Key Design Features
ISO 15552 — Full Drop-In Compatibility with Festo, Camozzi, SMC
Strict ISO 15552 compliance means DNC-40×100-S is fully interchangeable with Festo DNC/DSNU, Camozzi Series 21, SMC CM2, Parker P1D and any other ISO 15552 cylinder at the same bore and stroke. No modification of existing mounting hardware is required.
Suffix “S” — Magnetic Piston for Position Sensing
The magnetic ring allows non-contact position sensing (reed, Hall effect) via sensors clipped into the T-slots of the profile body. Enables PLC integration, stroke monitoring and safety interlock logic. Recommended sensors: XC-31R (XCPC).
Aluminium Profile Body (“Mickey Mouse”)
Characteristic cross-section with continuous T-slots along the full body length allows sensor positioning anywhere along the stroke without brackets. Aluminium — lightweight, thermally conductive, corrosion-resistant.
Adjustable Pneumatic End-Position Cushioning
Built-in cushions at both end positions are adjusted via needle screws. Properly set cushioning eliminates hydraulic hammer, reduces noise and extends service life of the cylinder and attached mechanisms.
High-Quality Imported Seals
Key seal components sourced from Germany and Switzerland. Designed for dry-air operation without oil-mist lubrication. Standard Seal Kit available for in-field overhaul.
DNC Series vs SI Series — When to Choose Which
| Feature | DNC (ISO 15552) | SI (ISO 6431) |
|---|---|---|
| Standard | ISO 15552 / VDMA 24562 | ISO 6431 |
| Available bores | 32–125 mm | 32–200 mm (wider range) |
| Working pressure | up to 10 bar | up to 9 bar |
| Proof pressure | 1.5 MPa | 1.35 MPa |
| Festo/SMC compatibility | Full (ISO 15552 world standard) | Partial (ISO 6431) |
| Choose when | Standard automation, replacing Festo/SMC | Large forces (bore 160–200 mm) |
Applications for the DNC-40×100-S
Industrial automation and assembly lines — workpiece transfer, gripper actuation, mould locking. 100 mm stroke and 750 N at 6 bar — typical for machine tools and electronics assembly.
Packaging machinery — product transfer, box sealing, conveyor pushers. High cycle rates, cushioned end positions — no impact shocks.
Woodworking and furniture production — clamping devices, drilling heads, stops. Aluminium body — lightweight and corrosion-resistant in humid environments.
Food processing — dosing, sorting, container positioning. Dry-air operation — no oil contamination in the working zone.
Frequently Asked Questions about the XCPC DNC-40×100-S
What does DNC-40×100-S mean?
DNC = ISO 15552 series. 40 = bore 40 mm. 100 = stroke 100 mm. S = magnetic ring on piston for position sensors.
Is it a direct replacement for Festo or Camozzi cylinders?
Yes — full dimensional interchangeability per ISO 15552. Drop-in for Festo DNC/DSNU, Camozzi Series 21, SMC CM2 at the same bore and stroke.
What thrust force at 6 bar?
Extension force ≈ 754 N (77 kgf) at 6 bar. Formula: F = P × π × D²/4.
Can it run without air-line lubrication?
Yes. Filtered clean air, no oil mist required. Quality imported seals for long dry-air service life.
What position sensors are compatible?
XCPC XC-31R magnetic sensors — slot into T-grooves, no brackets. ISO 15552 sensors from other brands also fit.
