Page 3: Important Safety Information
1 Important Safety Information 1.1 Safety & Legal Notices The OS2-128, OS2-64, and OS2-32 have been evaluated to be Class 1 laser products per 60825-1: 2014 (Ed. 3) and operate in the 865nm band. L’OS2-128, l’OS2-64, et l’OS2-32 répondent aux critères des produits laser de classe 1, selon la norme IEC 60825-1: 2014 (3ème édition) et émettent dans le domaine de l’infrarouge, à... - Page 4 Use of controls, or adjustments, or performance of procedures other than those specified herein, may result in hazardous radiation exposure. Use of the OS2 is subject to the Terms of Sale that you agreed and signed with Ouster or your distributor/integrator. Included in these terms are the prohibitions of:...
- Page 5 Sensor Components. Electromagnetic Compatibility: The OS2 is an FCC 47 CfR 15 Subpart B device. This device complies with part 15 of the FCC Rules. Operation is subject to the following conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

When the sensor is running, and the laser is operating, a faint red flickering light may be seen behind the optical window. Note that the OS2 utilizes an 865nm infrared laser that is only dimly discernible to the naked eye. The sensor is fully Class 1 eye safe, though Ouster strongly recommends against peering into the optical window at close range while the sensor is operating. -

Page 9: Mounting Guidelines
The shape of any heatsink should maximize the surface area for free and forced convection while being thick enough to allow the heat to conduct through the material. If you have questions about your specific mounting situation please contact the Ouster at sup-... -

4.1 Power Supply and Operating Voltage The OS2 Rev 05 Sensors are meant to operate at 12V and 24V nominal input voltage. A low voltage warning will be triggered if the voltage at the sensor connector drops below 9.5V. The sensor will shut down if this input voltage drops to 9V. -
Page 11: Direct Cable Connection And Pinout
4.3 Direct Cable Connection and Pinout The OS2 can be operated without the use of an Interface Box. In this case, a “pigtail” cable should be used and wires should be connected by the user following the Pinout presented below. When used with direct cable connection, the sensor should still be operated within the operating voltage specified in section :ref: ‘Power Supply and Operating Voltage’... -

Page 17: Interface Box
7.2 Interface Box The Ouster Interface Box is a support tool for use in laboratory environments to assist customers in evaluating Ouster’s LiDAR sensor products and in the development of software. The Interface Box is not protected from ingress of moisture or solid particles and is not intended for use outdoors. - Page 18 Warning: RISK OF FIRE OR ELECTRIC SHOCK. DO NOT CONNECT THE GPS CONNECTOR DI- RECTLY TO AN ANTENNA. Components Figure7.2: Interface Box Specification 1 - Sensor connector. Connect to the sensor with a double-ended connector cable. 2 - Ethernet jack. RJ45, gigabit speed (1000base-T). 3 - VIN Barrel Jack.

- Page 21 Electrical Characteristics The Type 1 and Type 2 cable Interface Boxes are rated 24 Vdc, 1.1 A and supports all Ouster sensors. The Type 3 cable Interface Box is rated 12 Vdc, 3.3 A and 24 Vdc, 1.1 A. This Interface Box supports 24V operation on all Ouster sensors, and 12V operation for Rev 05 sensors only.
- Page 22 If purchasing a power supply locally, it should be supplied with an appropriate power supply cord or cordset for use with the power supply. If it’s necessary to select a power supply cordset for the Ouster supplied power supply, it should be safety certified by a test house acceptable to the local region of use, supplied with an IEC 60320, Type C6 cord connector to mate with the power supply and a plug for connection to an AC outlet with an earthing contact/pin.
