Overview and Key Specifications
The Festo NEBM-L10G14-EH-7.5-Q7N-LE12 (manufacturer ID 8181674) is a pre-assembled hybrid motor cable designed for connecting servo drives to motors in industrial automation systems. With a length of 7.5 meters and a shielded, halogen-free design, this cable supports reliable power and signal transmission in demanding environments.
Its construction includes four conductors of 0.75 mm², two of 0.5 mm², and six of 0.15 mm², with a nominal cross-section of 0.5 mm². The cable is rated for a current of 11.7 A at 40 °C and an operational voltage range of 0 to 48 V DC. It meets the requirements of EN 61984 and is CE and UKCA marked, complying with EU and UK RoHS directives.
Connector Design and Installation Flexibility
The cable features a rectangular hybrid socket on the field device end (connection 1) with a straight cable outlet and snap-locking mounting. This connector uses plug pattern L10 and has 14 pins, of which 13 are occupied. The control side (connection 2) is an open-ended cable with 12 wires, all occupied, and is inserted directly. Both ends are designed for straightforward installation, and the cable ends are fitted with ferrules for secure termination.
The cable is suitable for use in energy chains and robotic systems, offering a bending radius of 42 mm for fixed installation and 78.75 mm for flexible installation. The cable diameter is 10.5 mm ±0.3 mm, and the sheath is made of TPE-U(PUR) in gray, providing resistance to wear and environmental stress.
Environmental and Safety Compliance
This motor cable is built to operate in a wide range of conditions. It has an ambient temperature range of -40 °C to 90 °C for fixed installation and -25 °C to 80 °C for flexible use. The degree of protection is IP20 when mounted, and the cable is rated for overvoltage category I and contamination level 3, making it suitable for industrial control cabinets and similar environments.
The cable is halogen-free and RoHS-compliant, with a LABS (PWIS) conformity to VDMA24364 zone III, ensuring it meets strict material restrictions for use in painting and coating applications. Its corrosion resistance class is CRC 1, indicating low corrosion stress, which is typical for indoor, dry applications.
Selection and Integration Considerations
When selecting this cable, verify that the connector pattern and pin configuration match your drive and motor. The L10 plug pattern and the specific wiring diagram (connection patterns 00997533 and 00997534) are critical for proper integration. The cable is designed for use with Festo servo drives, but it can be adapted to other systems if the electrical characteristics and connector layout are compatible.
Consider the cable's bending radius and temperature limits when routing it in moving applications. For energy chains, ensure the bending radius is not less than 78.75 mm to maintain performance and longevity. The cable's weight of 1200 g should be accounted for in cable carrier designs.
Practical Benefits for Automation Systems
The NEBM-L10G14-EH-7.5-Q7N-LE12 simplifies installation by providing a ready-to-use, shielded cable with a hybrid connector that combines power and signal lines in one assembly. This reduces wiring time and potential points of failure. Its robust construction and compliance with international standards make it a dependable choice for OEMs and end users seeking to minimize downtime.
For procurement teams, the cable's clear specifications and certifications facilitate compliance with regulatory requirements. Its suitability for energy chains and robotic applications adds versatility, allowing standardization across multiple machine types.
