Bently Nevada CB2W100-015 – Dual-Wire Interconnect Cable | 3500 Series Proximity Transducer System
Engineering Background: The Bently Nevada 3500 Series machinery protection system is the global standard for continuous vibration monitoring in rotating equipment. The interconnect cable is the critical signal path between the proximity transducer and the monitor rack — any compromise in cable integrity directly impacts measurement accuracy and system reliability.
Product Positioning: The CB2W100-015 is a factory-specified, dual-wire coaxial interconnect cable engineered for use within Bently Nevada 3500 proximity transducer assemblies. It maintains signal fidelity across the full operating range and is designed for permanent installation in harsh industrial environments. Konmask.com supplies this cable as an OEM-equivalent replacement component, verified against original Bently Nevada specifications.

- Plug-and-play replacement: Identical form, fit, and function to the original Bently Nevada cable — no field modification required.
System Architecture & Signal Flow
In a standard Bently Nevada 3500 proximity system, the signal chain is:
Proximity Probe → Extension Cable → CB2W100-015 Interconnect Cable → 3500/40M or 3500/42M Monitor Module → 3500 Rack
The CB2W100-015 occupies the final interconnect segment between the field-side extension cable and the monitor rack input. Its low-loss, shielded construction ensures that the –24 VDC bias voltage and the AC vibration signal are transmitted without attenuation or noise injection, preserving the ±200 mV/mil (±7.87 V/mm) sensitivity standard of the 3500 system.

Technical FAQ
Q: Is CB2W100-015 compatible with 3300 Series monitors?
A: No. The CB2W100-015 is specified for the 3500 Series. For 3300 Series applications, a different interconnect cable part number is required — contact us for cross-reference assistance.
Q: Can this cable be used in hazardous (Ex) areas?
A: The standard CB2W100-015 is not ATEX/IECEx certified. For Zone 1/Zone 2 installations, consult Bently Nevada for the appropriate intrinsically safe cable assembly.
Q: What is the maximum cable run length for the interconnect segment?
A: Bently Nevada specifies a maximum combined probe + extension + interconnect cable length. The CB2W100-015 at 1.5 m is within the standard system budget. Verify total cable length against your 3500 system TK-3 or equivalent specification sheet.
Q: Do you offer other lengths?
A: Yes. Contact support@konmask.com with your required length and we will source or quote the appropriate Bently Nevada part number.
Q: Is a Certificate of Conformance available?
A: Yes, upon request at time of order. Please note this requirement in your purchase order or order comments.
