01 - VBOX Speed Sensor Introduction Speed Sensors (VBSS25/VBSS100) The Racelogic Speed Sensors feature versions with 25 Hz and 100 Hz update rates. Based on a range of high-accuracy GNSS engines, you can use the speed sensor to perform non-contact sensing of velocity, providing signal output data on CAN, analogue, digital and serial.

Interfacing with the VBOX Speed Sensor You can use the VBOX Speed Sensor in several different ways, and it is common for the end-user to integrate the speed sensor connector into their own wiring harness. You can purchase a mating connector, Deutsch ASDD606-09PN, from Racelogic for this purpose.

Note: During extended use, the Speed Sensor's case may become hot. This is normal, however, it is good practice to mount the VBOX Speed Sensor in a position where it has sufficient airflow around the case.
