Product Introduction
BENTLY 330101-00-12-10-02-05 is an 8 mm eddy current proximity probe. It mounts directly to the machine casing using a standard 3/8-24 UNF thread.
This specific 12-inch cable length reduces installation complexity compared to extension cable setups. The BENTLY 330101-00-12-10-02-05 offers a linear range of 2 mm with 7.87 mV/µm sensitivity. Verify target material conductivity against OEM specs before mounting.

Quality Control Process (Engineer’s Perspective)
- Incoming Verification: Trace source via serial number. Inspect probe tip for scratches or pitting.
- Live Functional Test: Connect to TK-3E calibrator. Verify linearity across full 2 mm gap.
- Electrical Parameter Test: Measure coil resistance and insulation (500 V Megger, >10 MΩ).
- Cable Integrity Test: Check continuity and shield grounding at connector.
- Final QC & Packaging: Seal in anti-static bag. Apply QC Passed label with date.
Replacement Pitfall Guide
❗ Cable Length Mismatch: The BENTLY 330101-00-12-10-02-05 has a fixed 12-inch cable. Adding extension cables changes system calibration.
❗ Thread Confusion: 3/8-24 UNF is not metric. Do not force M10x1 probes into UNF housings. Cross-threading destroys the casing.
❗ Target Material: Eddy current response varies with conductivity. Verify target material matches original OEM spec. Aluminum and steel behave differently.
❗ Gap Voltage: Set initial gap to -9 Vdc to -10 Vdc for steel targets. Well, technically you can use other points, but -9.5 Vdc is the industry standard center point.
❗ ESD & Handling: Never touch the probe tip with bare fingers. Skin oils attract debris and alter gap readings.
Keep these in mind and you’ll cut 90% of rework time.
