9571-20 Bently Nevada Interconnect Cable - Shielded 20ft

Product Overview

The Bently Nevada 9571-20 is a specialized Standard Interconnect Cable designed for critical machinery protection systems. This 20-foot cable features a two-conductor twisted, shielded 22 AWG construction to minimize electromagnetic interference (EMI). It is equipped with a two-socket moisture-resistant female connector at the sensor end and durable terminal lugs at the monitor end. The 9571-20 ensures the integrity of high-frequency vibration signals from transducers to proximity modules.

Global PLC Spare HUB's Insight

The 9571-20 is a critical link for Bently Nevada 3500 systems. The 22 AWG thickness provides the ideal balance between conduit flexibility and low signal resistance. Unlike generic cables, the 9571-20 features a moisture-resistant seal that prevents "wicking," which is essential for sensors mounted near cooling towers or steam turbines where humidity is high.

Target Equipment and Applications

• Proximitor Sensors: Compatible with 3300 XL series probes.
• Velocity Transducers: Reliable connection for vibration monitoring.
• Machinery Protection: Used with 3500/42M and 1900/65A monitors.
• Harsh Environments: High-durability insulation for oil, gas, and power industries.
• Diagnostic Capability: Supports clean transmission of Gap Voltage and Dynamic Waveforms.

Logistics and Protection

• Warranty: 12-Month Factory Warranty included.
• Express Delivery: Worldwide shipping via FedEx, UPS, and DHL.
• Packaging: Sealed in original Bently Nevada factory packaging.

Professional FAQ

Can I shorten the 9571-20 cable if the 20ft length is too long?
Yes, you can trim the monitor end. Ensure you maintain shield integrity and re-terminate the lugs properly to avoid noise interference.

Is the moisture-resistant connector submersible?
No, it is designed for high humidity and splashing. For underwater use, specialized waterproof housings are required.

How does 22 AWG conductor compare to 18 AWG?
The 22 AWG in the 9571-20 has lower capacitance per foot, which better preserves high-frequency vibration data over 20 feet.

What is the best practice for grounding the shield?
Ground the shield only at the monitor rack side using the 9571-20 terminal lugs to prevent ground loops.

Does this cable support 3300 XL transducers?
Yes, it is the standard interconnect for most Bently Nevada sensors requiring a 2-pin moisture-resistant socket.
