Controller Area Network (CAN) bus is a fieldbus system developed by Bosch, which partnered with Intel to introduce it in 1986. The goal was to reduce the cable harnesses in cars in order to reduce cost and weight. Over time, various CAN protocols became established, especially in security-related areas. In 1994, Bosch headed the introduction of the CANopen protocol for automation technology. CAN bus is used primarily in automation technology. CAN bus systems are also found in vehicles used in industry, such as forklifts and lifting work platforms.

Transmission lengths The topic of maximum bus cable transmission length is often underestimated. In general, caution should be exercised, since the maximum cable length can be strongly linked to cable type. A cable for fixed installation always has a lower dampening than flexible cables, which are designed for constant movement. As a result, the transmission length is shorter than with a cable for fixed installation.
Depending on cable range, chainflex CAN bus cables are mechanically designed for travels of up to 400m or more, but bus system data rate decreases as cable length increases. For fixed installation, copper cables can reach up to 500m. Then the maximum transmission speed is still 125Kbps, while a cable length of 40m still allows a data transfer rate of 1Mbps. Our experience with highly flexible CAN bus cables for energy chains shows that cable length can be significantly shorter. Depending on transmission speed, a moving CAN bus cable can be up to 50m. However, this length may vary up and down depending on environmental conditions and application requirements.
chainflex CAN bus cables can be ordered by the foot on a drum or cable ring from 1ft with no cutting charge or minimum quantity surcharges. igus also offers these cables as harnessed readycables. Any chainflex PROFINET cable can be ordered as a ready-harnessed cable in a desired length, no minimum quantity. The readycable online shop has a selection of cables and connectors. A filter function facilitates type selection.
