 The Kvaser Air Bridge Light HS M12 is a configuration-free wireless CAN bridge that uses a dust and water-tight M12 connector to connect CAN networks. 

Comprising a preconfigured pair of plug-and-play units, with integrated antennas and rugged housings, the Kvaser Air Bridge Light HS M12 ensure the rapid exchange of raw CAN data in situations that make wired connection unsuitable or challenging, such as CAN cabling that experiences high environmental abrasion.

Employing a proprietary 2.4G radio and frequency hopping mechanism, the Kvaser Air Bridge Light HS controls the data rate, radio packet format, output power and pairing method to achieve predictable latencies, without sacrificing stability or range. Transmission range is as much as 70 m, with a maximum data rate of 1200 messages per second and a packet latency of 4.8 ms. This makes the Air Bridge effective in infrastructure and control applications, where accurate message delivery times are essential, and a viable alternative for optical cable in some situations.

There are two versions: (01141-0) Kvaser Air Bridge Light HS M12 is approved for the European Union, while (01148-9) Kvaser Air Bridge Light HS M12 (FCC) complies with US certification. Both share the same functionality but have different radio transmission schemes due to regulatory differences.
