Feature → Business Impact → Application: The 40 mm diameter with a 25 mm stroke delivers a clearly reduced footprint, enabling installation in tight machine envelopes and high-density layouts. This directly lowers panel thickness and mounting hardware requirements while maintaining reliable stroke performance for pick-and-place and clamping routines in automated lines. Application: small-footprint robotics, packaging machines, and line-side actuators. The piston rod is stainless steel and the barrel is an anodised aluminium alloy, delivering corrosion resistance and durability in demanding environments, which reduces unplanned downtime and extends service intervals. Business impact: lower maintenance costs and improved uptime in continuous-cycle operations. Feature → Magnetic piston enables end-of-stroke sensing and straightforward integration with existing sensors and PLCs, reducing wiring complexity and enabling precise position feedback in automation tasks. Application: sensorized actuation in automated assembly and material handling. Feature → Low-friction, long-life seal design minimizes wear and leakage, promoting longer service life and predictable performance. Application: high-cycle punching, aligning, or clamping operations where reliability matters. Feature → ISO/VDMA compatibility with a compact form factor reduces rework and enables quick mounting in legacy systems. Application: retrofits and upgrades in established pneumatic lines. Feature → Operating range of -5 to 80 °C and 2 to 10 bar supports diverse process conditions, ensuring consistent actuation across varying production environments. Application: general-purpose automation across manufacturing cells.

FAQs
The RM/91040/N2/25 uses a standard G1/8 port and is designed for compatibility with common mounting patterns found in ISO/VDMA-style pneumatic systems. This simplifies retrofits and enables straightforward installation into existing pneumatic circuits without custom adapters, reducing lead times and installation costs.
This model operates from -5 to 80 °C and supports 2 to 10 bar nominal operating pressure. These ranges cover a wide range of manufacturing environments, from dry packaging lines to humid processing cells, ensuring consistent actuation and reduced risk of binding or seizing in varied conditions.
The RM/91040/N2/25 is a single-acting cylinder. This configuration provides efficient linear actuation in one direction with a return mechanism typically achieved through external springs or gravity, simplifying control logic and reducing cycle complexity in repetitive tasks.
The barrel uses an anodised aluminium alloy and the piston rod is stainless steel (austenitic). This combination offers strong corrosion resistance and durability in challenging environments, extending service life and reducing maintenance in washdown or humid applications.
Ideal for space-constrained automation tasks such as pick-and-place, clamping, positioning, and sensor-assisted actuation in compact packaging lines or machine tending. The magnetic piston supports straightforward end-of-stroke sensing, enabling reliable integration with PLCs and sensors for precise control in automation workflows.
