SMC recently expanded its product portfolio to address modern factory automation challenges regarding space and installation efficiency. The company introduced smaller bore sizes for its MGPK guided cylinders and upgraded the PFUW flow sensor series. These updates target engineers who need high-performance components that fit within increasingly cramped machine footprints. Consequently, these innovations help manufacturers streamline their assembly lines while maintaining high operational reliability.
Engineering Slimmer Solutions with MGPK Guided Cylinders
The redesigned MGPK series achieves a significant reduction in both physical volume and overall weight. Specifically, the new design cuts volume by 28 percent and reduces weight by up to 41 percent. Moreover, SMC added ultra-compact bore sizes of 6mm, 8mm, and 10mm to the lineup. These small cylinders effectively function as mechanical stoppers, which simplifies the overall machine design. As a result, engineers can eliminate redundant components in tight automation cells.
Maximizing Durability and Simplified Commissioning
Despite the smaller size, the MGPK cylinders offer 33 percent thicker plates to ensure structural rigidity. SMC also integrated a lube retainer on the guide rod to extend maintenance intervals for high-cycle applications. In addition, the symmetrical port positioning makes the piping process much more straightforward. For larger models, an optional air cushion helps dampen end-of-stroke impacts and reduces mechanical wear. Therefore, these features collectively accelerate the commissioning process on the shop floor.
Non-Intrusive Monitoring with PFUW Flow Sensors
The updated PFUW series clamp-on flow sensors now support measurement ranges up to 200 L/min. Because these sensors mount to the exterior of the pipe, technicians do not need to cut lines. This non-intrusive method eliminates common risks such as fluid contamination or potential leak points. Furthermore, the “eight zeros” philosophy addresses concerns like pressure loss and wetted-material compatibility. This makes the PFUW series ideal for high-purity environments or chemical processing applications.
Seamless Integration through IO-Link Technology
Modern control systems require real-time data, and the PFUW series delivers this through full IO-Link compatibility. The sensors work with various pipe materials, including both metal and hard resins. Users can choose from three nominal port sizes to fit 1/2-inch, 3/4-inch, or 1-inch piping. Additionally, the ability to detect flow down to zero supports precise monitoring during system startups. This level of connectivity ensures that flow data integrates directly into the broader PLC or DCS architecture.
Author Insight: Why Compact and Clamp-On Designs Matter
In my experience, the trend toward “micro-automation” is forcing a total rethink of component selection. SMC’s decision to reduce cylinder weight while increasing plate thickness is a clever engineering trade-off. It provides the durability of heavy-duty components without the bulky footprint. Similarly, clamp-on sensors represent a major win for maintenance teams. Traditional flow meters often require system shutdowns for installation, but these sensors allow for “hot” retrofits without interrupting production.
Practical Application Scenarios
- Electronics Assembly:Â Use the MGPK 6mm bore cylinders as precision stoppers on high-speed conveyor belts.
- Chemical Dosing:Â Deploy PFUW sensors to monitor corrosive fluids without risking sensor corrosion or fluid leaks.
- Food & Beverage:Â Retrofit existing stainless steel lines with clamp-on sensors to maintain strict hygiene standards.
- Robotic End-Effectors:Â Leverage the weight-reduced MGPK cylinders to improve the dynamic response of robotic arms.
