The 12 mm bore with a 40 mm stroke creates a compact pneumatic cylinder footprint that frees valuable machine space while preserving precise actuation in confined areas. This space-saving profile directly reduces enclosure size and enables higher equipment density on automation lines, improving overall line throughput. The double-acting design delivers controlled push and pull motions, with a theoretical 68 N force that supports reliable clamping, positioning, and transfer tasks without oversizing the actuator. A magnetic piston enables straightforward, non-contact position sensing integration with PLCs and sensors, simplifying control schemes and feedback reliability in industrial environments. The anodised aluminium barrel and stainless steel piston rod provide excellent corrosion resistance and long life seals, enhancing durability in wash-down or humid settings and reducing maintenance cycles. The M5 port size, combined with a 1–10 bar operating range and -5 to 80 °C capability, ensures compatibility with standard valve manifolds and common compressed-air systems, easing installation and start-up. Note that there is no internal cushioning, so for soft-stop needs, external dampers or strategic mounting should be employed to control impact and wear. Overall, this RM/92012/M/40 model aligns with compact pneumatic cylinder solutions designed for high-density layouts, quick changeovers, and dependable repeatability across demanding manufacturing environments.

FAQs
To install RM/92012/M/40 on a standard M5 port manifold, ensure the cylinder is oriented for optimal stroke alignment and secure the mounting with appropriate bolts. Connect the M5 port fittings to the manifold using compatible quick-connect or threaded air fittings, verify air supply is within 1–10 bar, and confirm the magnetic piston position is compatible with any non-contact sensors. Seal and test for leaks before cycling at operating pressure. Proper mounting minimizes side loading and extends seal life, while the compact form factor simplifies integration with common automation busses and control electronics.
The 12 mm bore and 40 mm stroke deliver a compact footprint that fits on tight pick-and-place stations while providing reliable linear actuation. The double-acting configuration supports push and pull movements with predictable force, reducing cycle times and improving placement accuracy. A magnetic piston facilitates sensor-based position feedback, enabling straightforward integration with PLCs and inline quality checks, which is essential for high-mrequency packaging and assembly lines.
Yes, RM/92012/M/40 is designed for a 1–10 bar operating range (14–145 psi). Its theoretical force is 68 N, enabling reliable actuation for standard automation tasks such as clamping, indexing, and light material handling. When operating near the limits of this range, ensure the preload and mechanical load are compatible with the stroke and speed requirements to maintain consistent performance and avoid premature wear.
RM/92012/M/40 supports frequent cycling typical of compact automation tasks, but it has no internal cushioning. For high-speed or high-impact applications, plan for external damping or soft-stop strategies at the end-of-stroke to reduce wear and noise. The magnetic piston aids in sensing feedback for precise stop points, helping to optimize cycle timing. If cushioning is essential, select compatible external dampers or mechanical landings that align with the cylinder’s mounting and stroke length.
Extend life by maintaining clean, dry compressed air within the 1–10 bar range, inspecting seals for signs of wear, and verifying fastener integrity during routine checks. Regularly inspect the stainless steel rod and anodised aluminium barrel for corrosion or scoring, and ensure the magnetic piston and sensing setup remains unobstructed. Avoid misalignment and side loading, replace worn components in the fleet in a timely manner, and follow manufacturer lubrication recommendations to minimize friction and maximize cycle life.
