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

• Pneumatic Cushioning:​ Adjustable cushioning at both ends for smooth end-position damping

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

• Male Thread Piston Rod:​ M6 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

• Lightweight Construction:​ Optimized for medium-duty applications

Technical Specifications

Note: Specifications are based on FESTO DSNU series technical documentation and industry standards. The exact configuration for this specific model number includes 16mm bore, 40mm stroke, pneumatic cushioning, and male thread piston rod.

Model Number Decoding (DSNU-16-40-PPV-A)

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

• 16:​ Bore diameter (16 mm)

• 40:​ Stroke length (40 mm)

• PPV:​ Cushioning type (PPV = pneumatic cushioning, adjustable at both ends)

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

Note:​ The "PPV" designation indicates pneumatic cushioning with 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-16-40-PPV-A:​ 16mm bore, 40mm stroke, pneumatic cushioning, position sensing (this model)

• DSNU-20-40-PPV-A:​ 20mm bore with same stroke (higher force output)

• DSNU-12-40-PPV-A:​ 12mm bore with same stroke (lower force output)

• DSNU-16-25-PPV-A:​ Same bore but 25mm stroke (shorter travel)

• DSNU-16-60-PPV-A:​ Same bore but 60mm stroke (longer travel)

• DSNU-16-40-P-A:​ Same bore and stroke but elastic cushioning (different cushioning type)

The 16mm bore​ provides moderate force output for medium-duty applications, while the 40mm stroke​ offers compact travel distance suitable for applications with limited space requirements.

Typical Applications

• Industrial Automation:​ Part positioning and clamping in assembly lines

• Material Handling:​ Conveyor and sorting system actuation

• Packaging Machinery:​ Product positioning and ejection operations

• Clamping Devices:​ Workpiece clamping in fixture applications

• Valve Actuation:​ Operating valves in process control systems

• Testing Equipment:​ Linear actuation in test stands

• General Automation:​ Medium-duty linear motion applications

Important Selection & Installation Notes

1. Bore Size Consideration:​ The 16mm bore provides approximately 120N force at 6 bar. Ensure this meets your application's force requirements. For higher force, select 20mm or larger bore sizes; for lower force, consider 12mm models.

2. Stroke Consideration:​ The 40mm stroke provides moderate travel distance. Ensure this meets your application's movement requirements. For shorter strokes, select 25mm models; for longer strokes, consider 60mm or longer.

3. Cushioning Performance:​ Pneumatic cushioning provides adjustable end-position damping. For applications with high speeds, ensure cushioning is properly adjusted.

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 120N 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 makes this model suitable for applications with limited installation space.

12. Air Consumption:​ Ensure your compressed air system can supply sufficient flow rate for the application.
