About SAB Brockskes
SAB Brockskes Industrial Automation Cable Systems
SAB Bröckskes is a family-operated German manufacturer founded on June 4, 1947, by Peter Bröckskes in Viersen as a one-man electrical plant engineering business. Initially producing burglar alarm systems for private houses and industrial sites, the company expanded in 1950 to include thermocouples and resistance thermometers, then in 1958 began producing industrial cables with just 8 employees. Today, SAB Bröckskes is one of the world's leading manufacturers of special cables and wires, with more than 550 employees and sales in over 100 countries. The company remains family-operated in the third generation, with Peter Bröckskes and Sabine Bröckskes-Wetten managing operations.
The core product portfolio spans three major cable families for industrial automation and drive technology: Drag-chain cables for continuously flexible and torsion-resistant robotics systems and permanently flexible applications requiring 10–50+ million bending cycles; Servo and motor cables designed per IEC 60228, ISO 1346, and DIN 76 specifications for ac/dc power transmission and high-frequency signal integrity in variable-frequency drive systems; Control cables for digital data transmission, sensor networks, and pilot-control circuits in machine tools and manufacturing systems.
SAB's flagship innovation in response to Industry 4.0 digitalization is its industrial Ethernet cable portfolio: Category 6A, 6A+, 7, 7A, and 7A+ cables engineered for robust and high-speed data transmission in factory floors, robotics cells, and machinery networks. These cables tolerate mechanical stress (crush/bend/torsion from machinery motion), electromagnetic interference (from high-voltage drives, welding equipment, radio transmitters), and harsh chemical environments (oils, coolants, washdown agents) while maintaining gigabit-rate data rates (up to 10 Gbps for Cat 7A+). Testing per ISO 11801-2 and TIA-942 standards ensures repeatability across production batches.
SAB also manufactures cable assemblies and ready-to-connect harnesses for industrial applications, offering custom processing of cables and wires into complete power, signal, and data transmission solutions. This cable-assembly capability enables OEM integrators to simplify bill-of-materials (BOM) and reduce field assembly labor, particularly for modular automation systems and plug-and-play industrial IoT deployments.
ChatMRO instantly maps your machinery motion profile (stationary / light occasional flex / continuous drag-chain / high-torsion robotics), duty cycle (millions of flex cycles needed), data requirements (gigabit Ethernet for Industry 4.0 / legacy analog signals), and environmental hazards (temperature, moisture, chemical spray, vibration) to SAB's drag-chain, servo, and Ethernet cable portfolios, enabling rapid specification with full compliance documentation and lead-time forecasting for custom harness builds.

Frequently asked questions
What is the difference between a SAB drag-chain cable rated for 5 million cycles versus 20 million cycles, and how do I calculate my machinery's actual cycle requirement?
Drag-chain cables are rated for maximum bending stress cycles to insulation breakdown: 5M cycles is entry-level for occasional-flex machines (pallet movers, light indexing systems, <100 cycles/day); 10–20M cycles covers continuous-duty robotics, transfer lines, and overhead conveyors (500+ cycles/day); 50M+ cycles is for high-speed assembly and stamping automation (2,000+ cycles/day). Calculate your need: identify the cable's active motion cycle/day, multiply by working days/year, divide by the cable's rated cycle life, and add a 50% safety margin. For example, a robotic arm with 200 cycles/hour × 8 hours/day × 250 working days/year = 400,000 cycles/year; a 10M cable lasts ~25 years, a 5M cable ~12 years. SAB provides cycle-requirement calculators; ChatMRO's cable lifecycle guides recommend the rating based on your OEM's documented duty cycle.
Can SAB Ethernet cables be mixed with standard Ethernet cables (Cat 5/6) in the same industrial system, or must all segments use industrial-rated cable?
Standard commercial Ethernet cables (Cat 5/6) use PVC insulation and minimal shielding, designed for office environments at 20–25°C and static routing; industrial SAB cables use polymer insulation and multi-layer shielding, rated for temperature extremes, EMI, and flex stress. Mixing standards creates performance bottlenecks: the entire network's throughput is limited by the slowest/weakest segment, and impedance mismatches between standard and industrial-rated cables introduce reflection noise and packet loss. Best practice is to standardize on SAB industrial-rated cables throughout the factory floor, with standard cables only in climate-controlled control rooms. If budget constraints prevent full upgrade, at least use SAB cables on machinery-proximal runs (within 5 m of any motor, VFD, or power conductor) where EMI is highest; ChatMRO's network design guides map optimal cabling strategies for mixed-age manufacturing facilities.
How do I verify that a SAB drag-chain cable is routed with the correct bend radius, and what happens if the radius is too tight?
Every SAB cable is labeled with a minimum bend radius (MBR) in inches or mm, varying by conductor count and insulation thickness—typical values range 50–200 mm. The cable's sheath and insulation are engineered to accommodate this bend stress; exceeding MBR causes internal conductor strain, cracking of insulation in the bend area, and premature shorts within months. Measure your cable path's tightest bend radius (lowest point of the bend curvature) with a flexible ruler or radius gauge and compare against the cable's label; if MBR is 80 mm but your bend is 60 mm, either reroute the cable with a gentler curve, use a larger-diameter pulley or support bracket to increase radius, or upgrade to a more flexible cable variant. SAB provides CAD-based bend-radius checking tools; ChatMRO's routing guidelines include bend-radius calculators and pulley-sizing charts for common robotic and transfer-line geometries.
What is Industrial Gigabit Ethernet, and how does it differ from standard gigabit networking in terms of cable specification?
Standard gigabit Ethernet (Cat 6A: 500 MHz bandwidth, 10 Gbps theoretical max over 55 m) works fine in office/data-center environments at stable temperature and zero vibration. Industrial Gigabit Ethernet (SAB CATLine Cat 7A: 600 MHz bandwidth, 10 Gbps over 100 m, tested for temperature swing -10 to +60°C, vibration, EMI, oil/coolant immersion per ISO 11801-2) is engineered for factory floors where machines, VFDs, and welders generate high EMI and environmental stress exceeds office specs. Industrial cable maintains signal integrity and data-rate performance under these conditions; standard cables degrade, losing packets and requiring network reboots (costly downtime in production). For any factory-floor deployment, specify industrial-rated Cat 6A/7A cables from the outset; mixing standard and industrial creates troubleshooting nightmares and reliability unpredictability.
How often should SAB servo and motor cables be inspected for signs of degradation, and what are the warning signs?
SAB servo/motor cables should be visually inspected monthly for tears in the outer sheath, discoloration or hardening of insulation (sign of thermal stress), and any exposed conductors. Rotate cables (re-position them in cable trays or drag chains) annually to equalize wear and prevent localized stress concentration. For high-speed servo systems, perform insulation-resistance testing annually using a megohmmeter (typically 500V DC applied, reading should remain >100 megohms per IEC 60811-2-1); if resistance drops below 50 megohms, retire the cable immediately (high failure risk). High-temperature motor cables (operating at >80°C continuously) should be checked biennially, as insulation ages faster at elevated temperature. ChatMRO's cable maintenance schedules align servo/motor cable inspection with facility-wide predictive maintenance and spare-parts planning cycles.
