Where It Excels in Industrial Use

• Armored Velocity Sensor Interconnect Cable
The Bently Nevada 84661-46 Velomitor Interconnect Cable is designed to connect Bently Nevada Velomitor velocity sensors to compatible vibration monitoring systems. It provides a rugged, shielded signal path for industrial machinery condition monitoring applications. The 84661 family is specified as a two-conductor twisted, shielded 22 AWG armored cable with a moisture-resistant sensor connector and terminal/ring lug termination.

• Rotating Machinery Vibration Monitoring
The cable is used with Velomitor velocity sensor installations on critical rotating equipment such as turbines, compressors, pumps, motors, and generators where accurate vibration velocity signals are required for machinery protection and predictive maintenance.

• Harsh Industrial Environments
The stainless steel armored construction provides additional protection against abrasion and mechanical damage, while the shielded cable design helps minimize electrical interference and maintain vibration signal integrity.

• Extended Sensor-to-Monitor Routing
The “-46” suffix indicates a 46 ft (approximately 14.0 m) cable length option, providing extended installation flexibility between field-mounted Velomitor sensors and monitoring cabinets. The 84661 series uses the suffix number to identify cable length in feet.
