Overview and Key Specifications
The Festo NEBM-L5G14-EH-2.5-Q6N-LE12 (manufacturer ID 8181675) is a pre-assembled hybrid motor cable designed for connecting servo drives to motors in automation systems. It features a 14-pin hybrid socket on the field device end and an open cable end with 12 wires on the control side, supporting both power and signal transmission in a single cable. The cable is 2.5 m long, has a diameter of 10.5 mm (±0.3 mm), and weighs 365 g. It is rated for a DC operating voltage range of 0 to 48 V and a current rating of 7.6 A at 40 °C, with a surge resistance of 1.5 kV. The cable is shielded and complies with EN 61984, making it suitable for industrial environments requiring reliable electrical performance.
Mechanical and Environmental Suitability
This cable is engineered for demanding motion applications, particularly robotics and energy chain systems. It offers a bending radius of 42 mm for fixed installation and 78.75 mm for flexible (moving) cable installation, allowing it to withstand repeated flexing without compromising performance. The cable sheath is made of TPE-U(PUR) with a PP insulating sheath, providing durability and resistance to wear. The cable is halogen-free and RoHS-compliant, and it meets LABS (PWIS) conformity to VDMA24364 zone III, which is important for paint shop applications. The ambient temperature range is -40 °C to 90 °C for fixed installation and -25 °C to 80 °C for flexible use, ensuring operation in a variety of industrial conditions. The degree of protection is IP20 in the mounted state, suitable for control cabinet environments.
Connection and Wiring Details
The field device end uses a rectangular hybrid socket with a straight cable outlet and snap-locking mounting. It has 14 pins, of which 13 are occupied, following connection diagram L5 (pattern 00997533). The control side is an open end with 12 wires, all occupied, using connection pattern 00997534. The cable design includes 4 x 0.5 mm² + 2 x 0.5 mm² + 6 x 0.15 mm² conductors, with wire ends terminated with cable end sleeves for secure connections. This configuration supports hybrid power and signal transmission, reducing cabling complexity in servo drive systems.
Selection and Integration Considerations
When integrating this cable, verify that the connector type and pin assignment match your drive and motor. The hybrid socket is designed for Festo servo drives, but always cross-check the connection diagrams (00997533 and 00997534) against your equipment documentation. The cable is suitable for energy chains, but ensure the bending radius and cable diameter are compatible with your chain dimensions. The overvoltage category is I, and the contamination level is 3, so it is intended for indoor, controlled environments. The corrosion resistance class is 1 (low corrosion stress), meaning it is not suitable for harsh chemical exposure. For applications requiring high flexibility, note the reduced ambient temperature range for flexible installation.
Compliance and Quality Assurance
The NEBM-L5G14-EH-2.5-Q6N-LE12 carries CE marking as per EU RoHS directive and UKCA marking to UK RoHS instructions, ensuring compliance with current regulations. It is halogen-free and RoHS-compliant, supporting sustainability goals. The cable is tested under conditions on request, so for critical applications, request specific test data from Festo to validate performance. The product weight and dimensions are provided for mechanical design, but always confirm physical fit with your system layout.
