Frequently Asked Questions (FAQ)

1. Is the 330101-00-43-10-02-CN probe pre-calibrated?

   Yes, it’s factory-matched and calibrated as a system with its extension cable and Proximitor® sensor.

2. Can this model be used in applications with chemical exposure?

   Yes, the stainless steel housing and sealed connector system make it resistant to most industrial chemicals.

3. What is the recommended torque for installation?

   For the 1/4-28 thread, use around 1.5–2.0 N·m (13–18 in-lb) to avoid over-tightening.

4. What is the “CN” suffix in the part number?

   It typically indicates compliance with Chinese regulatory and certification standards.

5. Does the cable length impact accuracy?

   Yes, the probe and extension cable must be used together as specified. Mixing lengths can distort calibration.

6. Is this probe hot-swappable?

   No. Always shut down monitoring systems before disconnecting the probe to prevent signal error or system faults.

7. How can I verify proper probe gap during installation?

   Use a micrometer tool or feeler gauge and check for the standard -8 VDC output at the desired gap (usually 2 mm).

8. Can I cut or modify the probe cable?

   No, cables are pre-terminated and matched. Modifying length or connectors voids calibration and may damage the system.

9. What should I do if the probe output voltage is unstable?

   Check cable integrity, grounding, and ensure the probe is securely mounted and aimed at a clean, ferrous target surface.

10. Is this product compatible with wireless vibration transmitters?

    Not directly. It’s designed for wired Proximitor® systems, but data can be fed into wireless transmitters via compatible interfaces.
