Customer demand for the ability to capture CAN signal with non-contact technology is growing as automobiles incorporate more electronic components and transition to electric drivetrains.

The number of onboard ECUs continues to rise as electronic control of vehicles becomes more sophisticated. Controller Area Network (CAN) is a network that allows such ECUs to communicate with each other. There are a growing number of opportunities to use information from CAN communications in vehicle development and evaluation thanks to the ability to acquire important information such as sensor and control data. In the past, acquiring CAN signals meant either stripping back signal line insulation so that probes could be placed in contact with conductors or inserting branching harnesses into signal lines. However, stripping wires to establish contact meant that the wires were no longer protected by insulation, and using branching harnesses made preparing for testing a time-consuming proposition.
