Twisted signal pair
The two 22 AWG conductors in 84661-08 form the electrical path from the transducer connector to the terminal lugs.
Bently Nevada 84661-08 armored interconnect cable
Product Profile
Bently Nevada 84661-08 is an 8 ft armored interconnect cable in the 84661 family for carrying a vibration-transducer signal to a monitor or vibration data collector. Its twisted, shielded conductor pair carries the electrical signal, while the armored outer construction protects the cable along the installed route.
The two terminations give 84661-08 a defined signal direction: a moisture-resistant two-socket female connector mates with the transducer, and separate terminal lugs connect the conductor pair at the receiving instrument. The cable operating limit applies to this interconnect path and remains separate from the temperature ratings of the connected transducer and monitor.

Key Features — Armored Signal Cable
Mechanical protection and conductor organization work together in 84661-08 without changing the two-wire signal interface.
Shield plus armor
Shielding manages the signal environment while stainless armor on 84661-08 provides external mechanical protection.
Different end terminations
The female connector and terminal lugs on 84661-08 assign a clear transducer end and instrument end.
Installation Highlights — Eight-Foot Routing
Routing 84661-08 requires space for the protected cable body and service access at both unlike terminations.
Connector-side access
Leave space to engage and inspect the moisture-resistant connector of 84661-08 at the transducer.
Supported armor path
Clamp and support 84661-08 so its armor does not transfer cable weight into the transducer connector.
Lug identification
Preserve conductor and shield identification from 84661-08 when landing the lugs at the monitor or collector.
Product FAQs
Which end of 84661-08 connects to the vibration transducer?
The two-socket moisture-resistant female connector on 84661-08 is the transducer end. The individual terminal lugs belong at the monitor or vibration data collector.
Why should 84661-08 not be ordered as a generic eight-foot cable?
The 84661-08 identity includes twisted shielded 22 AWG conductors, stainless armor, a female connector, and terminal lugs. Length alone does not define those end treatments or the armored construction.
What should be checked when 84661-08 causes an intermittent reading after movement?
Inspect the connector engagement, armor transitions, supported bend points, and terminal-lug tightness on 84661-08. These checks locate a connection or routing problem before the transducer itself is disturbed.
Can 84661-08 be landed with the shield treated as a signal conductor?
No. The shield of 84661-08 must retain its documented shield function, while the two insulated conductors carry the transducer signal. Preserve the labeled wire relationship at the receiving instrument.
Is 84661-08 suitable for a route shorter than three feet by cutting it?
The documented 84661 family starts at 3 ft, and 84661-08 is manufactured as the 8 ft option. Field shortening changes the factory termination and should not be assumed equivalent to another catalog length.
What temperature boundary applies to 84661-08?
The standard 84661 armored cable family, including 84661-08, is specified for -50 to 120 °C. This cable limit is separate from the temperature rating of the connected transducer and monitor.
