Sensata / Crydom DIN Rail Relay Heatsink HS501DR with +5°C/W Thermal Resistance, 54g Weight

The Sensata / Crydom HS501DR DIN Rail Relay Heatsink is engineered to protect solid-state relays from thermal damage caused by heat buildup during normal operation. Featuring steel construction with a yellow zinc plating, it offers excellent resistance to impact and corrosion, enhancing durability and longevity.

Weighing only 54 grams, this heatsink places minimal mechanical load on the mounted equipment, facilitating reliable and stable installations on DIN rails. The vertical fin design maximizes surface area, improving heat transfer away from the relay and promoting efficient airflow.

With a thermal resistance of +5°C/W, the HS501DR provides effective temperature control, ensuring the relay operates within safe thermal limits. For enhanced cooling, it is recommended to combine this heatsink with forced airflow via a small fan and maintain at least one inch of clear space below to allow proper air circulation.

This relay heatsink is commonly employed in various industrial and commercial applications including I/O subsystems, automation systems, and medical equipment, where maintaining optimal operating temperatures is critical for system reliability.

Designed for DIN rail mounting for easy installation. Constructed from steel with yellow zinc plating for strong corrosion resistance. Lightweight at 54 grams to minimize strain on equipment. Features vertical fins for enhanced heat dissipation and airflow.

Offers a thermal resistance of +5°C/W for optimal heat management. Suitable for use in I/O subsystems and medical equipment applications. Best performance achieved with forced airflow and minimum one-inch clearance below the heatsink.
