Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the response time of the system? **A**: The response time from sensor input to damper adjustment is typically 10–20 ms, as listed in the directory reference. This value should be confirmed with the manufacturer for the specific model. ### Q: What is the operating temperature range? **A**: The system is designed to operate from -40°C to 85°C, with full performance from -30°C to 70°C, per ISO 16750-4. Verify these limits with the supplier for your application. ### Q: What is the ingress protection rating? **A**: The system is rated IP67 per IEC 60529, meaning it is dust-tight and protected against temporary immersion. This rating should be verified for the actual product. ### Q: What standards apply to the damping force tolerance? **A**: The damping force tolerance is ±5% at 0.5 m/s piston velocity, per ISO 8608. This is a reference value; confirm with the manufacturer for the specific model. ## 6.
