Application-Specific Motor Cable for Stepper-to-Servo Connections
The Festo NEBM-M17G12-EH-5-Q7N-LE12 (part no. 8195459) is a 5-meter hybrid motor cable engineered to link stepper motors with servo drives. Its primary role is to transmit both power and feedback signals in a single, shielded assembly, which simplifies wiring in compact machine designs. The cable is designed for reliable performance in demanding industrial settings, offering a wide operating temperature range and robust construction suitable for continuous use.
Technical Specifications and Integration Details
This cable features a round M17x0.75 hybrid socket on the field device end with 12 occupied pins, and an open-end cable on the control side, also with 12 wires. The connection patterns are defined as 00997531 (field device) and 00997532 (control side), ensuring correct pinout for compatible Festo drives and motors. The cable supports DC operating voltages from 0 to 48 V and carries a current rating of 11.7 A at 40°C, with a surge resistance of 1.5 kV. It is shielded, which is critical for minimizing electromagnetic interference in servo systems.
The cable is designed for both fixed and flexible installation. For fixed routing, the minimum bending radius is 42 mm; for flexible applications, it is 78.75 mm. The cable diameter is 10.5 mm (±0.3 mm), and the conductor configuration is 4 x 0.75 mm² + 2 x 0.5 mm² + 6 x 0.15 mm², with wire ends terminated with cable end sleeves. The cable sheath is made of TPE-U (PUR) in gray, and the insulating sheath is PP. It is halogen-free and RoHS-compliant, meeting EU and UK RoHS directives.
Environmental and Mechanical Durability
The NEBM-M17G12-EH-5-Q7N-LE12 is built to withstand harsh conditions. It operates in ambient temperatures from -40°C to 90°C for fixed installation, and from -25°C to 80°C for flexible use. The cable is suitable for energy chains, making it a practical choice for moving axes in automation equipment. Its degree of protection is IP67 when mounted, providing resistance to dust and water ingress. The cable also meets LABS (PWIS) conformity per VDMA24364 zone III, which is important for paint shop applications.
Selection and Compliance Considerations
When integrating this cable, verify that the pin assignments and connection patterns match your drive and motor specifications. The cable is designed as a functional replacement for other electrical interfaces, but always confirm compatibility with your specific Festo components. The product weight is 800 g, which is relevant for cable management in moving applications. The cable is rated for overvoltage category I and contamination level 3, and its corrosion resistance class is 1 (low corrosion stress).
For procurement, note that the cable is based on EN 61984 and is CE and UKCA marked. It is halogen-free and RoHS-compliant, aligning with modern environmental standards. The cable designation is 'Without label holder', so plan for your own labeling if needed.
Practical Value in Automation Systems
This motor cable simplifies the connection between stepper motors and servo drives, reducing wiring complexity and potential error points. Its shielded design and robust materials contribute to signal integrity and long service life, even in high-flex applications. The wide temperature range and IP67 rating make it suitable for a variety of industrial environments, from standard factory floors to more demanding settings. By using a single hybrid cable for power and signals, you can streamline machine assembly and maintenance, ultimately improving system reliability and uptime.
