6.4.2 Heat Release Effect by Heat Sink Application
The graph below shows the temperature rise (maximum value) from the ambient temperature when
the unit is operated with 50% duty with 2 types of heat sinks applied on the attachment surface (top
surface).

Note : Even if a heat sink is attached on the top of the unit, the temperature on the fingers
would not decrease much. To block heat from being conducted to the work part, use a
material with low heat conductivity such as polyacetal for the finger attachments. The
heat of the unit is conducted from the fingers to the work part via the finger
attachments.
