Electrical Interface
Power Supply and Operating Voltage
The OS2 Rev 06 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. The maximum input voltage is 34V for the OS2 sensor. When used without the provided interface box, ensure that the power supply is compliant with the operating voltage specified above and allows to supply at least 20 W.
Connection through the Interface Box
The Interface Box that accompanies the OS2 is designed to allow the sensor to be operated for test and evaluation purposes in indoor environments only. It can be connected to the sensor with a cable equipped with connectors on both ends. It allows the sensor to be powered up and provides access to the sensor gigabit Ethernet Interface via a standard RJ45 connector. DC Power to the sensor is provided to the Interface Box by the accompanying 24V DC power supply.
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 Power Supply and Operating Voltage
Warning
Ouster is not responsible for any errors in wiring as a result of bypassing the Interface Box and this activity may result in a voiding your warranty if it results in damage to the sensor. The following guidelines for direct cable connection assume use of the Ouster-provided 24V 1.5A power supply. Ouster cannot be held responsible for damage to the device if alternate is used.
