The 70085-1010-412 is an AI-Tek passive magnetic speed sensor. The official selection guide lists a 5/8-18 mounting thread, 13.4 V peak-to-peak guaranteed output under the stated test condition, wire termination, a 6 in threaded section, and a 7.25 in overall sensor length.

The sensor generates an alternating electrical signal as ferrous gear teeth or another suitable target pass the pole piece. Signal frequency follows target speed, while amplitude varies with surface speed, air gap, target size, and load impedance. It supports rotational-speed, frequency, and event sensing without an external sensor power supply.
Important Notice: Keep the supplied complete marking unchanged and verify nonstandard, placeholder, legacy, or MOD-controlled fields against the physical nameplate and current official documentation.

Gear-Tooth Speed Measurement
Detects passing ferrous teeth on rotating equipment
Tachometer Inputs
Feeds compatible frequency or speed channels
Engine and Turbine Speed
Provides passive rotational-speed sensing
Industrial Machinery Monitoring
Supports event and shaft-speed measurement
- Set air gap with the machine stopped and prevent contact with the rotating target
- Verify target material, tooth geometry, minimum speed, and load impedance
- Do not treat the 13.4 V value as constant outside the published test condition
- Confirm insertion depth so the long threaded body cannot contact moving parts
- Route and shield the two signal wires according to the receiving-instrument instructions
AI-Tek output is specified at a 0.030 in air gap and 500 IPS target surface speed. Actual output depends on surface speed, air gap, target geometry, and connected load impedance.
