Purpose-Built Hybrid Cable for Robotic Drive Systems
The Festo NEBM-L5G14-EH-10-Q6N-LE12 (part number 8181672) is a 10-meter hybrid connecting cable engineered for demanding robot applications. It combines power and signal lines into a single shielded assembly, reducing wiring complexity on moving axes. With a straight hybrid socket on the field device end and an open cable end on the control side, this cable is designed for straightforward integration between a servo drive and its associated components.
Electrical and Mechanical Specifications
The cable supports a DC operating voltage range of 0 to 48 V and carries a current rating of 7.6 A at 40 °C. Its surge resistance of 1.5 kV provides protection against transient overvoltages, while the overvoltage category I and contamination level 3 ratings align with typical industrial control cabinet environments. The cable is fully shielded, which helps maintain signal integrity in electrically noisy surroundings.
Mechanically, the cable features a gray TPE-U(PUR) sheath with a PP insulating layer, offering flexibility and durability. It is suitable for energy chains, with a minimum bending radius of 42 mm for fixed installation and 78.75 mm for flexible routing. The cable diameter is 10.5 mm ±0.3 mm, and the conductor configuration is 4 x 0.5 mm² + 2 x 0.5 mm² + 6 x 0.15 mm², with wire ends terminated with cable end sleeves. The product weight is 1460 g.
Connector Design and Wiring Configuration
Electrical connection 1 is a rectangular hybrid socket with 14 pins (13 occupied), using snap-locking mounting and a straight cable outlet. This connection follows the L5 connection diagram and is intended for the field device end. Electrical connection 2 is an open cable end with 12 wires (all occupied), designed for the control side. The connection patterns are specified as 00997533 for the input and 00997534 for the control side, ensuring accurate wiring during installation.
The hybrid design consolidates power and signal lines, reducing the number of separate cables required. This is particularly beneficial in robotic arms or moving gantries where space is limited and cable management is critical. The straight outlets on both ends simplify routing along linear axes.
Environmental and Compliance Considerations
The cable operates over a wide ambient temperature range: -40 °C to 90 °C for fixed installation and -25 °C to 80 °C for flexible use. This makes it suitable for applications in cold storage facilities or near heat-generating equipment. The degree of protection is IP20 when mounted, which is typical for cabinet or junction box connections.
Materials are RoHS-compliant and halogen-free, and the cable meets LABS (PWIS) conformity to VDMA24364 zone III, indicating low paint-wetting impairment. It also complies with EU RoHS and UK RoHS directives, as marked. The corrosion resistance class is 1 (low corrosion stress), making it appropriate for dry indoor environments.
Selection and Integration Value
When selecting this cable, engineers should verify that the L5 connection diagram matches the drive and motor pinouts, and that the 14-pin hybrid socket aligns with the mating connector on the field device. The open end on the control side allows custom termination, but the 12-wire configuration must be matched to the controller's I/O or communication ports.
For procurement teams, the cable's compliance with EN 61984 and its halogen-free, RoHS-compliant construction simplify regulatory approvals. The 10-meter length covers most robotic cell layouts, and the energy-chain suitability reduces downtime due to cable fatigue. By consolidating connections, this cable helps streamline assembly and maintenance, making it a practical choice for OEMs and system integrators building or retrofitting servo-driven automation.
