DU20-40D Penumatic cylinder

Model Code Breakdown

• C: Built-in magnetic ring for auto-switch position sensing.
• DU: Double-acting, single-rod free mount cylinder configuration.
• 20: \(20\text{ mm}\) piston bore diameter.
• 40: \(40\text{ mm}\) stroke displacement length.
• D: Double-acting operation (air pressure drives both extension and retraction). 

Core Technical Specifications

• Body Material: High-durability extruded
• Cushioning: Standard built-in rubber bumpers at both stroke ends to absorb impact.
• Maximum Piston Speed: Up to \(500\text{ mm/s}\).
• Port Thread: standard \(M5 \times 0.8\) pneumatic connection ports.
• Maximum Operating Pressure: \(0.7\text{ MPa}\) (\(7\text{ bar}\)) to \(1.0\text{ MPa}\) (\(10\text{ bar}\)) depending on system setup. 

Key Benefits & Use Cases

• Multi-Surface Mounting: Can be mounted via through-holes on multiple flat surfaces, eliminating the need for bulky specialized mounting brackets.
• Position Tracking: Features integrated switch slots, making it fully auto-switch capable for remote PLC position confirmation.
• Compact Footprint: Ideal for pick-and-place automation, material handling, assembly fixtures, and tight industrial packaging machinery.
