Stainless steel construction provides high corrosion and acid resistance, extending service life in washdown environments and reducing replacement costs in food and pharmaceutical lines. This translates to lower maintenance intervals and higher equipment availability for production lines that require frequent cleaning. ISO 6432 compatibility with a 20 mm bore and 40 mm stroke standardizes mounting and simplifies component sourcing, enabling faster installation and scalability across multiple machine decks and line configurations. The magnetic piston is included as standard, enabling straightforward integration with reed switches and sensor packages (example: M/50 LSU) for reliable end-of-stroke sensing and improved process control. Buffer cushioning minimizes impact loads, supporting longer life in high-speed applications and reducing vibration-induced wear during rapid cycling. Operating from -10 to 80 °C and 1 to 10 bar, it performs consistently in varied environments, including near-ambient temperatures and process lines with variable pressure. Comprehensive mounting options (rear hinge KQM/8020/24, foot M/P72404, piston rod clevis KQM/8020/25) and switch kits (QM/33/020/22) enable flexible installation. The 20 mm bore, G1/8 port, and Pneufit 10 fittings compatibility further streamline assembly, cutting setup time and part complexity for OEMs.

FAQs
KM/8020/M/40 supports rear hinge mounting (KQM/8020/24), foot mounting (M/P72404), and piston rod clevis mounting (KQM/8020/25). This range enables rapid alignment with existing frames and tooling, reduces need for custom brackets, and speeds setup. For integrated sensing, compatible switch brackets (QM/33/020/22) and reed switch options (M/50/LSU/5V) simplify wiring and commissioning.
Key specs include a 20 mm bore, 40 mm stroke, G1/8 port, 1–10 bar operating pressure, and -10 to 80 °C operating range. The magnetic piston supports reliable sensing, while buffer cushioning reduces impact, which together translate to lower wear per cycle and extended life in high-cycle environments such as conveyors and pick-and-place stations.
Yes. The cylinder features high corrosion resistance with stainless steel barrel and piston rod materials, enabling washdown compatibility and compliance with hygienic standards. Its ISO 6432 mounting and magnetic piston support integration with sensor systems used in food processing and packaging lines, ensuring cleanability and reliability in sanitary environments.
The cylinder conforms to ISO 6432 mounting standards and uses a magnetic piston as standard, with a design suitable for food industry applications. Materials specification (AISI stainless grades 304/303 equivalents) supports corrosion resistance requirements typical in sanitary and chemical-exposure environments.
Benefits include reduced maintenance due to corrosion resistance and buffer cushioning that minimizes mechanical wear, leading to longer service intervals and higher up-time. The standardized mounting, fittings compatibility (Pneufit 10), and available switch options streamline installation and future upgrades, delivering lower total cost of ownership over the actuator’s lifecycle.
