Introduction
The IP67 enclosure was designed to protect Photoneo’s PhoXi 3D Scanner and MotionCam-3D (Color) in harsh industrial
environments. This enclosure was developed by APG Vision in cooperation with Photoneo. This guide provides
instructions on how to operate the Photoneo 3D Sensor inside the enclosure while ensuring the performance of the
device.
Scope of Delivery
The package contains:
■ IP67 enclosure for Photoneo 3D Sensor with the mounting plate
■ 2x thermal bridge (cannot be used with the MotionCam-3D Gen 2)
■ 4x thermal pads (20 x 55 x 1 mm)

Using the Photoneo 3D Sensor
Inside the Enclosure
Temperature regulation
It is recommended that the Photoneo 3D Sensors are kept within the temperature ranges explained in the device
documentation .
Cooling the Photoneo 3D Sensor
Photoneo 3D Sensors are designed for natural convection cooling. This type of cooling is significantly inhibited inside
the enclosure, therefore the scanner requires additional cooling methods.
The enclosure provides a solution for passive cooling via thermal bridges that dissipate the heat generated by the 3D
Sensor to the enclosure itself. Passive cooling is intended for an ambient temperature range of 10°C to 40°C .
Above this range, the scanner needs to be actively cooled using airflow connected to the two holes in the back panel of
the enclosure. Use clean, dry instrument air to cool the enclosure. Recommended air pressure is 35 - 70 kPa (5 - 10 psi).
Passive cooling using the thermal bridges is possible on all models except for the MotionCam-3D Gen 2 line-up due to a
misalignment of the heatsinks and the thermal bridges. In this case, only the active cooling option is available.
Heating the Photoneo 3D Sensor
Below the temperature range, it is required to heat up the 3D Sensor, using one or two electrical heaters with a
thermostat according to the wiring diagram . Besides keeping the 3D Sensor in its optimal operational temperature,
heating also prevents the lenses from fogging. The heaters and the thermostats as well as information on the required
amount of heaters are available upon request.
Additional Optical Element
Photoneo 3D Sensors use Structured light or Parallel structured light technology, that require projection of one or
multiple light patterns to compute 3D information. Inside the enclosure, the laser light passes through an additional
optical element - the glass windows of the enclosure. This causes a slight distortion of the final point cloud. The values in
the following table are theoretically calculated based on the properties of the glass. The practical implications for
applications with additional calibration (e.g. robot-camera calibration, hand-eye calibration) are minor.

Installation Instructions
1. Unpackaging
After you open the package, make sure it contains all the parts from the contents list.
Handle the 3D Sensor and accessories with care.
2. Mounting the Scanner
2.1 Preparation of the Thermal Bridges
Note : It is not possible to install the thermal bridges on the MotionCam-3D Gen 2 line-up. It is mounted only using the
mounting plate in section 2.3 .
Thermal bridges provide passive cooling of the 3D Sensor by dissipating generated heat to the enclosure itself. Use
thermal bridges to cool the 3D Sensor when the ambient temperature is inside the following range: 10°Cto40°C .
Loosen the bracket screws, so there is a 1mm gap between the L brackets. Apply the 8mm wide thermal pad as shown
below. The headless screws shall protrude 1.5 mm from the inner side.

2.2 Mounting the Thermal Bridges on 3D Sensor
Place the brackets on the caps of the device. Make sure the pads are in contact with the aluminum caps on the device.
The 2 headless screws from each side should be gently touching the rim of the aluminum scanner caps. This helps you to
find the correct position of the bracket. Tighten the two bigger screws using an Allen key. Do not tighten the small
headless screws.

4. Preparing the Cable Gland
The following instructions on how to correctly prepare the cable glands are taken from the APG instruction manual .
Always follow the current version of these instructions provided by APG Vision..
■ Determine the diameter of the cable(s) you want to run into the enclosure
■ Select an end mill or drill bit of the same diameter. Selecting a tool that is up to 10% larger will result in an IP
rating lowered to IP65.
■ Mill or drill a hole centered on the split line in the split insert while the cable gland is assembled.
⌑ Mill from the crown nut side
⌑ During milling, back out and clean the mill flutes frequently
⌑ Chill down the end mill before continuing to the next hole.
■ Unscrew the crown nut and remove the split insert
■ Slide the cable connector through the hole in the crown nut, then through the hole in the crown nut body
■ Join the two sides of the slit insert around the cable
■ Press the split insert into the cable gland body
■ Tighten the crown nut back on the body
5. Installing the Cables
■ Protrude cable(s) through the cable gland.
■ Connect the cable(s) to the 3D Sensor connector(s).
6. Placing the 3D Sensor Into the Enclosure
