Can Bus Cable Length

Can bus maximum length.

Can bus cable length.

Cable length 40000 kbit s 1 m bitrate in kbit s bitrate given in kbit s as well. The bits per second bps signalling rate determines the maximum length of a cable run for a can bus. Cd systems provides a nice overview. There is one rule of thumb.

Bus length l cable stub length l node distance d 1 mbit sec. Though the iso11898 standard specifies a maximum bus length of 40m and maximum stub length of 0 3m at 1mbps. 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. 2 in the customer application the iso1050 output has two branch output lines.

In this formula a typical transceiver propagation of 25ns and a typical cable propagation of 5 ns m is used for calculation. In other words the cable length is restricted by the speed of light. Does this optional line need any termination though i think it s okay to leave it open. The message is transmitted serially onto the bus using a non return to zero nrz format and may be received by all nodes.

As the data rate increases the maximum bus length drops rapidly. 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. The devices that are connected by a can network are typically sensors actuators and other control devices. One output line is optional and ordinarily not use.

1 x 2 x 0 50mm can bus cable violet pur. The improved can fd extends the length of the data section to up to 64 bytes per frame. 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. Maximum cable length at a speed of 1 mbit s a maximum cable length of about 40 meters 130 ft can be used.
