5 Pro FAQs
- How low can speed go before output drops too much?
At very low speed (below 30 RPM), output may fall under 0.6V. Use a gear with more teeth to raise signal. - My sensor works then stops. What happened?
Check the air gap first. Heat can expand parts and push sensor away. Reset gap to 0.005-0.015 inch. - Can I use this with a long cable (over 50 feet)?
Yes but signal gets weaker. Use a signal conditioner like AI-TEK 70085-8080-001 to boost it. - Buying guide: 70085-1010-299 vs 70085-8080-004?
This one (299) is for tight, very hot or cold spots. The 8080-004 is bigger and for normal temps. - Warranty & shipping: what do I get?
12-month warranty against defects. We ship via FedEx, UPS, or DHL with tracking.
Where to Use It
- Cold storage conveyor belts
- Oven exhaust fan speed check
- Small motor RPM feedback
- Compressor shaft position
- Laboratory test rigs
Installation Tips
- Point sensor tip straight at gear teeth
- Keep gap between 0.005 and 0.015 inch
- Tighten gently – 10-32 thread is small
- Use a lock washer to stop vibration loosening
