Frequently Asked Questions
How does the SRQ-XJ-30 handle vibration in industrial machinery applications?
The SRQ-XJ-30 is manufactured from a single extruded aluminum profile, eliminating joints or bonded fins that could loosen under vibration. When properly fastened using the provided mounting points, it maintains reliable thermal contact with the device under typical industrial vibration profiles.
What is the expected service life of the SRQ-XJ-30 in continuous operation?
As a fully passive component with no moving parts, the SRQ-XJ-30 has an indefinite mechanical service life under normal operating conditions. Thermal performance remains stable as long as the mounting interface is maintained and the fin channels are kept free of dust accumulation.
Is the SRQ-XJ-30 suitable for outdoor or protected outdoor enclosures?
The SRQ-XJ-30 is designed for indoor and protected outdoor use. Its anodized finish provides adequate corrosion resistance for IP54-class enclosures. For fully exposed outdoor deployments, additional protective coatings or sealed enclosure mounting is recommended.
