Can bus cable requirements.

Geometry and connection of the double shielded can cable at the double shielded line the user has to take special care that the outer shield is connected with the earth potential only via one connector housing. This article covers the basics of can bus wiring to show a simple can bus wiring diagram and how to wire up a can bus cable. Controller area network physical layer requirements. Prestolite wire brand can bus data cables are designed to the sae j1939 specification utilizing proprietary materials specifically designed for exceptional electrical performance.

Sensor data via the can bus consisting of two wires can low and can high. The broadcasted data is accepted by all other ecus on the can network and each ecu can then check the data and decide whether to receive or ignore it. As a leading special cable manufacturer we are able to design and to produce a customized cable that meet your special requirements. The db9 is also known as 9 pin d sub db 9 de 9 serial connector rs232 connector or null modem connector.

It covers wiring for the common db9 plug and socket often used with can bus test equipment. Can bus 4 physical layer requirements. Halogen free can bus cable for cable. Twisted unshielded or shielded pair designs are available in both 20 awg and 18 awg constructions and may be constructed to specific design requirements.

Controller area network can is a serial network technology that was originally designed for the automotive industry especially for european cars but has also become a popular bus in industrial automation as well as other applications. Can bus control area network is a non addressable system which treats all devices as equal allowing for fast transmission of data. For each device the data in a frame is. Node should be avoided since the bus lines lose termination if the node is disconnected from the bus.

On a car the can bus is usually available via the obd port. A controller area network can bus is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other s applications without a host computer it is a message based protocol designed originally for multiplex electrical wiring within automobiles to save on copper but can also be used in many other contexts. Specifically an ecu can prepare and broadcast information e g. The can bus cables are designed with materials that meet or exceed txl requirements and the impedance return loss and attenuation requirements of the network system.

Due to its robust nature it has been widely adopted in the automotive industry. While all the types listed below are for high flexing automation applications static versions can also be supplied. The shielding reduces the harmful effect of emi or rfi interference.
