Bently Nevada 21747-085-01 Proximitor Probe Extension Cable

Overview

The Bently Nevada 21747-085-01 extension cable supports accurate vibration monitoring and reliable machinery protection in demanding industrial environments. The cable maintains stable signal transmission across long distances and integrates seamlessly with the 3300 XL Proximity Transducer System.

Structural Design

The 21747-085-01 uses an 85‑foot (25.9‑meter) cable that supports a 300V AC/DC voltage rating. The cable features a capacitance of ≤95 pF/m and maintains consistent performance in electrically noisy environments. The 95% copper braid shielding reduces interference and ensures clean signal delivery to the Proximitor Sensor.

The cable withstands temperatures from −40°C to +150°C and stores safely from −40°C to +150°C. The minimum bend radius of 75 mm supports flexible routing in compact machinery layouts. The design fits the standard 4‑hole mounting pattern used across 3300 XL installations.
