❓ 5 Professional FAQs (New)
- Why are there two different lead lengths (-003 and -220)?
Pick -003 (12 inches) for tight junction boxes. Pick -220 (36 inches) when sensor sits far from your electronics. - Can I extend the wires myself?
Yes. Use shielded twisted-pair cable. Keep total length under 30 meters. - This sensor has 1/2 NPT conduit thread. Do I need conduit?
No, but conduit protects wires in wet or oily environments. Your choice. - Output is 150V standard but only 12.8V guaranteed – why?
150V happens at high speeds. 12.8V is the safe minimum at very low speeds (guarantee point). - What happens if I swap the white and other wire?
Output polarity reverses. No damage. Just swap back if your counter reads negative.
🛒 Buying Guide (real-world tips)
- Need shortest possible sensor? This 1.812 inch length fits tight spaces.
- Working in high vibration? Wires are better than connector – no loose plug.
- For very cold outdoor use (-55°C), this model works perfectly.
- If you need agency approval (UL/CSA), pick AI-TEK 70085-8080-050 instead.
- Pair with AI-TEK speed switch for complete over-speed protection.
