Product Description:

B&R 8BCH0005.1111A-0 Motor Cable has an optimized supply and signal wire configuration that incorporates two 0.30 mm2 and four 0.15 mm2 conductors whose resistance is 26 ohms that facilitates reliable operation and minimal power losses as well as flexible data transmission in automation systems in industry.

The 8BCH0005.1111A-0 motor cable is constructed with internal support materials (known as filler elements) that help maintain the cable’s shape and balance during movement and its insulation around the conductors must maintain a minimum resistance of 200 MΩ per kilometer. It can operate effectively at speeds of up to 300 m/min which makes it applicable in rapid movements and its wires that carry the power have a low resistance capable up to 13.3 ohms which guarantees improved conductivity and lowering energy lost in the process. To ensure stable signal transmission, the signal cables are enclosed in both a metallic braid and a thin shielding film and this braid is made from tinned copper and covers more than 85% of the cable surface which significantly limits the impact of electrical noise or radio frequency interference on signal quality.

This CM16 series cable can endure over three million continuous bending cycles without compromising performance which is vital in machinery that experiences constant motion or vibration and it is wrapped in a braided mesh of tinned copper that overlaps extensively (over 85% coverage), paired with a foil barrier. It utilizes numerous fine strands of copper, clad in a protective layer of tin, rather than solid metal conductors, which increases flexibility and resistance to oxidation and the overall diameter of the cable is about 13 mm with a small allowance (0.4 mm) concerning deviations.

Frequently Asked Questions about 8BCH0005.1111A-0:

Q: Why does the 8BCH0005.1111A-0 cable use tinned copper instead of bare copper conductors?

A: Tinned copper resists oxidation better than bare copper, especially in humid or high-vibration environments. This improves longevity and ensures consistent conductivity in industrial setups.

Q: How does the cable’s shielding improve signal reliability in noisy environments?

A: The dual-layer shielding minimizes external electromagnetic interference, which is common near motors or high-frequency devices. This ensures data integrity and reduces signal distortion.

Q: Why is the conductor resistance for supply lines in the 8BCH0005.1111A-0 limited to 26 ohms/km?

A: This resistance ensures efficient voltage delivery for auxiliary functions without generating excessive heat. It supports stable power transmission across short to mid-range distances.

Q: What is the benefit of having both 0.30 mm² and 0.15 mm² signal wires in one cable?

A: Using multiple gauges allows flexible routing of high- and low-priority signals. It simplifies wiring and minimizes the need for additional cables.

Q: How does the ≥3 million flex cycle rating benefit robotic or moving machinery applications?

A: It enables the cable to perform reliably under constant motion, avoiding breakage or fatigue. This is essential for cable carriers or articulated robotic arms.
