Environmental and compliance considerations for onboard equipment
Reliable onboard equipment depends on the combined fit of power, vibration, temperature, EMC, protection and installation conditions—not a single specification.
Power and transient protection
Confirm the actual vehicle power range, starting and transient conditions, protective measures and grounding requirements before selecting connected equipment.
Vibration, temperature and mounting
Long-term vibration, shock, temperature variation and cooling conditions affect equipment, storage, connectors and fixing structures. Confirm mounting, cooling, strain relief and service access.
EMC and cable routing
Power-signal separation, shielding, grounding, locked connectors and suitable routing help reduce image interference, communication instability and maintenance issues.
Standards must be checked against the project
EN 50155, IEC 61373 and EN 50121 are commonly used reference points for onboard equipment. Applicable versions and acceptance boundaries must be confirmed against the vehicle and project specification.
Frequently Asked Questions
Does one test report make a product suitable for every project?
No. Configuration, mounting position, power, interfaces, vehicle environment and the applicable specification must still be checked.
Why include cables and connectors in environmental review?
They experience vibration, flexing, temperature, oil and EMI and directly affect video, network and power reliability.
