5 Professional FAQs
- Why does this model show guarantee voltage only?
AI-TEK gives low speed guarantee (13.4V P-P). High speed output can be much higher. - Can I cut and extend the 10m cable?
Yes. Use shielded twisted pair wire. Keep total length under 300 feet. - Experience tip: sensor reads intermittent signal.
Check 1/2 NPT conduit for water ingress. Dry and reseal the connection. - Choosing between 70085-3030-212 and shorter thread models?
Pick this 2.75 thread for thick housings. Short thread fits thin walls. - Does 12 month warranty cover cable damage?
No. Warranty covers sensor coil and internal parts. Cable damage is user responsibility.
Quick Selection Guide
- Need long reach? Choose 70085-3030-212 with 2.75 thread.
- Very cold environment? This works at -65°C.
- Want ready-made cable? This has 10m cable, no connector needed.
- For 1/2 NPT conduit systems – this is the right model.
