Product Description:
B&R 8BCR0002.1121A-0 Motor Cable includes six units, each featuring a 12-pin female 615-series connector, designed for reliable, compact signal or low voltage power transmission in industrial automation systems.
The 8BCR0002.1121A-0 motor cable conforms to rigorous German testing procedures (VDE 0472 Part 803) which suggests it is specifically constructed to withstand degradation when exposed to petroleum-based substances and industrial lubricants. Every internal conductor is encased in a specially designed plastic compound that offers a high degree of toughness, flexibility and protection. It is rated to endure over three million cycles of repeated bending or motion which makes it ideal for continuous-flex applications such as cable carriers or dynamic robotics without loss of performance. This unit meets both American (UL) and Canadian (CSA) standards for appliance wiring material and it adheres to UL AWM Style 20671 and CSA AWM ratings which confirms its ability to safely operate at temperatures up to 90°C and voltages up to 30 volts. Its plug and socket components are rated for fewer than 500 connection and disconnection events, which is adequate for semi-permanent installations but not suited for frequent mating cycles.
This 8B0C0320HW00.B00-1 power supply internal wiring is arranged in three twisted pairs and each of these pairs is individually wrapped in metallic foil to minimize electromagnetic interference which ensures signal integrity in noisy electrical environments. This module insulation system is designed to handle up to 1,500 volts of electrical pressure between individual wires which provides protection against voltage spikes and breakdowns in industrial settings. It includes six wires in total, arranged as three groups of two and the conductor sizes used are a mix of 24 gauge and 19 gauge wires.
Frequently Asked Questions about 8BCR0002.1121A-0:
Q: Why does the 8BCR0002.1121A-0 cable use tinned copper instead of bare copper conductors?
A: Tinned copper improves corrosion resistance and enhances solderability, especially in harsh environments. It also extends conductor life in high-moisture or oil-exposed industrial settings.
Q: How does foil shielding in this cable reduce electromagnetic interference?
A: The metallic foil around each twisted pair blocks external noise from disrupting signals. This ensures cleaner, uninterrupted communication in environments with variable-frequency drives or heavy machinery.
Q: What role does ≥90% copper braiding play in the 8BCR0002.1121A-0 cable’s performance?
A: High optical coverage offers exceptional EMI suppression and mechanical reinforcement. It adds durability while preserving data integrity in electrically noisy settings.
Q: Why are twisted pairs used in the CM16 series motor cable design?
A: Twisting helps cancel out electromagnetic fields generated by the current. This technique stabilizes signal quality over long runs and in dynamic applications.
Q: Is the 8BCR0002.1121A-0 cable suitable for vertical cable carriers?
A: Yes, thanks to its flexible thermoplastic insulation and high flex rating. It performs reliably in both horizontal and vertical dynamic installations.
