Purpose-Built Connection for EMMT-ST and CMMT-ST
The Festo NEBM-M17G12-EH-5-Q6N-LE12 motor cable (manufacturer ID 8181668) is a shielded hybrid cable engineered to link the EMMT-ST stepper motor with the CMMT-ST servo drive. It consolidates power and feedback signals into a single 12-pin M17x0.75 round connector at the field device end, while the control side terminates in an open end with cable end sleeves. This design simplifies wiring and reduces the number of separate cables required in a motion control system.
The cable is rated for a DC operating voltage range of 0 to 48 V and a current of 7.6 A at 40 °C, with a surge resistance of 1.5 kV. It meets EN 61984 and is CE and UKCA marked according to EU and UK RoHS directives. The cable is halogen-free, RoHS-compliant, and conforms to VDMA24364 zone III for LABS (PWIS) requirements, making it suitable for use in paint shops and other sensitive manufacturing environments.
Energy Chain Compatibility and Flexibility
This cable is explicitly designed for energy chain applications, allowing continuous movement without compromising signal integrity. The cable construction includes 4 x 0.5 mm² plus 2 x 0.5 mm² plus 6 x 0.15 mm² conductors, with a nominal cross-section of 0.5 mm². The outer sheath is made of TPE-U (PUR) in gray, providing abrasion resistance and flexibility.
For fixed installations, the minimum bending radius is 42 mm, while for flexible installations it is 78.75 mm. The cable diameter is 10.5 mm ± 0.3 mm. It supports a wide ambient temperature range: -40 °C to 90 °C for fixed use and -25 °C to 80 °C for flexible use. This makes the cable adaptable to both stationary machinery and dynamic robotic or handling systems.
Shielding and Environmental Protection
The integrated shield provides protection against electromagnetic interference, which is critical for maintaining stable communication between the drive and motor in industrial settings with high electrical noise. The cable achieves IP67 protection when the connector is properly mounted, ensuring resistance to dust and water ingress. The screw-type locking mechanism on the M17 connector secures the connection against vibration and accidental disconnection.
The cable is rated for overvoltage category I and contamination level 3, reflecting its suitability for industrial environments. Its corrosion resistance class is 1 (low corrosion stress), which is typical for indoor automation applications.
Selection and Integration Considerations
When integrating this cable, verify that your application requires a 5-meter length and that the straight connector orientation fits your layout. The cable is available with a straight outlet on both ends, which is ideal for linear routing. The open end on the control side allows for custom termination inside the control cabinet, but ensure that the wire ends (cable end sleeves) are properly crimped to maintain reliable connections.
Because the cable is halogen-free and LABS-compliant, it is a safe choice for food processing, electronics assembly, and automotive paint lines. The product weight of 730 g should be considered when calculating moving loads in energy chains.
Practical Benefits for System Builders
Using a pre-engineered cable like the NEBM-M17G12-EH-5-Q6N-LE12 reduces design time and eliminates the risk of mismatched connectors. The hybrid design minimizes cabinet space and simplifies troubleshooting, as only one cable carries both power and feedback. The robust shielding and energy chain suitability contribute to longer service life and reduced downtime in high-cycle applications.
For procurement teams, this cable is a genuine Festo part with a clear manufacturer ID, ensuring traceability and consistent quality. Its compliance with international standards simplifies global machine builds.
