Original LAPP OLFLEX ROBOT 900 P Cable - High Torsion & Wear Resistance
LAPP (Germany) is a global leader in cable and connection technology. In the robotics industry, the LAPP OLFLEX ® ROBOT series is specifically engineered to withstand extreme bending and torsional stresses. Unlike standard mobile cables, OLFLEX® ROBOT cables utilize an optimized bundle-stranded structure and a high-strength PUR (Polyurethane) outer jacket, enabling simultaneous bending and twisting in three-dimensional space. It is the primary power and signal transmission solution for humanoid robot joints, industrial robot 6th-axis rotations, and high-frequency motion parts in automated production lines.
Product Highlights
- Superior Torsion Performance: The OLFLEX® ROBOT 900 P series can withstand torsional angles of up to +/- 360 ° per meter and has successfully passed tests for 5 million torsion cycles.
- Simultaneous Bending & Twisting: Specialized conductor stranding ensures that internal cores do not shift or break, even when the cable undergoes concurrent bending and twisting movements.
- Extreme Wear & Oil Resistance: The high-quality PUR jacket provides excellent resistance to abrasion, cutting oils, coolants, and microbes, making it suitable for harsh machining environments.
- Space-Saving Compact Design: High-strength insulation materials allow for a smaller outer diameter, ideal for the confined wiring spaces in humanoid and small collaborative robots.
- Wide Temperature Range: Maintains excellent flexibility from -40°C to +80°C, ensuring stable operation under various global climatic conditions.
- Full Communication Support: Includes the ETHERLINE ® ROBOT series for high-speed data transmission, supporting EtherCAT, Profinet, and other robotic bus protocols.

Frequently Asked Questions
Q: What is the difference between OLFLEX® ROBOT and standard drag-chain cables?
A: Drag-chain cables (FD series) mainly handle "linear reciprocating bending," while the ROBOT series handles "simultaneous bending + torsion." Using standard cables in twisting environments causes internal cores to "corkscrew," leading to shorts.
Q: Why is LAPP cable generally more expensive than other brands?
A: The premium comes from the materials. LAPP uses high-purity copper and proprietary PUR jacket formulas to ensure extremely low internal stress and a long service life, reducing downtime costs significantly.
Q: Does this cable support UL/CSA certification?
A: Yes, most models in the ROBOT series (like the F1 version) carry cULus certification, fully meeting the entry requirements for the North American and European markets.
Q: Can shielded cables (DP) also handle large torsional angles?
A: Shielded cables have a metal braid which usually limits torsion to +/- 180°. If your application requires +/- 360°, we recommend unshielded versions or specialized LAPP designs.
Q: How do you guarantee these are 100% genuine German LAPP products?
A: We supply through authorized LAPP channels. All cables have original LAPP branding and batch numbers printed on the jacket, traceable to LAPP Germany or their global factories.
Q: What is the minimum order quantity and lead time?
A: Common specifications are cut-to-length with no MOQ. Stocked items ship within 1 week; factory lead times are typically 4-8 weeks.
