The 330980‑51‑CN is a proximitor (eddy‑current non‑contact displacement / vibration sensor) in the 3300 XL NSv family. The “51” indicates a 5.0 m system length and DIN‑compatible slim mounting form. The suffix “CN” denotes a regional / China compliance version (i.e. labeling, certifications, or packaging aligned with China / Asia market requirements). This sensor is engineered for use in tight mechanical spaces while meeting local regulatory demands.
The 330980‑51‑CN accepts 3300 NSv or RAM probes + extension cables and converts the probe’s gap variation (as shaft moves) into a voltage output. It offers improved electromagnetic compatibility (EMC) to maintain signal integrity under field conditions.

Notes & Context
Some listings show a weight of 0.22 kg for 330980‑51‑CN, likely referring to a different sub-variant (e.g. unpacked module) ([turn0search10]).
The published dimension 81.3 × 61.2 × 63.5 mm appears consistently in several vendor datasheets.
The “CN” suffix typically does not change the core electrical/mechanical performance — it indicates region-specific compliance.
The 330980‑51‑CN sensor is used in industrial monitoring tasks, particularly in constrained installation environments. Typical use cases:
Monitoring shaft vibration / displacement on turbines, compressors, motors
Axial (thrust) position measurement when flat faces or narrow envelopes are required
Keyphasor / phase reference signal in machine systems
Retrofitting older RAM / 190 / 3300 sensors into compact machinery layouts
Use in petrochemical, power generation, oil & gas, and advanced manufacturing plants
Environments requiring China‑approved sensors where local compliance matters
Its slim DIN form and regional compliance make it suitable where both geometry and regulations are constraints.
Slim / DIN-compatible design: Fits in tight cabinets or rack systems
Local compliance support (“CN”): Simplifies regional deployment
Strong EMI / RFI immunity: Maintains signal quality in noisy plant conditions
Stable output under supply variation: Less than 2 mV/V drift
Wide operating temperature envelope: –52 °C to +100 °C
Robust mechanical housing: Aluminum body able to survive industrial stresses
Tool-free wiring: SpringLoc terminals for field wiring ease
Probe & system compatibility: Works with 3300 NSv / RAM probes and extension cables
Versatility in measurement: Suitable for vibration, displacement, axial position tasks
