Bently Nevada 16925-25 Non-Armored Cable 16925 Series Complete Guide

Bently Nevada 16925-25 is a high-performance, non-armored interconnect cable engineered for precise vibration and seismic signal transmission in industrial machinery monitoring systems. As part of the trusted 16925 Series, this 25-foot (7.6-meter) cable provides a reliable connection between Bently Nevada accelerometers and seismic transmitters to monitoring systems, ensuring critical vibration data is delivered with minimal interference from industrial electrical noise.

Manufactured in the USA, the 16925-25 features a flexible 3-conductor shielded design that balances signal protection with installation flexibility, making it ideal for routing through conduits, cable trays, or within equipment cabinets.

Key Features

Extended 25-Foot Length: Provides ample reach for sensors located at moderate distances from junction boxes or monitoring racks 

Low-Noise Shielded Conductors: 22 AWG design with shielding protects against electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring reliable low-voltage signal transmission 

Flexible Non-Armored Jacket: Easy to route in tight spaces and conduit runs without the stiffness of armored alternatives 

Standard Industrial Termination: MIL-C-5015 3-socket plug at the sensor end and terminal lugs at the system end for secure, moisture-resistant connections 

Wide Temperature Range: Operates reliably from -40°C to +85°C (-40°F to +185°F), suitable for harsh industrial environments 

Flame-Retardant Jacket: PVC jacket material provides additional safety in industrial settings
