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

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

The Festo ADN-16-20-A-P-A is a compact double-acting pneumatic cylinder from the ADN series, conforming to ISO 21287 — the international standard for compact cylinders. With a 16 mm bore diameter and a 20 mm stroke, this unit is engineered for installations where space is limited but reliable force output is non-negotiable. The ADN series is Festo's answer to tight-envelope automation: shorter overall length than standard ISO cylinders, versatile mounting options, and cleanroom suitability up to ISO Class 5 make it a go-to choice across a wide range of industries.

Key Features

• ISO 21287 Compliant — Interchangeable with other manufacturers' compact cylinders of the same bore and stroke; simplifies replacement and standardisation on your production line.
• Double-Acting Operation — Powered stroke in both directions ensures positive control of advance and return, with 121 N advance force and 90 N return force at 6 bar.
• Elastic Cushioning at Both Ends — Absorbs end-of-stroke impact energy (rated at 0.15 J), reducing mechanical shock and extending service life in high-cycle applications.
• Proximity Switch Ready — The cylinder body is profiled for standard Festo proximity switches, enabling position feedback without additional mounting brackets in most cases.
• M5 Pneumatic Connection — Compact port size consistent with the cylinder's small footprint; compatible with Festo QS-M5 and NPQM push-in fittings.
• M6 Male Piston Rod Thread — Standard metric thread for direct connection to clevis pins, rod clevises, or custom tooling without adapters.
• Wide Operating Pressure Range (1–10 bar) — Operates across standard industrial compressed air supply pressures without special regulation in most plant environments.
• Cleanroom Class 5 per ISO 14644-1 — Suitable for environments where airborne particulate levels are controlled; relevant for pharmaceutical, electronics, and food-grade automation.
• LABS/PWIS Conformity (VDMA 24364-B1/B2-L) — Paint-wetting impairment substance free; critical for automotive body shop and surface coating applications.
• Wide Ambient Temperature Range (−20 °C to +80 °C) — Operates reliably in both cold storage environments and high-temperature industrial zones.
