85444929
The CANBUS-HFU PROFIBUS PUR Chain Cable is a specialized data bus cable designed for reliable, high-speed communication in demanding industrial automation environments, particularly within moving cable carriers. Featuring precise impedance characteristics, twisted pair construction, and robust overall shielding (HFU design), it ensures signal integrity for CANopen, DeviceNet (CAN physical layer), and PROFIBUS DP networks under constant flexing and exposure to oils, chemicals, and abrasion.
▍Technical parameters
Item | Value |
Model | |
Voltage | 250V |
Temperature Range | Fixed installation: ﹣50℃~90℃ Moving installation: ﹣40℃~90℃ |
Minimum bend radius | Fixed installation: 8x cable outside diameter Moving installation:15x cable outside diameter |
Maximum moving speed
| Unsupported speed:8m/s Gliding speed:5m/s Acceleration:75m/s² Identity impedance:120Ω |
Optimized Signal Integrity: Precisely twisted pairs (A/B lines) with controlled impedance (e.g., 120Ω for RS-485/PROFIBUS) minimize signal reflections and crosstalk.
High Flex PUR Design (HFU): Tough polyurethane (PUR) outer jacket and flexible construction withstand millions of flex cycles in drag chains.
Superior Shielding: Effective overall foil + braid (HFU) or double braid shielding provides excellent immunity against EMI/RFI and minimizes emissions.
Robust Protection: Resistant to oils, greases, coolants, abrasion, and many industrial chemicals.
Clear Color Coding: Standard violet PROFIBUS jacket or distinct color coding for easy network identification and installation.
Compliance: Meets PROFIBUS guidelines and relevant CAN physical layer specifications.
CANopen and DeviceNet networks in robotics and machinery
PROFIBUS DP networks connecting drives, I/O, sensors on moving platforms
Communication between PLCs and remote I/O stations within cable carriers
Data transmission in automated assembly lines, packaging machines, material handling
Control signals for servo drives and motors in flexing applications
Industrial Ethernet physical layer alternatives (where appropriate)
Q: Can this cable be used for both CAN and PROFIBUS?
A: Yes, its design (twisted pair, 120Ω impedance, shielding) is compatible with the physical layer requirements of both CAN-based systems (like CANopen, DeviceNet) and PROFIBUS DP.
Q: What is the maximum data rate/bus length supported?
A: Maximum speed and distance depend on the specific protocol (e.g., PROFIBUS DP up to 12 Mbps, CAN typically 1 Mbps max) and network configuration. Always adhere to the protocol's guidelines for cable length vs. baud rate.
Q: Why is PUR better than PVC for bus cables in chains?
A: PUR offers superior flexibility, cold resistance, oil/chemical resistance, and abrasion resistance compared to standard PVC, making it far more durable in continuous flexing drag chain applications.
Q: How are the bus terminators connected?
A: Terminating resistors (usually 120Ω) are required atbothphysical ends of the main bus trunk line. They are connected across the Data+ (A) and Data- (B) conductors. The shield is typically grounded at one point.
