89477-80 Bently Nevada Interconnect Cable

89477-80 Bently Nevada Interconnect Cable

Product Introduction

The Bently Nevada 89477-80 interconnect cable provides a durable connection for vibration monitoring systems. This model uses two-conductor 18 AWG twisted and shielded wire. One end is equipped with a right-angle two-socket plug, which fits tight spaces easily. The opposite end features terminal lugs for secure field wiring. Additionally, the 80 ft length offers flexibility for remote sensor placement. Many plants choose this 89477-80 cable because it reduces noise and maintains signal integrity. You can rely on it for continuous machine protection.

Technical Specifications

Specifically, the 89477 series cable meets strict industrial requirements.

• Conductor: 18 AWG, twisted pair

• Shielding: Overall foil shield with drain wire

• Connector type (one end): Right-angle two-socket plug

• Connector type (other end): Terminal lugs (bare wire)

• Minimum length: 2.0 ft (0.6 m)

• Maximum length: 99 ft (30 m)

• Selected length: 80 ft (24.4 m)

• Insulation: PVC rated for oil and abrasion resistance

Furthermore, the shielding protects against electromagnetic interference (EMI). This feature is critical near motors or variable frequency drives. The right-angle plug also saves space in crowded junction boxes.

Mechanical & Environmental Ratings

First, the cable jacket withstands temperatures from -40°C to +105°C. Next, it resists common industrial fluids such as hydraulic oil and coolants. The bend radius is 10 times the outer diameter, which allows for flexible routing. Moreover, the terminal lugs accept screw or compression connections easily. The plug housing uses thermoplastic with high impact strength. Therefore, this Bently Nevada 89477-80 cable performs well in harsh environments like power plants and refineries.

Installation Guidelines

Before installation, always disconnect power to the monitoring system.

• Route the cable away from high-voltage lines to avoid noise coupling.

• Secure the right-angle plug by hand-tightening until it clicks.

• Crimp or solder terminal lugs onto the target terminals.

• Use the drain wire for grounding at the instrument side only.

• Avoid sharp bends near the plug end to prevent strain.

For instance, when mounting a proximity probe, leave a service loop of about 6 inches. This simplifies future maintenance. Additionally, label both ends of the 89477-80 for quick identification. Do not exceed the 99 ft maximum length, as signal strength may degrade. Finally, test continuity with a multimeter before powering up.

Frequently Asked Questions (FAQ)

1. Can I cut this 89477-80 cable to a shorter length?
Yes, you can shorten it. However, cutting voids the factory termination warranty. We recommend ordering the exact length you need, starting at 2 ft.

2. Is this cable compatible with older Bently Nevada monitors?
Absolutely. The 89477 series works with most 3300, 3500, and 7200 series monitoring systems. Double-check your monitor’s connector type before ordering.

3. Does the 80 ft length cause signal loss?
No. The 18 AWG twisted pair and shielding keep signal loss very low up to 99 ft. For runs over 50 ft, avoid parallel routing with power cables.

4. What is the difference between this model and a standard M8 cable?
This Bently Nevada 89477-80 uses a right-angle two-socket plug, not M8 threading. It also includes terminal lugs, which are easier for field wiring. Standard M8 cables have circular connectors on both ends.

5. How do I verify authenticity when the cable arrives?
Check the batch number printed on the cable jacket. Then compare the plug molding and wire color sequence to Bently Nevada drawings. We supply only new, original parts in factory packing.
