FIRGELLI engineering guide
Compliance language around actuators can be misleading if it is read too broadly. A component declaration does not automatically make the finished machine compliant, and an IP rating does not automatically cover every connector or installation condition.
This guide explains the actuator standards and documentation questions engineers should ask before selecting parts for a product, machine or regulated application.
Key Engineering Takeaways
- Product compliance and machine compliance are different things.
- CE, RoHS, EMC and IP ratings answer different questions.
- IP rating must match the installed environment, including cable and connector exposure.
- Medical, food, vehicle and machinery applications can add requirements beyond the actuator data sheet.
- Do not claim certification unless the document applies to the exact product and configuration.
- Use review actuator supplier questions for OEM engineers before approving an actuator supplier for production.
Engineering Guide
1. Component compliance is not system compliance
A linear actuator can be a compliant component and still be installed into a non-compliant machine. The final machine may need guarding, emergency stop behavior, wiring protection, labeling, EMC testing, risk assessment and documentation outside the actuator supplier's scope.
The clean way to handle this is to collect documents by exact actuator model and configuration, then decide which additional tests belong to the final equipment.
For OEM selection, review choose a motion control manufacturer and use the linear actuator engineering guide before treating one mark as a complete approval.
2. What common actuator compliance terms mean
CE marking generally relates to applicable European requirements for the product category. RoHS relates to restricted hazardous substances. EMC concerns electromagnetic emissions and immunity. IP rating describes ingress protection against solids and water under specific test conditions.
None of those marks tells you whether the actuator has enough force, whether the bracket is safe, whether the controller is compatible, or whether the machine risk assessment is complete.
For environmental language, start with understand linear actuator IP ratings, select IP68 waterproof actuators for washdown environments and compare washdown actuator requirements.
3. Applications that need extra review
Medical, food-processing, marine, vehicle, agricultural and public-access equipment often need more than a standard product page. Material compatibility, washdown chemicals, corrosion, noise, duty cycle, emergency release, redundant support, temperature and cleaning procedures may all matter.
If the actuator is part of a safety function, do not assume the actuator alone provides the safety rating. The control architecture, sensors, wiring, failure response and validation test all matter.
The practical review question is simple: what happens if the actuator stops, moves unexpectedly, loses position, stalls, leaks current, ingests water or cannot hold the load? Standards work should turn those failure cases into design checks, not just collect logos for a specification sheet.
Where safety behavior is part of the selection, review review safe actuator motion principles and review medical bed and table actuator considerations as starting points.
4. Actuator example: washdown packaging equipment
A washdown actuator on a packaging machine may need an IP-rated body, protected cable termination, compatible connector, stainless or corrosion-resistant exposed hardware, and a cleaning method that does not spray directly into an unprotected cable end. The actuator data sheet alone is not the whole compliance file.
The machine file should state the cleaning method, expected spray direction, cable-entry protection, inspection interval and what replacement part preserves the same environmental assumptions. Without those details, a maintenance team can accidentally defeat the original compliance work with a poor replacement connector or a rerouted cable.
Use understand corrosion-resistant actuator testing when the environment includes salt, chemicals or outdoor exposure.
Specification Checks
| Check | What it means | Engineering note |
|---|---|---|
| CE | Product conformity mark for applicable EU requirements. | Confirm the document applies to the exact product. |
| RoHS | Restricted-substance compliance. | Does not prove mechanical suitability. |
| EMC | Emissions and immunity behavior. | Final wiring and controller can change system behavior. |
| IP rating | Ingress protection against solids and water. | Installation details can reduce real-world protection. |
| Application standard | Medical, machinery, vehicle or food-equipment requirement. | Usually requires system-level review. |
Field Checklist
- Exact actuator model and configuration
- Declaration or certificate document date
- Voltage, current and wiring method
- EMC requirements for the finished system
- IP rating and installed cable/connector exposure
- Material compatibility with chemicals or salt
- Machine guarding and pinch-point review
- Emergency release or manual override needs
- Duty cycle and thermal conditions
- Documentation retained for the final equipment file
Common Mistakes
| Mistake | Why it causes problems | Better practice |
|---|---|---|
| Treating CE as a fit check | The actuator mark is used to approve force, stroke and mounting. | Do separate mechanical and electrical selection checks. |
| Ignoring configuration | A certificate for one option is assumed to cover all options. | Match documents to exact model and suffix. |
| Forgetting installed wiring | The component is sealed but the cable termination is not. | Audit the installed cable path and enclosure entry. |
Frequently Asked Questions
Does a CE-marked actuator make my machine CE compliant?
No. It may help the component file, but the finished machine still needs its own risk assessment, wiring, guarding, documentation and applicable conformity work.
Is RoHS the same as electrical safety?
No. RoHS concerns restricted substances. Electrical safety depends on voltage, current, insulation, wiring protection, controller design and the final equipment requirements.
Does an IP66 actuator work outdoors?
Often, but outdoor suitability also depends on cable routing, connector sealing, UV exposure, corrosion, temperature and whether the actuator sees pressure wash or immersion.
What does EMC mean for actuator systems?
EMC concerns electromagnetic emissions and immunity. Motor wiring, controller type, cable length, grounding and routing can affect the final system even when the actuator component is acceptable.
Do medical actuators need different review?
Yes. Medical applications may need noise, smooth motion, emergency release, cleaning, patient safety and regulatory review beyond a general actuator data sheet. Start with review medical bed and table actuator considerations for design context.
Can I rely on a product page for compliance documentation?
Use the product page for screening, but retain formal declarations, data sheets, manuals and configuration-specific documents for the project record.
Who is responsible for final machine compliance?
The party placing the final machine or product into service is normally responsible for system compliance. The actuator supplier provides component information, not a complete machine approval.
