The Kvaser Air Bridge Light HS M12 (FCC) (EAN 73-30130-01148-9) is a configuration-free wireless CAN bridge whose two units each end in a dust and water resistant M12 connector. The two units arrive paired at the factory, so the bridge works as soon as both ends are plugged into their CAN networks. A proprietary 2.4 GHz radio protocol with frequency hopping and diversity keeps latency low and predictable and holds a strong signal at long range. This is the US edition: Kvaser lists it as certified for the United States, and the FCC version is tested to part 15 of the FCC rules. For projects in Europe, choose the Air Bridge Light HS M12 without the (FCC) suffix, which Kvaser lists as certified for the EU and the US. Pertech is the authorized Kvaser sales representative in Israel.

- Plug and play: no driver, no setup and no configuration step
- Detects the bus speed by itself at 125, 250, 500 or 1000 kbit/s
- Proprietary 2.4 GHz frequency-hopping protocol with diversity for low, predictable latency
- Point to point radio link through an internal antenna, output power up to about 18 dBm
- High-speed CAN (ISO 11898-2) up to 1 Mbit/s, 11-bit and 29-bit identifiers
- M12 connector on each unit, sealed against dust and water
- Each unit draws its power from the CAN bus connector
- Rugged aluminum housing rated IP65, galvanically isolated
- Works with J1939, CANopen, NMEA 2000 and DeviceNet networks
- Error frames and arbitration information stay on the local bus and are not sent over the radio link
- Radio approval: US (FCC)
Where the Air Bridge Light HS M12 fits
- Replacing CAN cables that wear out on moving, rotating or articulated machines
- Outdoor, marine and off-highway installations that need sealed connectors
- Linking two CAN networks where routing a cable is hard or impractical
- Control applications that depend on consistent message delivery times
- Some cases where an optical cable link would otherwise be considered
- US installations that need FCC radio approval
