- Resolution: Detects each ferrous target passage
- Air gap tolerance: 0.2 to 0.7 mm for reliable triggering
- EMI immunity: Excellent – no active electronics
Installation Guide (Simple Steps)
- Clean the 10-32 threaded hole before installation.
- Screw sensor gently until it touches the gear tooth.
- Back off 1/2 turn to set correct air gap.
- Tighten jam nut carefully – torque max 3 N·m (2 lb-ft).
- Connect white wire to signal positive input.
- Connect black or shield wire to signal ground.
Diagnostics & Maintenance Ease
- No calibration needed – install and run.
- Check output AC voltage while rotating shaft.
- Low voltage means air gap is too large.
- Inspect wire insulation for damage in hot areas.
- Keep sensor tip clean from metal debris.
Typical Applications (Where it shines)
- Very high temperature turbines (up to 232°C body).
- Tiny gear detection in tight machinery spaces.
- Cryogenic applications (-73°C).
- Speed feedback on small motors.
- Overspeed protection on compressors.
Compatibility Info
- Works with any PLC or tachometer accepting AC signals.
- Needs ferrous metal target (carbon steel gear).
- Not for use with stainless steel or aluminum gears.
- Compatible with most overspeed relays.

Frequently Asked Questions (FAQ) & Selection Guide
- Q1: How small is this AI-TEK sensor?
- Total length only 0.5 inch. Fits very tight spots.
- Q2: Why guaranteed output only 0.3V?
- That is the minimum at worst air gap/speed. Real output can reach 6V P-P.
- Q3: Can I use this sensor above 150°C?
- Sensor body survives 232°C, but wire insulation rated to 150°C only. Use high-temp extension for hotter areas.
- Q4: What happens if I reverse white/black wires?
- Output polarity flips, but most AC tachometers still work. Phase may reverse.
- Experience tip: Low output voltage?
- Reduce air gap to 0.3 mm. Also check gear material – must be carbon steel.
- Selection guide: Choose 70085-1010-182 when?
- Pick this model for extreme temperature (-73 to 232°C) and smallest 10-32 thread.
- Warranty support: 12 months from delivery.
- We cover manufacturing defects free within 12 months.
