Application-Specific Motor Cable for Servo Drive Integration
The Festo NEBM-M23G15-EH-5-Q9N-S1LEG21 (part number 8190888) is a pre-assembled hybrid motor cable engineered for demanding servo drive applications. It combines power and signal lines in a single shielded cable, simplifying wiring and reducing installation time. With a 5-meter length and a straight M23x1 hybrid socket on the field device end, it connects directly to compatible motors. The control side terminates in a Sub-D connector with an open end, offering flexibility for integration into various drive controllers. This cable is designed to meet the requirements of modern automation systems, including compatibility with the innovative Multi-Carrier System MCS developed by Festo and Siemens.
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 overvoltage category III and has a surge resistance of 6 kV, ensuring robust performance in industrial power environments. The cable features 15 pins on the M23 connector, with 12 occupied, and 21 wires on the control side, also with 12 occupied. The conductor design is 4 x 1.5 mm² plus one pair of 0.75 mm² and additional signal pairs, providing ample capacity for power and feedback signals. The cable is shielded, which is critical for electromagnetic compatibility in noisy industrial settings.
Mechanical Durability
Mechanically, the cable is built for longevity. It has a cable diameter of 12.8 mm (±0.3 mm) and a minimum bending radius of 51.2 mm for fixed installation and 96 mm for flexible use. The cable is suitable for energy chains, making it ideal for moving applications such as robotic arms or linear axes. The sheath is made of halogen-free TPE-U(PUR), offering resistance to abrasion and environmental stress. The cable can operate in ambient temperatures from -40°C to 90°C for fixed installation and -25°C to 80°C for flexible routing, covering a wide range of industrial conditions.
Standards Compliance and Environmental Suitability
This motor cable is designed in accordance with EN 61984, ensuring it meets safety and performance standards for connectors and cable assemblies. It carries CE and UKCA markings, complying with the EU Low Voltage and RoHS directives, as well as UK equivalents. The cable is also LABS (PWIS) conformant to VDMA24364-B2-L, which is essential for use in paint shops and other applications where silicone-free materials are required. The degree of protection is IP20 for the open end and IP67 for the mounted M23 connector, providing dust-tight and water-resistant performance when properly installed. The materials are RoHS-compliant and halogen-free, supporting environmental and safety goals.
Selection and Integration Considerations
When selecting this cable, engineers should verify that the connector pattern matches the motor and drive controller. The field device end uses connection pattern 00995912, while the control side uses 00995641, which must align with the respective equipment. The cable's weight of 1150 g and its flexible design should be factored into cable management and energy chain sizing. The cable is rated for corrosion resistance class 1 (low corrosion stress), making it suitable for typical industrial environments without aggressive chemicals. For applications requiring high flexibility and continuous motion, the cable's energy chain suitability and bending radius specifications are critical. Always confirm that the operating voltage, current, and pin assignments are compatible with your specific motor and drive system.
