Product Introduction
BENTLY 330101‑00‑12‑10‑02‑05 is an 8 mm eddy‑current proximity probe from the 3300‑XL platform. It detects conductive target surface distance without physical contact. This specific part ships without metal armor over its integral cable, suited for protected cabinet or conduit‑routed installations.
Probe case length is 120 mm with zero unthreaded section, and comes with 1.0 m built‑in cable terminated by miniature ClickLoc coaxial connector. The 05 suffix adds international hazardous‑area approvals. The probe alone cannot deliver usable readings; the full system requires a matching 3300‑XL proximitor sensor plus extension cable to hit the required total system length. Measurement linear window runs from 0.25 mm to 2.3 mm target gap —though your mileage may vary if target material is not standard carbon‑steel or if total system cable length deviates from configured value.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Source traceability, serial number cross‑check. Visual inspection for tip damage, thread burrs, cable cuts, connector pin deformation. Confirm full part number 330101‑00‑12‑10‑02‑05.
- Live Functional Test: Bench test with calibrated target gap fixture; verify gap‑voltage slope matches nominal sensitivity. Insulation resistance check between center conductor and shield. Document serial against factory calibration data.
- Electrical Parameter Test: Insulation resistance (500 V Megger, >10 MΩ). Reject units showing low isolation.
- Documentation Review: Confirm hazardous‑area certification paperwork matches suffix‑05. Well, technically the probe itself has no configuration parameters; total system cable length must be programmed inside the paired proximitor sensor. Mismatched length causes offset and sensitivity error without hardware fault indication.
- Final QC & Packaging: Anti‑static bag; include lock‑nut, mounting torque instruction sheet, protective connector dust cap.
Replacement Pitfall Guide
❗ Full‑System Length Rule: This probe’s 1.0 m integral cable adds to extension‑cable length. Total system length (probe + extension) must exactly match the setting programmed in the 3300‑XL proximitor sensor. Wrong length produces wrong gap readings, no fault alarm.❗ Target Material Effect: Stainless‑steel or alloy shaft targets shift effective sensitivity. Apply published material correction factor; do not rely on nominal carbon‑steel calibration values.❗ Mounting Torque Limit: Do not exceed 8.1 N·m torque. Over‑torque crushes internal probe coil and permanently degrades performance.❗ Non‑armored Cable: This variant has no stainless‑steel armor. Protect cable from sharp edges, abrasion and high mechanical crush loads; use conduit in exposed field runs.❗ Connector Handling: ClickLoc coaxial contacts are delicate. Keep dust cap fitted when disconnected. Moisture or dirt inside the connector creates intermittent drift faults that are hard to isolate during commissioning.❗ ESD Damage: Use anti‑static wrist strap while handling open connector. Static discharge can shift coil characteristics with zero visible damage.
Keep these in mind and you’ll cut 90% of rework time.
