Allen-Bradley Cables: Overview
Allen-Bradley, a Rockwell Automation brand, offers a comprehensive range of industrial cables designed for robust connectivity in automation systems. These include cordsets, patchcords, network media, power cables, and motion control cables, supporting protocols like Ethernet, DeviceNet™, ControlNet™, and safety systems. They are engineered for harsh environments, ensuring reliable signal transmission, power delivery, and device integration.
Product Detailed Description
Allen-Bradley cables encompass several categories tailored to industrial needs:
- DC Micro (M12) Cordsets & Patchcords (Bulletin 889): Secure, overmolded connectors for field devices. Available in straight or right-angle configurations with 4- or 5-pin options. Jackets in various colors (e.g., yellow for standard, red for safety). Used for quick, plug-and-play connections.
- AC Micro (1/2″) Cordsets & Patchcords (Bulletin 889): Provide power and signal connections for sensors and actuators. Options include 22 AWG or 18 AWG conductors, shielded or unshielded, with straight or right-angled connectors. Special coiled versions for dynamic applications.
- Kinetix® Cables (Bulletin 2090): High-flex servo and feedback cables for motion control. Feature SpeedTEC® DIN connectors for one-quarter-turn assembly. Include standard and continuous-flex types certified to global standards (e.g., IP67, UL, DESINA).
- Network Media Cables: Support Ethernet, ControlNet™, and DeviceNet™. Include raw spools, patchcords, and accessories like splitters and tees.
- Power Media Cables: Plug-and-play for three-phase motors, ArmorStart® controllers, and 24V DC auxiliaries. Include trunk/drop cables, tees, and receptacles.
- Industrial USB Cables (Bulletin 9300): Replace serial adapters for direct PC-to-device connections in programming and setup.
- On-Machine™ M12 Cables: Twisted-pair Ethernet cables with IP67 connectors for high-flex, on-machine use.
- Cable Spools (Bulletin 889): Raw cable stock (e.g., PVC, ToughWeld™) for custom assembly with field-attachable connectors.
These cables are built with materials like PVC, TPE, or PUR jackets for durability, and many follow IEC color coding for easy identification.
Product Parameters
Key specifications vary by type, but common parameters include:
| Parameter | Description | Typical Values |
|---|---|---|
| Conductor Size (AWG) | Wire gauge for current handling | 10, 14, 18, 20, 22 AWG |
| Shielding | Protection against EMI/RFI | Unshielded, shielded (foil or braid, up to 85% coverage with tinned copper) |
| Connector Types | Interface standards | M12 (DC Micro), 1/2″ (AC Micro), 7/8″ Mini, M8 Pico, M23, RJ45, SpeedTEC DIN |
| Pin Configuration | Number of pins/contacts | 4-5 pins (DC), 3-5 pins (AC), 7-conductor flat for in-cabinet |
| Cable Length | Standard lengths | 0.3m to 30m (1-100 ft); custom spools up to 1000m |
| Bend Radius | Minimum for flexing | 7.5-10x outer diameter (OD); continuous-flex up to 20 million cycles at 10x OD |
| Jacket Material | Environmental resistance | PVC (oil/flame-retardant), TPE/PUR (high-flex), ToughWeld™ (weld-resistant) |
| IP Rating | Ingress protection | IP20 (in-cabinet), IP67 (on-machine/exposed) |
| Voltage/Current Rating | Power handling | Up to 600V; 4-16A depending on AWG |
| Temperature Range | Operating limits | -40°C to +105°C (-40°F to +221°F) |
| Certifications | Compliance standards | UL, CSA, CE, DESINA (color coding), tray cable/exposed run rated |
For example, a typical DC Micro cable (889D-F4AC-5) is 5m long, 4-pin female straight, unshielded PVC yellow jacket, IEC-coded.
Product Advantages
Allen-Bradley cables provide significant benefits for industrial automation:
- Ease of Installation: One-quarter-turn connectors (e.g., SpeedTEC) and plug-and-play designs reduce wiring time by up to 80%, minimizing errors and material waste.
- Durability and Reliability: High-flex options endure 20 million cycles; IP67-rated for harsh environments with vibration, noise, and EMI resistance (85% braid coverage). Oil-, flame-, and weld-resistant jackets extend lifespan.
- Safety and Identification: Red jackets for safety circuits; DESINA-compliant colors for quick visual identification on the plant floor.
- Versatility: Single-cable solutions for power/signal (reducing clutter); compatible with global standards (UL, tray cable) for exposed runs and on-machine use.
- Simplified Maintenance: Modular components (e.g., field-attachables) allow quick repairs; USB cables eliminate adapter stacks for faster setup.
Overall, they enhance machine design, reduce downtime, and support scalable systems.
Precautions and Notes
To ensure optimal performance and safety:
- Installation Guidelines: Use proper torque on connectors to avoid damage; maintain minimum bend radius to prevent conductor breakage. For continuous-flex cables, avoid exceeding 10x OD in dynamic applications.
- Environmental Considerations: Select jacket materials based on exposure (e.g., PUR for oils/chemicals, PVC for general use). Avoid exceeding temperature/voltage ratings to prevent insulation failure.
- EMC/EMI: In noisy environments, use shielded variants and ground properly; test for 85% coverage efficacy.
- Safety Applications: Use red-jacketed cables only for designated safety circuits; verify IP ratings for wet/dusty areas.
- Compatibility: Confirm connector types match devices (e.g., M12 for sensors); for programming cables, ensure OS/driver compatibility (e.g., RSLogix).
- Maintenance: Inspect for cuts/abrasions regularly; do not exceed spool lengths without connectors to avoid signal loss. Consult Rockwell Automation literature for model-specific warnings.
Failure to follow these may void certifications or cause system faults.
Product Applications
Allen-Bradley cables are integral to diverse industrial scenarios:
- Sensor and Device Connectivity: Linking proximity/photoelectric sensors, limit switches, and I/O modules in assembly lines and packaging machines.
- Motion Control Systems: Servo motor/actuator connections in robotics, CNC machines, and high-speed conveyors (Kinetix cables for flexing arms).
- Network Infrastructure: Ethernet/DeviceNet™ backbones in factories for data exchange between PLCs, HMIs, and controllers.
- Power Distribution: Three-phase motor circuits and 24V DC feeds in distributed motor controls (e.g., ArmorStart®) for pumps, fans, and conveyors.
- Safety Systems: Emergency stops and guards in hazardous areas, with red coding for compliance.
- Programming and Diagnostics: USB cables for PLC setup (e.g., SLC/MicroLogix series) in maintenance and commissioning.
- On-Machine and High-Flex Uses: Dynamic environments like welding cells or automotive assembly, where vibration and movement are constant.
These applications span manufacturing, automotive, food/beverage, and energy sectors, supporting Industry 4.0 connectivity. For specific models, refer to Rockwell Automation’s product selector tools.
