Can Bus Cable Length

Though the iso11898 standard specifies a maximum bus length of 40m and maximum stub length of 0 3m at 1mbps.

Can bus cable length.

1 x 2 x 0 50mm can bus cable violet pur. In other words the cable length is restricted by the speed of light. Maximum cable length at a speed of 1 mbit s a maximum cable length of about 40 meters 130 ft can be used. Cable length 40000 kbit s 1 m bitrate in kbit s bitrate given in kbit s as well.

The devices that are connected by a can network are typically sensors actuators and other control devices. Can bus maximum length. If you need longer cables for your application confirm with the ni product documentation for your device the xnet manual and or the sae j2411 or iso 11898 cia ds 102 and devicenet specifications. Bus length l cable stub length l node distance d 1 mbit sec.

Cd systems provides a nice overview. The message is transmitted serially onto the bus using a non return to zero nrz format and may be received by all nodes. One output line is optional and ordinarily not use. 40 meters 131 feet 0 3 meters 1 foot 40 meters 131 2 feet.

2 in the customer application the iso1050 output has two branch output lines. As the data rate increases the maximum bus length drops rapidly. A low can bus data rate for example 10 kbps will allow the bus to operate at a long distance of 6700 metres between the two ends of the bus. This is because the arbitration scheme requires that the wave front of the signal can propagate to the most remote node and back again before the bit is sampled.

Garmin carlisle can24tst120 can bus cable garmin recommends the use of p n can24tst120 cit cable to interface the can bus on g3x g5 gmu11 gad29b gfc500 gmc507 gsa28 etc. Using this results in 40m for 1mbit s or 320m for 125kbit s. Solution national instruments sells can cables of 1m and 2m length. Does this optional line need any termination though i think it s okay to leave it open.

There is one rule of thumb. The improved can fd extends the length of the data section to up to 64 bytes per frame.
