106765-07 3500 Series Interconnect Cable | Bently Nevada

Product Overview

The Bently Nevada 106765-07 serves as a specialized 7-meter Interconnect Cable designed for the 3500 Series Machinery Protection System. This cable establishes a secure, high-integrity data link between the monitoring rack backplane and external termination blocks or communication gateways. We provide this unit as 100% Brand New Original equipment, manufactured in the U.S.A., to ensure the lossless transmission of safety-critical vibration and position signals.

Part Number Breakdown

Bently Nevada utilizes the suffix of the 106765 series to define specific cable lengths for various cabinet architectures:

Technical Specifications

The 106765-07 features industrial-grade shielding and high-conductivity conductors to maintain signal purity over its 7-meter span:

Engineering Advantages

• Superior EMI Rejection: The 106765-07 incorporates high-density foil and braided shielding. This construction blocks electromagnetic interference (EMI) from adjacent high-voltage power lines and variable frequency drives (VFDs), preventing noise injection into sensitive 4-20mA or buffered transducer signals.

• Low-Capacitance Design: Bently Nevada engineers this cable to minimize signal attenuation. By maintaining low capacitance per metre, the cable preserves the sharp rise-times required for high-frequency vibration data and Keyphasor* pulses, even at the full 7-metre length.

• Industrial Durability: The heavy-duty outer jacket resists chemical exposure and abrasion. This makes it suitable for routing through cable trays in harsh refinery or power plant environments where oil and moisture are common.

• Precision Connectors: The cable features factory-molded, high-reliability connectors. These ensure a vibration-proof mechanical lock with the 3500 rack backplane, eliminating the risk of intermittent signal loss that often occurs with field-crimped alternatives.

• Optimized Flex Radius: Despite its robust shielding, the cable maintains sufficient flexibility for routing through tight conduits and narrow cabinet side-panels, simplifying the installation of complex machinery protection racks.

FAQs

• Can I use the 106765-07 with any 3500 Series Monitor?

  Yes. The 106765-07 functions as a universal interconnect for the 3500 system, typically linking the main rack to External Termination (ET) blocks or the 3500/92 Communication Gateway. Always verify your specific termination panel pin-mapping in the manual.

• Why should I choose the 7-metre version over shorter cables?

  The 7-metre length provides the necessary slack for routing through overhead trays or sub-floor channels in multi-cabinet control rooms. It allows for clean wire management without putting physical stress on the backplane connectors.

• How do I verify the integrity of this cable after installation?

  We recommend performing a loop-check using a signal simulator. Because we supply this cable as 100% Brand New Original, it will meet the factory impedance and continuity specifications required for SIL-rated safety loops.

• Does the 106765-07 require any special grounding?

  The cable shielding grounds automatically through the 3500 rack interface. Ensure your rack chassis connects to a high-quality instrument ground to maximize the cable’s noise-rejection performance.
