How Magswitch industrial magnets unlock speed, flexibility, and precision in collaborative robot workflows.
Collaborative robots (cobots) have quickly become a crucial tool for metal fabricators and welding shops looking to automate repetitive, labor-intensive, or ergonomically dangerous tasks. With their small footprint, ease of programming, and ability to safely work alongside humans, cobots excel in high-mix, low-volume environments, exactly where traditional automation struggles.
Yet, the success of a cobot often depends on its end-of-arm tooling (EOAT). In ferrous metal manufacturing, magnetic grippers have emerged as the most efficient, reliable, and flexible EOAT technology available. This is exactly where Magswitch delivers unmatched performance.
The Advantage of Industrial Magnets in Cobot Automation
Traditional cobot grippers, vacuum cups, and mechanical clamps have clear limitations:
- Vacuum struggles with oily, perforated, or textured materials
- Mechanical clamps require access around individual parts for the clamp arm or gripper fingers
- Changeover time slows productivity
- Wear parts increase maintenance
Magswitch magnetic grippers eliminate these issues through:
- Instant hold and release with no air lines or vacuum systems
- Strong grip on smooth, irregular, hot, oily, or perforated steel
- No deformation of thin-gauge sheet metal
- Consistent performance across part variations
- Option for all-electric actuation
The result is faster, cleaner automation, no leaks, no suction failures, no pinch points.
The Magswitch Difference: Variable-Flux Magnetic Technology and Integrated Part Present Sensing
Many magnets are always on or difficult to control. Magswitch’s patented Variable-Flux™ technology allows precise switching, holding, and release through a simple electrical signal. Most magnets also require the use of an external part present sensing. Magswitch integrates sensing into the magnet to check for the proper part present.
Key advantages of Magswitch magnetic technology:
- Zero residual magnetism, parts release cleanly
- Low power consumption, energy is used only during switching
- Lightweight bodies optimized for cobot payload limits
- Repeatable grip force for reliable pick consistency
- Enhanced safety with predictable hold characteristics
- Part Detection with proper part present sensing eliminates double picks
This makes Magswitch tools ideal for UR, FANUC CRX, ABB GoFa, Doosan, Omron, and other robotic platforms.

These tools allow shops to rapidly adjust to new jobs, critical for flexible automation.
Cobot Applications Transformed by Magswitch Magnets
Sheet Metal Pick-and-Place
Magnets grip securely even on:
- oily steel
- perforated sheets
- textured surfaces
- thin-gauge material that vacuum can’t seal on
This reduces mis-picks and increases cycle-time consistency.
Part Presentation to Robotic Welders
Cobots require predictable, repeatable placement. Magswitch tools ensure parts stay aligned, even when tack welds introduce stress or heat distortion.
Material Staging & Kitting
Magnets simplify moving:
- nested laser-cut parts
- blanks and formed components
- work-in-process assemblies
This reduces ergonomic strain and speeds downstream operations.
Bin Picking & Nested Sheet Separation
Variable-flux magnets can isolate the top sheet of a stack, solve nested-part challenges, and handle mixed metal thicknesses while detecting proper part presence.
Automated Fixturing for Welding
With Magswitch fixturing tools, cobots can repeatably position workpieces or assist human welders by stabilizing components during assembly.
A Typical Cobot Workflow Enhanced by Magswitch
Imagine a UR10 cobot feeding a welding robot in a fabrication cell. The UR10 is mounted on a worktable with a Magbase 10 2.0:
- Pick: A Magswitch Cobot E30 lifts a laser-cut part from a stack, even with oil or surface scale.
- Detect: Integrated part present sensing in the Cobot E30 detects the proper part was picked.
- Place: The cobot consistently positions the part in a fixture.
- Present: The welding robot performs its weld sequence with minimal repositioning.
- Unload: The cobot returns finished parts to a pallet or staging area.
Measured results observed in similar setups:
- Up to 40% faster cycle times
- Major reductions in mis-picks compared to vacuum grippers
- Lower operating costs due to reduced wear and air consumption
- Increased consistency across all part types
Choosing the Right Magswitch Tool for Your Cobot
When selecting a magnetic gripper, evaluate:
- Material thickness & composition
- Part size, shape, and weight
- Cobot payload capabilities
- Cycle time requirements
- Fixturing or presentation needs
Magswitch engineering can assist with load charts, force curves, and application analysis.
Integrating Magswitch with Your Automation Platform
Magswitch tools integrate easily using:
- Direct robot interface or Ethernet IP
- Modular mounting brackets
- Robot-brand-specific accessory plates
- Standard M8/M12 industrial connectors
Most cobots can control Magswitch tools in minutes.
