Frequently Asked Questions (FAQ)
- What is the minimum target speed?
About 5 RPM with a 60-tooth gear. Output drops below 200 Hz. - Can I use this sensor in water?
No. IP67 is for temporary immersion only. - Why is my output voltage low?
Check the air gap. Reduce to 0.010 inches max. - Does it work with stainless steel gears?
Yes, but output drops 20%. Use ferrous gears for best result. - How to choose between this and 70085-1010-210?
The 220 version has longer thread (2.937 vs 1.5 inches). Pick 220 for thick mounting brackets. - My sensor gets hot at 100°C. Is that normal?
Yes. Up to 107°C is safe. Above that, replace it. - Can I cut and extend the wires?
Yes. Use shielded cable and keep total length under 30 meters.
Selection Guide
- Need shorter thread? Choose 70085-1010-210 (1.5 inch).
- Need higher temperature? Choose 70085-1010-250 (150°C max).
- Need explosion proof? This model has no ATEX rating. Look for 70085-EX series.
- For very low speed (<5 RPM), add a signal amplifier like AI-TEK 10000-1.
