Overview and Design
The Festo NEBM-M17G12-EH-2.5-Q7N-LE12 motor cable (manufacturer ID 8195458) is a hybrid connection solution engineered for servo drive applications. It combines power and signal lines in a single round, shielded cable, simplifying wiring in compact automation systems. The cable is designed to meet EN 61984, ensuring reliable electrical performance in industrial environments.
The cable features a 12-pin M17x0.75 hybrid socket on the field device end with a straight cable outlet and screw-type locking. The control side terminates in an open end with 12 wires, each fitted with cable end sleeves for straightforward integration into terminal blocks. With a cable length of 2.5 m and a diameter of 10.5 mm (±0.3 mm), it offers a practical reach for typical machine layouts.
Electrical and Environmental Specifications
Rated for a DC operating voltage range of 0 to 48 V and a current rating of 11.7 A at 40°C, this cable supports moderate power and signal transmission. It has a surge resistance of 1.5 kV and an overvoltage category of I, providing adequate protection for standard servo drive circuits. The cable is shielded, which helps minimize electromagnetic interference in noisy industrial settings.
The cable is designed for a wide ambient temperature range: -40°C to 90°C for fixed installation and -25°C to 80°C for flexible use. Its degree of protection is IP67 when mounted, making it suitable for environments where dust and water ingress are a concern. The cable sheath is made of TPE-U (PUR), a halogen-free material that is RoHS-compliant and meets LABS (PWIS) conformity per VDMA24364 zone III, ensuring compatibility with paint shops and other sensitive processes.
Mechanical Flexibility and Installation
This cable is suitable for energy chains, offering a bending radius of 42 mm for fixed installation and 78.75 mm for flexible routing. This flexibility allows for dynamic applications where the cable must withstand repeated movement without failure. The cable design includes 4 x 0.75 mm² power conductors, 2 x 0.5 mm² conductors, and 6 x 0.15 mm² signal wires, providing a balanced combination of power and signal capacity.
Installation is simplified by the cable designation without a label holder, reducing clutter and potential confusion. The screw-type lock on the field device end ensures a secure connection, while the open-end control side allows for custom termination. The cable's round design and straight outlets facilitate routing in cable trays and conduits.
Compliance and Quality Assurance
The NEBM-M17G12-EH-2.5-Q7N-LE12 complies with CE marking under the EU RoHS directive and UKCA marking under UK RoHS instructions, confirming its adherence to environmental and safety standards. The cable is halogen-free and RoHS-compliant, supporting sustainability goals. Its corrosion resistance class is 1 (low corrosion stress), making it suitable for typical industrial environments without aggressive chemicals.
With a product weight of 400 g, the cable is robust yet manageable. The connector test conditions are available on request, allowing for verification of performance in specific applications. The cable's contamination level is 3, indicating it can operate in environments with moderate levels of pollutants.
Application Considerations
When selecting this cable, consider the operating voltage and current requirements of your servo drive system. The 48 V DC rating is appropriate for many low-voltage servo applications, but verify that your system does not exceed this limit. The IP67 rating is only guaranteed when the connector is properly mounted, so ensure correct installation to maintain protection.
For dynamic applications, the flexible bending radius of 78.75 mm must be respected to prevent cable damage. The cable's suitability for energy chains makes it a viable option for robotic or pick-and-place systems. The open-end design on the control side offers flexibility in wiring, but it requires careful termination to maintain signal integrity.
Overall, the Festo NEBM-M17G12-EH-2.5-Q7N-LE12 provides a reliable, compliant, and mechanically robust solution for connecting servo drives to field devices, balancing performance with ease of integration.
