ADN-20-20-I-P-A Festo Compact Cylinder

Model Identifier ADN-20-20-I-P-A
Official Part Number 536245
GTIN Standard 4052568087500

Technical Overview

The Festo ADN-20-20-I-P-A is a high-performance double-acting compact pneumatic cylinder designed for automated systems requiring precise linear motion in confined spaces. Conforming to the ISO 21287 standard, this actuator features a 20mm piston diameter and 20mm stroke length. It is equipped with elastic cushioning rings at both ends to minimize impact energy and a female piston-rod thread for versatile attachment. Built with high-alloy steel and anodised wrought aluminium, it offers moderate corrosion resistance and is suitable for Class 5 cleanroom environments.

Key Features

  • Double-acting mode of operation
  • Elastic cushioning rings/plates at both ends to reduce impact
  • ISO 21287 compliant design for space-saving installation
  • Position detection via proximity switch integration
  • Female thread piston-rod end

Industrial Applications

1. Cleanroom Semiconductor Wafer Clamping System

Utilizes the Festo compact cylinder to delicately hold and position semiconductor wafers during precision inspection and lithography processes within confined automated handlers.

Problem Solved

Standard pneumatic actuators generate particulate contamination and are too bulky for dense micro-assembly tools. The Class 5 ISO 14644-1 cleanroom suitability and compact ISO 21287 profile resolve strict space and purity constraints while delivering a reliable 188 N of clamping force.

2. High-Speed Packaging Conveyor Reject Mechanism

Deployed on pharmaceutical packaging lines to rapidly push defective pill bottles off the main conveyor belt immediately after failing a machine vision inspection.

Problem Solved

High-cycle rejection mechanisms often suffer from severe end-of-stroke mechanical wear and vibration. The integrated elastic cushioning rings at both ends absorb up to 0.2 J of impact energy, preventing machine damage, while the 20 mm stroke ensures quick clearance.

3. Automated End-of-Line PCB Testing Jig

Actuates physical buttons, membrane switches, and connectors on manufactured electronic devices to verify mechanical integrity and electrical continuity during automated end-of-line quality control.

Problem Solved

Testing jigs require precise linear travel, confirmation of actuation, and interchangeable tooling for different products. The M6 female thread allows for quick swapping of custom pusher tips, while the proximity switch compatibility enables closed-loop verification of the 20 mm extension.
