Number Decoding (DSNU-20-10-P-A)

• DSNU:​ Series designation (Standards-based cylinder, double-acting)

• 20:​ Bore diameter (20 mm)

• 10:​ Stroke length (10 mm)

• P:​ Cushioning type (P = elastic cushioning rings/plates at both ends)

• A:​ Position sensing capability (A = compatible with proximity sensors)

Note:​ The "P" designation indicates elastic cushioning with non-adjustable end-position damping. The "A" specifies position sensing compatibility (requires magnetic piston for sensor operation).

Key Differences from Similar Models

Compared to other DSNU series cylinders:

• DSNU-20-10-P-A:​ 20mm bore, 10mm stroke, elastic cushioning, position sensing (this model)

• DSNU-16-10-P-A:​ 16mm bore with same stroke (lower force output)

• DSNU-25-10-P-A:​ 25mm bore with same stroke (higher force output)

• DSNU-20-25-P-A:​ Same bore but 25mm stroke (longer travel)

• DSNU-20-10-PPV-A:​ Same bore and stroke but pneumatic cushioning (different cushioning type)

• DSNU-20-10-PPS-A:​ Same bore and stroke but self-adjusting pneumatic cushioning

The 20mm bore​ provides moderate force output for medium-duty applications, while the 10mm stroke​ offers minimal travel distance for applications requiring precise positioning with limited movement.

Typical Applications

• Precision Clamping:​ Workpiece clamping and positioning in fixture applications

• Valve Actuation:​ Operating small valves in process control systems

• Short-Stroke Positioning:​ Applications requiring minimal linear movement

• Assembly Equipment:​ Component insertion and positioning with precise movement

• Testing Fixtures:​ Actuation in test stands and measurement equipment

• Compact Automation:​ Space-constrained applications requiring linear motion

• General Automation:​ Medium-duty applications with short stroke requirements

Important Selection & Installation Notes

1. Bore Size Consideration:​ The 20mm bore provides approximately 188N force at 6 bar. Ensure this meets your application's force requirements. For higher force, select 25mm or larger bore sizes; for lower force, consider 16mm or 12mm models.

2. Stroke Consideration:​ The 10mm stroke provides minimal travel distance. Ensure this meets your application's movement requirements. For longer strokes, select 25mm, 40mm, or longer models.

3. Cushioning Performance:​ Elastic cushioning provides non-adjustable end-position damping. For applications with high speeds, ensure the cushioning is adequate for your application.

4. Operating Pressure:​ Do not exceed 10 bar maximum operating pressure. For optimal performance, operate between 4-6 bar.

5. Air Quality:​ Use filtered, lubricated or non-lubricated compressed air according to ISO 8573-1:2010 [7:4:4]. If using lubricated air, maintain consistent lubrication.

6. Mounting:​ Ensure proper alignment during installation to avoid side loads, which can reduce seal life and cause premature failure.

7. Position Sensing:​ This model is compatible with proximity sensors for position detection. Ensure the piston has a magnetic ring (standard on most DSNU models) if position sensing is required.

8. Force Requirements:​ With 188N maximum force at 6 bar, this cylinder is suitable for medium-duty applications. Verify load requirements and safety factors.

9. Temperature Range:​ Do not operate outside -20°C to +80°C range.

10. Maintenance:​ Regular inspection of seals is recommended. Check for air leaks and proper cushioning performance periodically.

11. Space Constraints:​ The compact size and short stroke make this model suitable for applications with extremely limited installation space.

12. Short Stroke Consideration:​ The 10mm stroke is ideal for applications requiring minimal movement. For longer travel requirements, select models with longer strokes.
