Application-Specific Motor Cable for Servo Drive Integration
The Festo NEBM-M23G15-EH-10-Q9N-S1LEG21 (manufacturer ID 8190890) is a pre-assembled hybrid motor cable engineered for connecting servo drives to motors and encoders in field device installations. Its 10-meter length and straight M23x1 hybrid socket on the field device end, paired with a control-side cable terminated in Sub-D and open ends, make it a ready-to-use solution for cabinets and machine wiring. The cable is designed for high-performance applications where signal integrity and power delivery must coexist in a single, shielded assembly.
Electrical and Mechanical Specifications
The cable supports a DC operating voltage range of 0 to 850 V and an AC range of 0 to 630 V, with a current rating of 17.8 A at 40 °C. It is rated for surge resistance up to 6 kV and complies with overvoltage category III, making it suitable for industrial power circuits. The 15-pin M23 connector uses 12 occupied pins, while the control-side Sub-D and open-end connection also uses 12 of its 21 available wires. The cable construction includes 4 x 1.5 mm² power conductors plus signal pairs (2 x 0.75 mm² and 2 x 0.24 mm² + 2 x 2 x 0.15 mm²), with a nominal cross-section of 0.75 mm². The cable sheath is made of halogen-free TPE-U (PUR) in gray, with a diameter of 12.8 mm ± 0.3 mm.
Robustness and Environmental Suitability
This cable is built for demanding industrial environments. It is shielded, providing protection against electromagnetic interference, and is suitable for energy chains, with a bending radius of 96 mm for flexible installation and 51.2 mm for fixed installation. The operating temperature range is -40 °C to 90 °C for fixed installation and -25 °C to 80 °C for flexible use. The connector achieves IP20 and IP67 protection when mounted, and the cable is rated for contamination level 3 and corrosion resistance class 1 (low corrosion stress). It is also LABS (PWIS) conformant to VDMA24364-B2-L, making it suitable for use in paint shops and other sensitive manufacturing areas.
Standards Compliance and Material Quality
The cable is designed in accordance with EN 61984, ensuring reliable electrical connections for field devices. It carries CE marking per the EU Low Voltage and RoHS directives, and UKCA marking per UK RoHS and electrical equipment regulations. The materials are RoHS-compliant and halogen-free, with a cable sheath of TPE-U (PUR) and insulating sheath of PP. The product weight is approximately 2300 g, reflecting a substantial build that resists wear and tear. These attributes make the cable a dependable choice for engineers and procurement teams specifying components for automation systems that require long service life and consistent performance.
Selection and Integration Considerations
When integrating this cable, verify that the M23x1 snap-locking connector matches your motor's field device interface and that the control-side Sub-D and open-end wiring aligns with your drive's pinout. The cable is designed for use with Festo servo drives, but its hybrid design (power and signal in one cable) simplifies routing and reduces installation time. The 10-meter length offers flexibility in machine layout, while the straight cable outlets on both ends facilitate clean routing in cable carriers. For procurement, note that the cable is supplied with cable end sleeves on wire ends, and test conditions for the connector are available on request. This product is a practical choice for new installations or retrofits where a robust, shielded, and standards-compliant motor cable is required.
