Overview and Key Specifications
The Festo NEBM-M17G12-EH-7.5-Q6N-LE12 (part number 8190096) is a 7.5-meter hybrid motor cable designed for connecting servo drives to motors in energy chain applications. It features a 12-pin M17x0.75 hybrid socket on the field device end and an open end on the control side, with a straight cable outlet on both ends. The cable is rated for a current of 7.6 A at 40°C and a DC operating voltage range of 0 to 48 V, making it suitable for low-voltage servo systems. Its robust construction includes a shielded design and a TPE-U(PUR) sheath, providing durability and protection in demanding industrial environments.
Mechanical and Environmental Suitability
This cable is engineered for reliable performance in motion control applications where cables must withstand continuous flexing. It is explicitly designed for use in energy chains, with a minimum bending radius of 78.75 mm for flexible installation and 42 mm for fixed installation. 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 operating temperature range is -40°C to 90°C for fixed installation and -25°C to 80°C for flexible installation, allowing deployment in a wide range of thermal environments. The cable sheath is gray, halogen-free, and RoHS-compliant, with a corrosion resistance class of 1 (low corrosion stress).
Electrical Performance and Protection
The NEBM-M17G12-EH-7.5-Q6N-LE12 provides stable electrical performance with a surge resistance of 1.5 kV and overvoltage category I. The integrated shield ensures immunity to electromagnetic interference, which is critical for maintaining signal integrity in servo drive systems. The cable meets the requirements of EN 61984 and is rated IP67 when mounted, offering protection against dust and water ingress. The connector uses a screw-type lock for secure mounting, and the connection pattern is specified as 00997531 on the field device end and 00997532 on the control side, ensuring correct wiring in compatible Festo systems.
Compliance and Material Quality
This cable is designed with attention to regulatory and industry standards. It carries CE marking as per the EU RoHS directive and UKCA marking to UK RoHS instructions, confirming compliance with hazardous substance restrictions. The product also conforms to VDMA24364 zone III for LABS (PWIS) conformity, making it suitable for use in paint and coating applications where silicone-free materials are required. The insulating sheath material is polypropylene (PP), and the cable is halogen-free, reducing environmental impact and improving safety in case of fire. The product weight is 1095 g, and the cable designation is without label holder, simplifying installation in tight spaces.
Integration and Application Considerations
When integrating this motor cable into a servo drive system, engineers should verify compatibility with the drive and motor connectors, as the M17x0.75 hybrid socket is specific to certain Festo components. The open end on the control side allows for custom termination, but the connection pattern must match the drive's pinout. The cable's suitability for energy chains makes it ideal for automated machinery, robotics, and material handling equipment where cables are subject to repeated bending. The IP67 rating (in mounted state) ensures reliable operation in environments with dust or occasional water exposure. For procurement teams, the cable's compliance with EN 61984 and RoHS directives simplifies regulatory approval, while its durable construction reduces downtime and maintenance costs over the system's lifecycle.
