8BCF0003.1221B-0
The B & R Automation 8BCF0003.1221B-0 motor cable is a precision-engineered component in the CM16 Motor Cables series designed for industrial automation power and signal distribution. Manufactured by B & R Automation, this 12 VDC-rated cable delivers reliable low-power performance with a rated power of 1.92 W to support servo feedback loops and encoder signaling integrity. Its integrated fan assembly, rotating at 3250 RPM, ensures continuous airflow to prevent local heat buildup in compact enclosures. The cable’s robust design maintains signal fidelity under demanding conditions while minimizing thermal load on controller outputs. With its compact form factor and consistent performance, the 8BCF0003.1221B-0 is ideal for machine controls where space and reliability are paramount.
Detailed technical specifications define the operational envelope of this cable assembly. The frame measures 80 x 80 x 25 mm for compatibility with standard panel cutouts, while a 3-pin connector secures reliable mating without misalignment. It operates at 12V DC with a rated current of 0.16 A, ensuring minimal power draw. The cable sustains a static pressure of 0.19 inH₂O to overcome enclosure back-pressure and delivers an air flow of 45.8 CFM for efficient cooling. Its ingress protection rating of IP20 guards against solid particle ingress, and the bearing type is a Ball Bearing for low friction rotation. The material construction uses durable plastic for both frame and impeller, balancing weight and cost. The noise level is limited to 33 dB(A), preserving comfortable ambient conditions for operators.
Operational performance emphasizes continuous duty capability and environmental resilience. The integrated fan assembly delivers consistent 45.8 CFM airflow at 3250 RPM, preventing component overheating even under sustained loads. Static back-pressure resistance of 0.19 inH₂O ensures reliable ventilation in compact or obstructed enclosures. Temperature resilience spans from -10°C to +70°C, supporting chilled and heated spaces without degradation. Ball bearing construction reduces wear over extended duty cycles, enhancing service life. With low acoustic emissions of 33 dB(A), this cable maintains a quiet operating profile critical for control cabinets in production environments.
System integration is simplified through the standardized 3-pin connector, which provides secure power and ground paths for both drive and fan circuits. The PUR jacket offers chemical and oil resistance typical in industrial automation settings. An embedded braided shield (≥85% coverage) ensures electromagnetic compatibility, preserving encoder and feedback signal integrity. This motor cable is targeted at industrial machine control panels, servo drive systems, and factory automation applications where consistent cooling, compact installation, and reliable power delivery are required.
