Key Performance Features
- Measures speed from near-zero to high RPM.
- No external power needed – self-generating magnetic design.
- High signal strength even at low speeds (1.6V guaranteed).
- Low DC resistance (125 ohms max) ensures clean output.
- Lightweight (2 oz) reduces stress on mounting.
Simple Installation & Care
- Clean the 3/8-24 threaded hole before mounting.
- Hand-tighten then turn 1/4 more with a wrench.
- Set air gap between tip and gear: 0.2 to 0.6 mm.
- Connect white lead to positive input, shield to ground.
- Check wires every year for cuts or loose connections.
- Wipe sensor tip with soft cloth if dirty.
Compatibility & Applications
- Works with PLCs, counters, tachometers, and frequency meters.
- Matches ferrous gears with 8 to 200 teeth.
- Use on conveyor motors, pumps, fans, and mixers.
- Great for overspeed detection and zero-speed shutdowns.
- Replaces many 3/8-24 magnetic pickups from other brands.
Smart Diagnostics & Troubleshooting
- Check output with an oscilloscope – clean sine wave = healthy sensor.
- No signal? Measure DC resistance across wires (should be ≤125 ohms).
- Low voltage? Reduce air gap or check gear surface condition.
- Signal drop at high speed? Look for loose mounting or vibration.
- Use a multimeter to confirm wire continuity.

- Also includes: quick guide and air gap card.
- Express shipping via FedEx, UPS, or DHL worldwide.
- Delivery time: 2 to 5 business days for most countries.
Frequently Asked Questions (FAQ)
- Q: Do I need to supply power to this sensor?
- A: No. AI-TEK 70085-1010-056 is passive magnetic. It creates its own voltage.
- Q: What is the smallest speed it can detect?
- A: At very low RPM (around 30 RPM) with a fine-pitch gear, you get the 1.6V guarantee point. Works near zero speed.
- Q: Based on your experience, what fails most often?
- A: Damaged wires from bending or pulling. Protect the 6-inch leads with flexible conduit.
- Q: Can I extend the wires longer than 6 inches?
- A: Yes. Use shielded twisted pair cable up to 50 feet. Keep away from power lines.
- Q: Which shipping method is fastest for my order?
- A: DHL Express is fastest for international. FedEx Priority also great. Choose at checkout.
Buyer’s Guidance
- Before buying: verify your existing thread is 3/8-24.
- Check gear tooth shape – this sensor works best on standard spur gears.
- Need a longer body? See other AI-TEK 70085 variants.
- Large volume orders: ask for bulk discount and free expedited shipping.
- 12-month warranty included. Keep invoice for any claim.
