Compact Actuation for Space-Constrained Automation
The Festo ADN-16-35-A-P-A (manufacturer ID 8178762) is a double-acting pneumatic cylinder designed for applications where installation space is limited but performance cannot be compromised. With a 16 mm piston diameter and a 35 mm stroke, this unit delivers a theoretical advancing force of 121 N and a retracting force of 90 N at 6 bar. Its compact footprint and low product weight of 124 g make it an excellent choice for pick-and-place units, clamping devices, and small assembly fixtures where every millimeter counts.
The cylinder is built to ISO 21287, ensuring dimensional interchangeability and compliance with widely accepted standards. The piston rod features an M6 external thread, and the pneumatic connection is M5, allowing straightforward integration with standard fittings and tooling. The moving mass is only 32 g, which contributes to fast response times and reduced inertia in high-cycle applications.
Elastic Cushioning for Smooth End-of-Stroke Operation
Equipped with elastic cushioning rings and pads at both ends, the ADN-16-35-A-P-A absorbs impact energy up to 0.15 J at the end positions. This cushioning system minimizes mechanical shock, reduces noise, and protects the cylinder and connected components from premature wear. For engineers designing high-speed or high-frequency operations, this feature translates into longer service life and lower maintenance costs.
The cylinder operates with compressed air per ISO 8573-1:2010 [7:4:4] and can be used with oil lubrication if required for downstream processes. Its ambient temperature range of -20°C to 80°C allows deployment in both cold and moderately hot environments, making it versatile across different production floors.
Position Sensing and Mounting Flexibility
This model is prepared for proximity sensor mounting, enabling reliable end-position detection without the need for mechanical switches. The sensor-ready design simplifies integration into automated control systems, providing real-time feedback for sequencing and safety interlocks. The mounting position is unrestricted, and the cylinder can be installed in any orientation, offering layout flexibility for machine builders.
Mounting options include through-holes, internal threads, or the use of accessories, allowing designers to choose the most suitable method for their specific frame or bracket. This adaptability reduces the need for custom adapters and speeds up mechanical assembly.
Material Quality and Environmental Compliance
Festo uses high-quality materials to ensure durability and consistent performance. The cylinder barrel and covers are made of anodized wrought aluminum alloy, providing a corrosion-resistant surface suitable for moderate industrial environments (CRC 2). The piston rod is high-alloy steel, offering strength and resistance to bending under lateral loads. Seals are made of TPE-U (PUR), known for their wear resistance and low friction.
The product is RoHS-compliant and meets LABS (PWIS) conformity to VDMA24364-B1/B2-L, making it suitable for use in paint shops and other applications where silicone-free materials are mandatory. Additionally, it is rated for cleanroom class 6 according to ISO 14644-1, expanding its applicability to electronics assembly and pharmaceutical packaging.
Selection Considerations and Integration Value
When selecting the ADN-16-35-A-P-A, engineers should verify that the force and stroke meet the application's requirements. The theoretical forces at 6 bar are 121 N advancing and 90 N retracting, which should be sufficient for light to medium duty tasks. The elastic cushioning is ideal for moderate speeds; for high kinetic energy applications, alternative cushioning options may be required.
This cylinder is part of a family with over 350 variants, allowing procurement teams to standardize on a single platform while accommodating different strokes, piston diameters, and cushioning configurations. The availability of multiple variants reduces spare parts inventory and simplifies maintenance procedures. For integration, the cylinder's compact design and sensor-ready feature enable seamless incorporation into existing control systems, reducing engineering effort and commissioning time.
