FAQ

Q1. What does the “330902” prefix mean?
A1. It identifies the probe model: 3300 NSv series, ¼‑28 UNF thread, with armor. According to the datasheet figure: “330902 = ¼‑28 UNF‑2A, with armor.”

Q2. Is this part just a cable or a full probe + cable assembly?
A2. The listing indicates a “Sensor Proximity Probe Cable”, but the Bently ordering scheme typically combines probe + integral cable

 in one part number (especially for NSv series). Given the “05” total length (0.5 m) code and the “02” cable type, it

is likely a probe with integral cable assembly rather than just a field wiring cable.

Confirm with manufacturer.

Q3. Can I use this with a Proximitor sensor from another series (e.g., 8 mm or 11 mm series)?
A3. For best performance, Bently says that the probe, extension cable (or integral cable), and Proximitor sensor should 

all belong to the same series (NSv in this case). Using mismatched series may degrade

 linearity, scale factor, or interchangeability.
