Fundamentals of the Camera’s Heat Dissipation
The power consumption of the D400e cameras is the main determining factor for heat creation
inside the camera, which depends on the operation mode of the camera. In the case that all
available functionality of the camera (i.e. frame rates or projector intensity) is used at maximum
capacity, the power consumption and thus the heat generation increases accordingly. Aside from
the resource utilization of the camera, the power supply option also has a large effect on power
consumption. PoE (power over Ethernet) has a higher power consumption due to the uneven
efficiency of circuitry compared to the circuitry used when powering the camera via the M8
connector.

Table 16 – D400e Maximum Power Consumption
Most of the power consumed by the camera is converted to heat and consequently, the camera
will generate heat that is released to the ambient via the camera’s housing.
Due to the internal structure of the camera, most heat dissipation will happen via the back side.
Therefore, this part of the camera body is intended for thermal coupling with an external dissipative
element such as a camera holder or stand. In tabletop applications, a simple heatsink element can
be used. It is recommended to use metal parts for camera mounts to assure a good thermal
conductivity on the back side of the camera body. Four M3 threaded holes are available on the
camera back side to attach the camera to a mounting facility. It is recommended to use thermal
paste on the contact surface between the camera and the heatsink for maximum thermal
conductivity
