Major Features

  • The Kvaser Leaf Light HS V2 CB is a high speed USB interface for CAN that offers loss free transmission and reception of standard and extended CAN messages on the CAN bus.
  • Both USB and CAN are connected using 6-way connectors and mate with Molex 51021 PicoBladeTM (e.g. housing 51021-0600 and terminal 50079-8000).
  • 8000 messages per second, each time-stamped with 100 microsecond accuracy.
  • Supports both 11-bit (CAN 2.0A) and 29-bit (CAN 2.0B active) identifiers.
  • High-speed CAN connection (compliant with ISO 11898-2), up to 1 Mbit/s.
  • Galvanic isolation, enhancing protection from power surges or electrical shocks.
  • Local buffering and preprocessing results in high performance and a reduction of time critical tasks for the PC.
