1. Bench pickup check
Start with representative parts, including the worst expected surface condition. Check pickup contact, peel risk, air gap, and any stacked-part behavior before approving the gripper concept.

Cobot Handling Buyer Decision Framework
Treat cobot handling as a complete handling decision, not a stand-alone magnet purchase. The right choice depends on whether the workpiece can be held magnetically, whether the robot motion keeps enough margin, whether the part releases cleanly, and whether the installation scope is clear enough for quotation.
Buyer fit: For teams using cobots where compact tooling, setup speed, and payload margin are important. Before comparing price, align the practical constraints below so the quote reflects the real automation cell instead of a generic catalog condition.
| Decision Area | Buyer Question | Practical Evidence |
|---|---|---|
| Workpiece fit | Can the magnetic poles contact enough real surface area under production conditions? | Send cobot brand, model, payload at working reach, and tool flange details plus photos or drawings of the pickup face. |
| Motion margin | Will the gripper hold through acceleration, rotation, off center pickup, and stop conditions? | Review cobot payload margin because cobot payload limits leave less room for oversized tooling. |
| Release behavior | Can the part release within the placement tolerance without residual magnetism, double pickup, or stack disturbance? | Define sample acceptance criteria around cobot payload margin and record the release test result before batch release. |
| Interface scope | Are the flange, adapter, cable, connector, controller, and documentation assumptions included in the same RFQ? | Confirm cobot payload and tool center of gravity and list any custom mounting or control requirements before PO release. |
Validation Plan Before application validation
2. Robot-path check
Test the planned orientation, acceleration, tool center, cable route, and stop assumptions. A static lift is not enough when the cell includes fast motion or rotated handling.
3. Release and repeat run
Measure release timing, residual magnetism, placement tolerance, and repeatability across a small run. Use the result to freeze pole layout, interface, and quality-control notes.
Procurement Notes and Boundaries
The most common sourcing mistake is treating holding force as a fixed catalog value. In practice, payload limit is checked at the wrist but the working reach reduces the usable capacity. Verify payload capacity at the actual working reach and tool center point, not only the rated wrist payload. Another common issue is that collaborative speed limits extend the cycle time beyond the production requirement. Calculate the realistic cycle time at collaborative speed before committing to cobot-based automation for time-critical tasks.
For a quote that can move from engineering review to procurement, include the workpiece file set, automation interface, cycle target, release requirement, quantity, destination, and any custom packaging or documentation needs. If those values are not final, mark them as assumptions so the quotation can separate confirmed scope from validation-dependent scope.
- Use Contact / RFQ when drawings, photos, robot model, and quantity are ready for review.
- Review sample validation and quality control if the application includes coating, oil, burrs, stack variation, or release precision risk.
Application Evaluation Matrix
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Cobot payload margin | Reviewed with gripper, bracket, cable, and workpiece | Cobot payload limits leave less room for oversized tooling. |
RFQ Preparation Checklist
- Cobot brand, model, payload at working reach, and tool flange details
- Workpiece material, weight, and pickup face (flat, curved, or irregular)
- Cell layout: operator zone, guarding strategy, and speed-limit assumptions
- Setup frequency: single-product vs. multi-product changeover needs
- Quantity, project phase, and whether teach-pendant programming support is needed
Risk and Mitigation
- Payload limit is checked at the wrist but the working reach reduces the usable capacity.: Verify payload capacity at the actual working reach and tool center point, not only the rated wrist payload.
- Collaborative speed limits extend the cycle time beyond the production requirement.: Calculate the realistic cycle time at collaborative speed before committing to cobot-based automation for time-critical tasks.
- Operator assumes the cobot cell is safe without a formal risk assessment.: Conduct a risk assessment per ISO 10218-2 and ISO/TS 15066 covering the gripper, workpiece, motion, and magnetic field exposure.

Buyer FAQ
Is cobot handling slower than industrial robot handling?
Cobots in collaborative mode run at reduced speed and force. For light parts and short transfers, the difference may be small. For heavy or high-speed tasks, an industrial robot may be more suitable.
Can the same magnetic gripper move between different cobots?
The magnetic module can be reused if the adapter plate matches the new cobot flange and the payload capacity is sufficient. Adapter plates are usually cobot-model-specific.
Do I need safety fencing with a cobot magnetic gripper?
It depends on the risk assessment. Cobots allow reduced guarding in some configurations, but the gripper edges, workpiece, and magnetic field must be evaluated for operator contact risk.
