Product Description:
The B & R Automation’s CM16 Motor Cables are engineered for precision. The product 8ECF00X8.1251C-0 assures a reliable connection between the encoder and the switching unit. It enables encoder communication in motion control applications.
The 8ECF00X8.1251C-0 motor cable features dual 8-pin male Mini I/O connectors. It offers a secure interface for ACOPOS P3 drives. Its unified design supports both signal and power lines. The internal wiring uses tinned copper stranded conductors. Signal wires have a 4x 0.14 mm² core arrangement. Power lines have 4 x 0.35 mm² cross sections. Signal insulation is made of strong polyolefin foam. Supply wire insulation is built of a specific thermoplastic. Signal wires are identified by their hues of yellow, gray, pink and violet. Supply wires are marked in white/green, brown/green, blue and white. Copper and tin braiding is used throughout the shield and it provides more than 85% optical coverage. To defend against noise signal wires are stranded together and shielded with foil. The exterior diameter measures 6 mm ± 0.2 mm. The single bend radius is ≥19 mm while the moving bend radius surpasses 47 mm. The cable weighs around 0.3 kg. The operating voltage is rated at less than 30 V. It passes both the 1 kV wire-to-wire and the 0.5 kV wire-to-shield test. It can withstand more than 3,000,000 flex cycles at 20°C and has a bend radius of 78mm.
The CM16 Motor Cable 8ECF00X8.1251C-0 can function in temperatures ranging from -10 to 80 degrees Celsius. It can endure static temperatures ranging from -40°C to 80°C. Insulation resistance is rated at 200 MΩ·km. The cable length is 0.8 meters. It is intended for use in drag chains with accelerations up to 6 g. The velocity capability is up to 4 m/s. It satisfies CE and UKCA standards. The CM16 Motor Cable is designed for long-term performance.
Frequently Asked Questions about 8ECF00X8.1251C-0:
Q: Why is the shielding coverage over 85% important in 8ECF00X8.1251C-0?
A: Higher shielding coverage reduces electromagnetic interference in encoder signals. This ensures accurate data transmission in noisy industrial environments.
Q: How does the polyolefin foam insulation benefit the signal wires?
A: Polyolefin foam provides excellent electrical insulation with low dielectric constant. This reduces signal loss over short distances.
Q: Why are different color codes used for signal and supply wires in this cable?
A: Distinct color codes simplify the installation and troubleshooting process. They help ensure correct wire identification during integration.
Q: How does the special thermoplastic insulation support supply wires in 8ECF00X8.1251C-0?
A: It provides thermal and mechanical resistance in moving systems. This minimizes wear during repeated flexing in drag chain applications.
Q: What’s the significance of the 1x (4x 0.14 mm²) + 4x 0.35 mm² structure in 8ECF00X8.1251C-0?
A: This structure separates signal and power lines clearly within one cable. It maintains electrical performance while simplifying cable routing.
