Electrical Interface

Power Supply and Operating Voltage

The Ouster Sensors are designed to operate between 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 Ouster sensor. When used without the provided interface box, ensure that the power supply is compliant with the operating voltage specified above and is at least 20 W.

Note

If operating at cold conditions the peak power consumption is between 22 W and 28 W. Peak power consumption is 28 W if operated at -40ºC for Rev7 OS-Dome, OS-0 and OS-1 (-20ºC for OS-2). Ouster recommends use of power no less than 30W if using in outdoor conditions. Please contact our Field Application Team can answer your questions and provide guidance for achieving proper operations.

Connection through the Interface Box

The Interface Box that accompanies the sensor 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. 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 Ouster sensor can be operated without the use of an Interface Box. In this case, a “pigtail” cable should be used 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.

Note

A black shielding drain wire is included for convenient bonding of the braided shield as required. It’s important to note that the drain wire is not connected to any pin in the sensor. The drain wire can be left unconnected unless the user wants to use it for EMI/EMC tests.

Warning

Ouster is not responsible for any errors in wiring as a result of bypassing the Interface Box and this activity may result in voiding of 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 an alternate is used.
