The stainless steel body delivers outstanding corrosion resistance in washdown environments, extending service life and reducing replacement intervals for food processing lines. The 25 mm bore and 40 mm stroke provide a compact yet capable actuator for small to mid-range linear tasks, enabling reliable cycle times and repeatable positioning. The magnetic piston is standard, enabling straightforward sensing with compatible reed switches and control electronics. When paired with the M/50 magnetically operated reed switch (5 m cable), integration into existing automation networks is simplified, reducing wiring and installation risk. ISO 6432 compliance guarantees interchangeability with common mounting patterns, while the G1/8 port and 1–10 bar operating range fit standard pneumatic supplies. Adjustable cushioning minimizes impact energy, protecting both the actuator and the driven load and extending life. With multiple mounting and fitting options including foot mounting, rear hinge mounting, and piston rod clevis mounting, plus Pneufit 10 push-in fittings for fast, leak-free connections, installation is faster and less error-prone. Theoretical force of 294 N provides a reliable balance of performance and efficiency for numerous tasks across packaging and material handling. Designed for food industry applications, the combination of German engineering and stainless materials supports compliance and audit readiness, while a compact footprint and magnetic switching capability enable scalable lines and easier maintenance planning.

FAQs
KM/8026/M/40 supports multiple mounting configurations to simplify installation and alignment. Foot mounting style C provides a robust base, while rear hinge mounting (KQM/8020/24) offers flexible positioning. Piston rod clevis mounting (KQM/55433/25) enables easy linkage to actuated components. These options help optimize stroke reach, load alignment, and maintenance access on packaging lines.
The standard is a magnetic piston with optional reed switch compatibility. The M/50 magnetically operated reed switch (5V) is available for inline sensing, and QM/33/025/22 switch mounting brackets simplify mounting. This combination supports reliable position feedback, simplifies control integration, and reduces wiring complexity in automated lines.
Yes. The cylinder uses a stainless steel 1.4301 (AISI 304) barrel and 1.4305 (AISI 303) piston rod, delivering high corrosion resistance ideal for washdown and hygienic environments. Operating temperature ranges from -10 to 80 °C and it is designed for compressed air duty with adjustable cushioning, making it well-suited to food processing and packaging applications.
Key specs include a 25 mm bore and 40 mm stroke, double-acting operation, G1/8 port size, and a working pressure range of 1 to 10 bar. The theoretical force is 294 N, and the standard is ISO 6432. The unit features adjustable cushioning for controlled deceleration and a magnetic piston for easy sensing.
The stainless steel construction offers superior corrosion resistance, reducing part replacements in harsh environments. Adjustable cushioning minimizes impact wear on both the actuator and load, extending service life. Standard magnetic sensing enables easy integration with existing control systems, while common mounting and Pneufit 10 fittings speed up installation and troubleshooting, lowering downtime and total cost of ownership.
