Festo ADN-16-20-I-P-A – Compact ISO Cylinder | Bore 16mm, Stroke 20mm | Murali Pneumatics Coimbatore

Festo ADN-16-20-I-P-A – ISO 21287 Compact Cylinder Overview

The Festo ADN-16-20-I-P-A is a space-saving, double-acting pneumatic cylinder from the ADN series, designed and manufactured in compliance with ISO 21287 — the international standard for compact pneumatic cylinders. With a 16mm piston diameter and a 20mm stroke, this cylinder is engineered for applications where installation envelope is tight but performance and reliability cannot be compromised. The ADN series is well regarded in automation engineering for its clean profile, versatile mounting options, and compatibility with the full Festo accessory ecosystem.

Key Features

• ISO 21287 Compliant Design — Ensures dimensional interchangeability with other ISO-standard compact cylinders; simplifies retrofitting and sourcing.
• Double-Acting Operation — Powered stroke in both directions provides precise, controlled motion in both advance and return — ideal for gripping, clamping, and positioning tasks.
• Female Thread Piston Rod End (M4) — Allows direct coupling of grippers, tooling, or end effectors without additional adapters, saving assembly time.
• Proximity Switch Ready (Position Detection) — Integrated T-slot groove on the barrel accepts Festo SME/SMT/SIES series proximity switches; no separate bracket required for sensor mounting.
• Elastic Cushioning at Both Ends — Built-in rubber cushioning rings absorb end-position impact energy (rated 0.15 J), reducing noise, vibration, and mechanical wear at stroke limits.
• Cleanroom Class 5 Suitability (ISO 14644-1) — Tested and certified for cleanroom use; suitable for pharmaceutical, food processing, and electronics assembly environments.
• LABS/PWIS Conformity (VDMA 24364-B1/B2-L) — Paint-wetting impairment substance free; safe for use in automotive painting lines and surface-critical environments.
• High-Alloy Steel Piston Rod — Corrosion-resistant and hardened for extended service life even under lateral load or in moderately corrosive environments (CRC 2).
• Anodised Aluminium Barrel and Cover — Smooth anodising on the barrel reduces friction and wear on seals; the cover uses wrought aluminium alloy for structural rigidity.
• Multiple Mounting Options — Supports through-hole mounting, female thread mounting, and accessory-based mounting; any mounting position is permissible.
