Mounting
Sabertooth 2x32 has four mounting holes, which are sized for 4-40 machine screws. 5/8” Phillips
machine screws are provided, but other lengths can be used as well. Sabertooth 2x32 has a single-piece
machined heat sink. The heat sink features a pin-fin design, so it can be mounted in any orientation with
acceptable thermal performance.
The heat sink is not electrically connected to the electronics of the Sabertooth 2x32. If there is a metal
chassis available the best thermal performance will come from mounting the flat bottom of the heat
sink directly to the chassis as shown in the photograph above. If the driver is mounted to an insulating
material such as wood or plastic, it may be better to use standoffs to allow better cooling.
Because Sabertooth 3x32 is a high power component, capable of supplying up to two kilowatts of
continuous output power, it will get warm in use. If there is airflow available in the design, having the
Sabertooth 2x32 in that airflow will lead to lower board temperatures. At a very minimum, allow some
space for air movement between the edges of the heat sink and the enclosure.
There is a printable full size mounting diagram at the end of this manual which can be used to mark the
location of the mounting holes. There are also CAD models of the Sabertooth 3x32 available for
download on Dimension Engineering’s website.
