Listen to any CAN bus without damaging the wires or disturb the CAN bus signals

Listen to the data traffic on a CAN bus without making an electrical connection to the physical bus. The sensor is easy to mount, attached to the existing CAN wires with a smart click-fit locking function and provides galvanic isolation to the CAN bus it is listening to. The device will eavesdrop all data on the bus to a dedicated CAN bus. No configuration is required!

CAN-KEY can be used with any ISO 11898-2 compliant CAN bus, such as SAE J1939 or CANopen.

Many of the devices available on the market today need to have physical connection to the conductors of the CAN bus wires to be able to read the data. This will break the insulation of the wires which means it get exposing the conductors to the surrounding moisture/air humidity.

If the insulation of the wires in the original system is tampered with, you will have the possibility that the connected device may disturb the CAN bus and it will in most cases also void the warranty of the system it is connected to.

CAN-KEY have a small sensor part inserted between the CAN-High and CAN-Low wires and listens to the bus by sensing the extremely small capacitance change during data communication.
