Double the Speed, 90% Less Energy: The Future of Ejection

Why Automated Inspection is Moving Beyond 1950s Technology

 
The manufacturing landscape is reaching a significant tipping point. From bottled beverages and cans to delicate confectioneries and agricultural produce, pneumatic cylinders have been the go-to solution for ejecting defective goods during automated inspection (vision, x-ray, weight, etc.). Yet, as the industry pushes for higher line speeds and smaller energy footprints, the limitations of these air-based systems are becoming increasingly clear.
Recently, three of the world’s leading Vision Inspection OEMs signaled a major shift in the industry by transitioning their entire product lines from pneumatic cylinders to SMAC servo electric actuators. This move highlights a growing trend: the pursuit of faster machines, extended equipment life, and significantly lower operating costs.
 

The Performance Shift: Why Now?

The transition to electric moving coil technology isn't just about modernization—it is about achieving measurable gains that directly impact a facility's bottom line. For engineers and plant managers, the benefits of this shift include:
 

• Precision at Speed: SMAC actuators operate up to 2x faster than traditional air cylinders. With a motion repeatability of ±1 msec (compared to the ±15 msec typical of air), machines can run at higher velocities without sacrificing accuracy or reliability.

• Operational Longevity: Moving coil technology offers a 10x longer cycle life, drastically reducing the frequency of maintenance shutdowns and part replacements.

• Sustainability & Efficiency: In an era of rising energy costs, these actuators consume up to 90% less energy than pneumatic systems, which often suffer from leaks and inefficient compressors.

• Simplified Inventory: Because SMAC actuators are programmable in position, velocity, and force modes, a single unit can often replace 10 to 15 different air cylinder models, streamlining spare parts management.

Engineering for Simplicity

One of the primary hurdles to "going electric" has traditionally been complexity. SMAC has addressed this by integrating the controller directly into the actuator. This makes the unit as easy to operate as a standard air valve and cylinder, allowing for a seamless replacement process in high-speed ejecting and positioning applications.
For specialized environments, such as food and beverage or liquid handling, IP-rated options are available to ensure that high performance is matched by high durability.
 

Looking Ahead

We are currently looking for distributor partners who want to help OEMs bridge the gap between "how it’s always been done" and the high-speed, reliable future of linear servo technology.
