Orbbec Gemini 338Le Gigabit Ethernet PoE 3D Depth Camera
Orbbec Gemini 338Le is an industrial stereo 3D depth camera built around Gigabit Ethernet and PoE for networked robot and logistics installations. Its IR-bandpass optical design reduces out-of-band ambient-light interference in scenes with mixed lighting.
The camera combines a 95 mm stereo baseline, up to 1280 × 800 depth at 30 fps, an ideal 0.25–6 m working range and an IP67-rated enclosure. For the published ingress protection, use properly fitted cables and protect any unused connector; validate the network, power and synchronization configuration before deployment.
An onboard MX6800 depth processor, global-shutter imaging and IMU provide building blocks for robot perception. The host remains responsible for mapping and decisions; select the PoE or DC wiring route, network timing and protected connectors for the installation.
Features
- IR-bandpass optical design: Reduce out-of-band ambient-light interference in warehouse and inspection scenes.
- Gigabit Ethernet and PoE: Use an M12 X-coded network connection and IEEE 802.3af PoE, or the specified separate DC input.
- High-resolution stereo depth: Output up to 1280 × 800 at 30 fps or 848 × 530 at 60 fps.
- Defined depth range: The ideal working range is 0.25–6 m; the broader 0.25–20 m+ figure depends on scene conditions.
- IP67 industrial enclosure: Use appropriately rated, secured cables and protect any unused connector to retain the specified protection.
- Hardware synchronization and PTP: Coordinate networked cameras with verified timing and host configuration.
- On-camera MX6800 processing: Supply depth data to the host, which remains responsible for navigation and recognition tasks.
- Global-shutter capture and IMU: Provide synchronized imaging and motion inputs for robot perception.
- Conditioned spatial precision: Factory-calibration figures are ≤0.8% at 2 m and ≤1.6% at 4 m at the stated resolution and ROI.
- PoE or DC power path: Plan IEEE 802.3af PoE or 9–24 V DC at the manufacturer-specified current.

Applications

Warehouse measurement
Capture depth information for package and stacked-goods measurement where ambient lighting can vary; calibrate the complete measurement workflow for target materials.

Autonomous forklifts
Evaluate pallet and load geometry for loading, unloading and material-handling perception in warehouse environments.
AMRs and AGVs
Use networked RGB-D data for obstacle sensing and local scene understanding, subject to robot-level localization and safety design.
Industrial inspection
Position the IP67-rated camera in a fixed inspection station and route depth data over the industrial Ethernet connection.
Multi-camera depth stations
Coordinate multiple views with the supported synchronization and PTP features, then confirm network bandwidth, timing and calibration.
Outdoor automation research
Test depth sensing in changing ambient light and weather with correctly sealed connectors; verify range against reflectance and exposure conditions.
Integration
- Choose one power path - Use IEEE 802.3af PoE or the specified 9–24 V DC supply. Protect the unused power connector when PoE is selected and follow the manufacturer wiring instructions.
- Validate industrial Ethernet - Plan M12 X-coded mating cables, link bandwidth, network addressing and host-side software before treating the camera as plug-and-play.
- Coordinate multiple cameras - Use hardware synchronization and PTP as available, then verify timestamps, exposure, traffic and calibration in the full system.
- Preserve IP67 protection - Install matching rated cables and secured connectors; an unsealed cable or unused port invalidates the expected ingress protection.
- Design for thermal conditions - The manufacturer specifies −10°C to 50°C at 15 fps and −10°C to 45°C at 30/60 fps. Assess enclosure ventilation and duty cycle.
- Use model-supported software - The official SDK v2 and ROS2 wrapper list Gemini 338Le support. Match firmware, network configuration and the documented launch profile.
