5 Professional FAQs

• Why guaranteed output is 4.2V but standard is 55V?
  4.2V is at very low speed. 55V happens at high speed. Both are normal.
• Can I use this sensor with a 3/8-24 hole?
  Yes. Thread size exactly matches. Do not force into different thread.
• Experience tip: signal drops when wires move.
  Check internal wire crimp. Add a small strain relief near sensor body.
• Which lead length to choose: -086 or -355?
  Pick -086 (18″) for tight panels. Pick -355 (40″) for longer reach.
• Buying guide: small gear or fine pitch?
  This 70085-1010-041 works best with small diameter gears. Lower voltage is fine.

Quick Selection Guide

• Need tiny sensor? Choose 70085-1010-041 with 3/8-24 thread.
