The Kvaser Air Bridge Light HS M12 (EAN 73-30130-01141-0) 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 version without the (FCC) suffix: Kvaser lists it as certified for the EU and the US. A separate (FCC) edition with its own EAN is listed as certified for the US. Pertech is the authorized Kvaser sales representative in Israel.

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
- Projects that need EU radio approval
