The 89477-17 is a premium, industrial-grade Interconnect Cable Assembly engineered specifically for critical machinery condition monitoring systems. With a pre-cut length of 17 feet, this two-conductor 18 AWG twisted shielded cable serves as the vital physical telemetry link between field-installed Bently Nevada Velomitor Piezo-velocity Sensors and centralized monitoring platforms like the Bently Nevada 3500/42M or 3500/44M vibration monitor modules.
2-Conductor, 18 AWG, Twisted Shielded Pair
MIL-C-5015 standard 2-socket right-angle stainless steel plug
This cable is precision-matched to complement the solid-state architecture of Bently Nevada piezoelectric accelerometers. Because Velomitor sensors contain embedded integrated electronics with no moving parts to measure absolute bearing housing, casing, or structural vibration at any mounting angle, they demand a high-integrity signal path that eliminates data loss.
The 89477-17 guarantees near-zero signal attenuation, ensuring that the high-frequency vibration data captured by the solid-state sensors is transmitted with absolute accuracy to prevent catastrophic machinery failure. Wrapped in a weather-resistant Fluorinated Ethylene Propylene (FEP / Teflon) outer jacket, the cable exhibits exceptional resistance to aggressive industrial chemicals, hazardous solvents, synthetic lubricating oils, and moisture ingress.
Features a comprehensive braided shield architecture that suppresses severe electromagnetic and radio-frequency interference commonly found near high-voltage motors, steam turbine generators, and large variable frequency drives (VFDs).

Oil & Gas Refining
Connects the Velomitor sensor installed on the bearing housing of the Fluid Catalytic Cracking (FCC) main blower in crude distillation units. It safely transmits casing vibration signals to the 3500 monitoring rack under high-temperature and oil-mist environments.
Thermal Power Generation
Used for casing vibration monitoring of large boiler induced draft (ID) fans and forced draft (FD) fans. The right-angle 2-pin connector fits inside the tight space of the fan casing's protective cover, preventing high-temperature dust ingress.
Nuclear Power Plant
Connects the absolute casing vibration sensor on the steam generator main feedwater pumps in the conventional island of a nuclear power plant, providing an anti-EMI signal path for the highly reliable nuclear auxiliary drive train.
Hydroelectric Power Generation
Used to monitor the structural vibration of the upper guide bearing and thrust bearing housing of large vertical hydro-generator units, resisting moisture dissipation and strong magnetic field interference around heavy generators.
Marine & Offshore Engineering
Used for casing vibration monitoring of the main propeller shafting and large marine turbochargers on ocean-going cargo ships. The stainless steel connector provides excellent protection against salt spray corrosion.
First, maintain shield integrity. Never splice or cut the cable in the field, and ensure the drain wire (shield) is properly single-ended grounded at the monitor side to prevent ground loop noise.
Second, rout properly away from high power. Maintain safe separation from high-voltage power cables or run through independent metal conduits to avoid electromagnetic coupling interference.
Third, mind plug protection and bend radius. Although the right-angle plug saves space, ensure it is fully and tightly seated, and avoid over-bending the cable near the connector boot.
Fourth, use with housings in harsh environments. In areas with extreme moisture, water spray, or high mechanical wear, it must be installed inside the 21128 velocity transducer housing.

Technical notes
Technical notes
89477-17 is designed specifically for Velomitor velocity sensors, featuring a weather-resistant Teflon (FEP) jacket that provides outstanding high-temperature, anti-corrosion, and anti-electromagnetic interference performance.
It is a two-conductor 18 AWG twisted, shielded cable assembly, featuring a right-angle two-socket plug at one end and terminal lugs at the other end.
How to properly use a product like 89477-17?
Plug the right-angle two-socket end into the compatible vibration sensor interface, and connect the terminal lugs at the other end to the input module of the monitoring instrument.
Which specific equipment is 89477-17 primarily used with?
It is primarily used with Bently Nevada monitors, velocity sensors, and the 21128 Velocity Transducer Housing.
Why does 89477-17 use a twisted and shielded design?
The twisted and shielded design is engineered to minimize electromagnetic interference (EMI) in harsh industrial environments, ensuring accurate transmission of weak vibration signals.
What is the advantage of the right-angle plug of 89477-17 in field installation?
The right-angle (90-degree) plug reduces the vertical space required for cable exit, making it ideal for compact wiring within tight machine enclosures or protective housings.
