What Is an ISO 21287 Compact Cylinder?
An ISO 21287 cylinder is a standardized compact pneumatic actuator with reduced overall length compared to traditional ISO 15552 cylinders.
The ADN magnetic version features:
- Double acting structure
- Built-in piston magnet
- Sensor mounting slots on both sides
- Rubber buffer cushioning
- Square body aluminum profile
Compared with round body cylinders, the square body pneumatic cylinder provides:
- Better mounting rigidity
- Easier side sensor installation
- More compact machine layout
- Improved structural stability
This makes it ideal for space-restricted automation systems.

How to Select the Right Compact Pneumatic Cylinder
When choosing an ISO 21287 magnetic compact cylinder, consider:
1. Required Output Force
Force calculation:
F = P × A
Where P = working pressure
A = piston area
Ensure the cylinder provides sufficient force with a safety margin.
2. Stroke Length
Select stroke based on required movement distance plus buffer margin.
3. Installation Dimensions
Confirm mounting dimensions match ISO 21287 standard for easy replacement.
4. Environmental Conditions
For humid or corrosive environments, choose stainless steel piston rod option.

FAQ
Yes. Since it follows ISO 21287 standard mounting dimensions, it can replace equivalent compact cylinders designed under the same standard.
The integrated magnet allows non-contact position sensing through external magnetic switches. This improves automation accuracy and reduces mechanical wear.
Rubber buffer provides fixed end-stroke shock absorption and requires no adjustment. Adjustable cushion allows fine tuning but increases structure complexity and cost.
