FAQ – Professional Answers

When do I need a 3 inch case length?
- When your machine wall is thicker than 2 inches.
- Standard 1.2 inch case is too short.
- Measure your mounting hole depth before ordering.
What does “no unthreaded tip” mean for me?
- Threads go all the way to the tip (00 option).
- You get maximum thread engagement strength.
- Good for high vibration machines.
Can I use this probe without a connector protector?
- Yes, this model has standard ClickLoc (02 option).
- No protector means smaller connector size.
- Fine for clean, dry environments.
What is the difference between 00 and 05 approval?
- 00 means no special approvals needed.
- 05 means multiple international approvals.
- Choose 00 for domestic non-hazardous sites to save cost.
What is the warranty and shipping?
- 12-month warranty covers defects.
- We ship within 12-24 hours after order.
- Carriers: FedEx, UPS, DHL with tracking.

Buying Guide – Real Experience Tips

Verify your mounting hole depth first.
- 3 inch case needs at least 3.2 inch deep hole.
- Measure before ordering to avoid returns.
Use a #3 tap drill for 1/4-28 threads.
- Larger drill sizes also work but may be loose.
- Do not exceed 0.375 inch thread engagement.
Check your proximitor cable length match.
- This probe has 1.0 meter cable.
- Proximitor calibration must match total cable length.
Torque to 5.1 N·m (45 in·lb) for best seal.
- Never exceed 7.3 N·m (65 in·lb).
- Use a torque wrench for accuracy.
Keep cable bend radius above 25mm (1 inch).
- Tighter bends break inner conductors.
- Use cable ties with soft edges.
