Omron Y92B-A100 Heat Sink

The Omron Y92B-A100 is an aluminium heat sink designed for screw mounting onto solid-state relays. It provides a thermal resistance of 1.63 °C/W and includes a fan connection for active cooling. The unit measures 4.02 in deep, 3.94 in wide and 1.79 in high with a single mounting hole. Its transparent finish suits industrial control panels where relay thermal management is required.

Thermals, noise and power

The 1.63 °C/W rating defines the passive dissipation capability before airflow is added. When a fan is attached to the provided connection, forced convection lowers the effective resistance further, though the exact delta depends on the fan selected. The heat sink itself adds no acoustic signature; any noise comes solely from the external fan. No electrical power is drawn by the heat sink, so it does not increase the enclosure's power budget.

Upgrade context

This component replaces a smaller or lower-efficiency heat sink when a solid-state relay runs hotter than its derating curve allows. The jump is worth it if the existing thermal path cannot keep the relay base temperature within specification under continuous load. It is not suited for applications that demand a mounting pattern with multiple holes or a thermal resistance below 1.63 °C/W without forced air.

Questions about this item

How do I install the Omron Y92B-A100 heat sink with its screw mounting and single hole?

Align the single mounting hole with the solid-state relay base, insert the screw through the aluminium fin stack and tighten evenly; the fan connection point faces outward for airflow.

What maintenance will this aluminium heat sink need over time?

Periodically remove dust from the fins with compressed air and verify the screw remains tight; the fan connection should be checked for secure seating.

At what thermal load does the 1.63 °C/W resistance become the limiting factor?

Sustained power that raises the relay junction above its rated maximum will hit the 1.63 °C/W limit first; ensure airflow matches the dissipation required.
