Frequently Asked Questions (FAQ)

• Why is output voltage lower than 150V P-P?
  150V is at very high speed. Low speed output near 12.9V is normal.
• Can this sensor work with aluminum gears?
  No. Target must be ferrous metal like carbon steel.
• What happens if I reverse polarity?
  Signal flips but still works. Polarity matters for some controllers.
• How to extend cable length?
  Use shielded twisted pair cable. Max 300 feet.
• Experience tip: sensor fails after vibration?
  Check connector pins. Add thread locker for high vibration areas.
• Which sensor to pick for high temperature over 107°C?
  Choose AI-TEK high temp series. This model max 107°C.
• What gap gives best signal?
  Start at 0.010 inch. Reduce gap if signal is noisy.
• Buying guide: need high resolution at zero speed?
  This is passive. For zero speed, use active Hall sensor instead.

Selection Guide

• Use 70085-1010-002 for standard RPM tasks.
• Choose this model when no external power is available.
• Perfect for retrofit of older magnetic pickups.
• For extreme temperature, check AI-TEK HT series.
• Verify thread 5/8-18 matches your mounting hole.
