Frequently Asked Questions (FAQ)

• Why is the guaranteed output only 4.2V but standard is 55V?
  The 55V happens at high speed. The 4.2V is the minimum at low speed. Your instrument must work with 4.2V signals.
• Can I extend the 6-inch wires to go further?
  Yes you can. But keep total wire under 50 feet. Use twisted pair or shielded cable for long runs.
• Is this sensor replaceable with other 3/8-24 models?
  Yes, many AI-TEK sensors share this thread. Check the length and output specs before swapping.
• What happens if I connect wires backwards?
  The signal polarity reverses. Most PLC counters still work but phase may flip.
• How to choose between 70085-8080-001 and other AI-TEK models?
  Pick this for very small size (1.5 inch length) and 3/8-24 thread. Pick 70085-1010-004 for standard 5/8-18 thread and longer body.
