The CAN Bus Cable connects CAN-based robot joint nodes using a defined physical layer, topology, connector assignment, and motion-rated cable construction. This page is an unbranded request-for-quotation entry for an application-specific product type, not a fixed stocked model. Share the assembly, interface, environment, quantity, and documentation requirements so the proposed supply boundary can be reviewed before quotation.
CAN Bus Cable Selection and RFQ Requirements
CANopen describes higher-layer behavior while cable selection remains a physical-layer task; connector pin compatibility must be confirmed separately. The review begins with the function of the item in the robot, then separates mechanical fit, electrical or material requirements, operating conditions, service access, and verification. Similar-looking parts are not treated as interchangeable. Drawings, connector schedules, photographs of mating interfaces, and revision-controlled bills of materials are more useful than a product-family name alone.
How to specify the CAN Bus Cable
Provide the intended function and identify the two interfaces or assembly boundaries that the item connects. The initial review should address the following points:
- Network Topology And Node Locations: provide the drawing, schedule, or requirement that controls this decision.
- CAN Or CANopen Physical Interface: provide the drawing, schedule, or requirement that controls this decision.
- Connector Types, Pin Assignment, And Shield Strategy: provide the drawing, schedule, or requirement that controls this decision.
- Cable Length, Motion Duty, Termination, And Grounding: provide the drawing, schedule, or requirement that controls this decision.
Provide a network drawing showing every node, branch, connector, cable segment, termination location, shield connection, and grounding point. Identify the CAN physical interface and whether the system uses CANopen at the application layer, then supply the connector pin assignment for each device. State cable length, fixed or moving route, flex and torsion duty, jacket environment, and any combined power conductors. Network data rate and topology are system inputs; they are not inferred from cable appearance.
Configuration, Interfaces, and Quoted Scope
A CAN bus wiring harness may include branches, power conductors, or termination only when documented. A CAN communication cable is not assumed to carry actuator power. The quotation should identify the exact deliverable, quantity, revision, and supplied state. It should also list excluded mating parts, customer-provided items, required tools, documentation, and acceptance evidence. Options may be compared, but they remain alternatives until a specific configuration is approved.
A CANopen cable still requires a defined CAN physical layer and connector assignment; CANopen does not create a unique universal cable. A robot joint communication cable can be a point-to-point lead or part of a CAN bus wiring harness. The broader term CAN communication cable does not indicate whether power, termination, branches, or shielding accessories are included.
CAN Bus Cable verification before quotation
- Confirm product identity from controlled drawings, interface definitions, or an approved sample.
- Review mechanical, electrical, material, environmental, and motion requirements as separate evidence sets.
- Record every included component and accessory, including both mating halves where applicable.
- Agree the inspection, continuity, dimensional, visual, functional, or documentation checks relevant to the item.
- Freeze the approved revision before production quantities or interchangeability are discussed.
An Engineering reference is provided as background for preparing the inquiry. It does not define the specification of a proposed item or certify that a generic product meets the application.
Inquiry Checklist
- Robot subsystem, installation location, function, and development phase
- Interface drawings, connector or part identities, revision, and mating direction
- Operating duty, routing or load conditions, environment, and maintenance expectations
- Required included items, tools, files, labels, packaging, and inspection documents
- Prototype quantity, production estimate, destination, and target schedule
Submit the available information through the RobotPiece quote list or contact page. Related product-type inquiries are organized under the Cables category.
A CANopen cable request should name the device connector and pin assignment because CANopen does not define one universal mechanical interface. When replacing a CANopen cable, preserve the network topology, shield and ground arrangement, termination locations, and branch lengths. A robot joint communication cable also needs a stated motion route so that the cable construction and connector support match the moving assembly.
Frequently Asked Questions
Does CANopen require a special connector?
The device and network design determine the connector and pin assignment. Use the controlled device interface and applicable physical-layer recommendations rather than assuming one universal CANopen connector.
Is termination included in the cable assembly?
Only when the network drawing and quotation include it. Termination may be inside a device, in a connector, or in a separate accessory, and duplicate termination can cause problems.
Does the illustration define the delivered robot joint can bus cable?
No. The cover is a conceptual product-type illustration, not a photograph of a confirmed model. Actual dimensions, materials, connectors, finish, markings, included items, and supplied documents must be stated in the approved quotation.
