Ensure the sensor face is positioned at a distance that produces the guaranteed 4.3 V P-P output—typically within 0.050 in of the target. Connect the red lead to the positive input of your monitoring system and the black lead to common. Use the 10‑ft lead length to route wiring away from high‑noise sources. Verify DC resistance (130 ohms max) with a multimeter before energizing.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe AI-TEK 70085-1010-004 requires minimal maintenance. Periodically inspect the sensor tip for metallic debris or buildup that could alter the air gap. Check the cable jacket for cuts or abrasion in high‑vibration areas. Re-tighten the mounting nut to 10‑15 ft‑lbs after initial thermal cycling. The robust design supports continuous operation from -73°C to +107°C, reducing unplanned downtime.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eWhen selecting a replacement, verify thread size (5\/8-18), sensor length (2.125 in), and output voltage requirements. The 70085-1010-004 is a direct fit for many OEM applications.
