Industrial / Heat Sinks
SRQ-XJ-43
The SRQ-XJ-43 heat sink is designed for through-panel or chassis-mount installations, allowing heat to be conducted away from enclosed enclosures. The precision-machined mounting surface ensures consistent thermal contact with device packages. Suited for outdoor industrial controllers, sealed drive units, and ruggedized power electronics.
Key Features
- Designed for through-panel and chassis-mount installation configurations
- Conducts heat away from internal electronics to external enclosure surfaces
- Eliminates need for internal airflow by transferring heat through the panel
- Sealed enclosure compatible design prevents ingress of dust and contaminants
- Mounting flange ensures secure mechanical attachment to panel cutouts

Frequently Asked Questions
How does through-panel mounting improve thermal management in sealed enclosures?
Through-panel mounting allows the heat sink to protrude through the enclosure wall, exposing the fin array to ambient air outside while keeping internal electronics sealed. This eliminates the need for ventilation openings or internal fans, maintaining IP54 or higher ingress protection ratings while still dissipating heat effectively.
What sealing provisions does the SRQ-XJ-43 include for panel installations?
The SRQ-XJ-43 includes a mounting flange designed to accept a gasket or sealant between the heat sink body and the panel surface. This maintains the enclosure's IP rating at the panel penetration point. Gasket material selection should match the environmental requirements of the installation.
Is the SRQ-XJ-43 suitable for outdoor installations?
Yes. The anodized aluminum construction resists corrosion from moisture and UV exposure, making it suitable for outdoor enclosures. The through-panel design keeps the fin array exposed to natural convection outside while protecting internal components from environmental ingress.
