Allen-Bradley 2090-CFBM7DF-CEAA01 SpeedTEC Resolver Cable

Allen-Bradley 2090-CFBM7DF-CEAA01 SIN/COS High-Resolution Encoder Cable

The Allen-Bradley 2090-CFBM7DF-CEAA01 is a short-length feedback cable designed for high-precision encoders. It transmits sensitive SIN/COS or Resolver signals for ultra-accurate motor position control.

Technical Specifications

• Manufacturer & Model: Allen-Bradley | 2090-CFBM7DF-CEAA01
• Product Series: Bulletin 2090 SpeedTEC
• Cable Function: Motor Feedback Only
• Encoder Type: SIN/COS High-Resolution & Resolver
• Cable Length: 1 Meter
• Flex Type: Standard (Non-Flex) for fixed installations
• Conductor: Fine multi-strand wire for high-frequency signal integrity
• Shielding: Comprehensive foil and braid shield for protection against electromagnetic interference (EMI)
• Impedance: Matched for high-resolution analog signals (typically 100-120Ω)
• Motor End Connector: SpeedTec DIN Connector
• Drive End Connection: Flying-lead (individual, color-coded wires for precise termination)

Installation & Wiring

• Plug the SpeedTec DIN connector firmly into the high-resolution encoder on the motor.
• Route the 1-meter cable neatly, keeping it away from power lines to prevent signal noise.
• Carefully terminate each color-coded flying lead to the designated SIN, COS, and reference terminals on the 2090-series drive.
• Ensure the cable shield is properly grounded at the drive end to maintain signal purity.
• This standard-flex cable is ideal for short, fixed connections inside control panels or motor enclosures.

Packaging & Shipping

• Includes one Allen-Bradley 2090-CFBM7DF-CEAA01 1-meter high-resolution feedback cable.
• Individually packaged to prevent connector damage.
• We ship worldwide via FedEx, UPS, or DHL with tracking provided.

Frequently Asked Questions (FAQ)

• What type of encoder is this cable for? It is specifically for SIN/COS (sine/cosine) high-resolution encoders and Resolver-type feedback devices.
• What is the length of this cable? It is 1 meter (approximately 3.3 feet) long.
• Can it be used in a cable carrier? No, its "Standard (Non-Flex)" rating means it is not designed for continuous bending in cable tracks.
• What's the difference between this and an incremental encoder cable? This cable carries analog SIN/COS signals for very high positioning resolution, not digital pulse (A/B/Z) signals.
• Why is shielding so important for this cable? SIN/COS signals are low-voltage analog signals highly susceptible to electrical noise; robust shielding is critical for accuracy.
