FAQs
Plan for a solid, level mounting surface and align the rod axis to avoid side loads. Use M5 ports with appropriate fittings and ensure clean, dry compressed air within 1–10 bar. The unit has no internal cushioning, so consider external shock absorption or end-of-stroke stops to protect actuating components and sensors.
The magnetic piston provides reliable position feedback compatible with magnetic or magnetic-inductive sensors, enabling straightforward integration with PLCs and safety controllers. This supports accurate end-of-stroke detection, easier commissioning, and robust performance in automation lines with frequent cycling.
Yes. The low-friction, long-life seal design reduces wear and maintenance intervals, while the 20 mm bore and 55 mm stroke support fast, repeatable actuation. Combined with corrosion-resistant materials, it delivers consistent performance in demanding applications and helps achieve higher overall equipment effectiveness.
Operating pressure is 1–10 bar (14–145 psi) and operating temperature ranges from -5 to 80 °C (23 to 176 °F). Ensure air supply is dry and filtered to maximize seal life, and avoid pressures or temperatures outside these limits to maintain performance.
