Its white lead is positive, ensuring correct polarity during installation. The wide temperature range and robust DC resistance of 125 ohms max minimize signal degradation in high-heat zones.\u003c\/p\u003e\u003ch2\u003eIndustry Applications\u003c\/h2\u003e\u003cp\u003eIn high-temperature environments such as gas turbines, kilns, and engine test stands, standard sensors fail due to thermal stress. The \u003cstrong\u003eAI-TEK 70085-1010-472\u003c\/strong\u003e withstands continuous exposure up to 232°C, delivering consistent 4.7 V P-P output. Its 60-inch cable length allows placement away from extreme heat sources while maintaining signal integrity. Common failure modes like signal dropout or false triggering are reduced by the sensor's stable inductance (5-12 mH) and low DC resistance.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Setup Guidance\u003c\/h2\u003e\u003cp\u003eMount the \u003cstrong\u003eAI-TEK 70085-1010-472\u003c\/strong\u003e using the 1\/4-40 threaded body. Ensure the thread length of 0.687 inches engages fully for a secure fit. Connect the white lead to the positive input and the other wire to ground. The sensor delivers an AC voltage proportional to speed; verify output with an oscilloscope. Avoid over-tightening to prevent thread damage. For applications near moving ferrous gears, maintain an air gap of 0.020 to 0.040 inches for optimal signal.\u003c\/p\u003e\u003ch2\u003eMaintenance \u0026amp; Reliability\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eAI-TEK 70085-1010-472\u003c\/strong\u003e requires minimal maintenance due to its solid-state design. Inspect the cable periodically for cuts or abrasion, especially in high-vibration areas. The 2 oz lightweight construction reduces mechanical stress on mounting points. Temperature cycling between -73°C and 232°C may cause slight changes in inductance, but the sensor's reference inductance range (5-12 mH) accommodates typical variations. No agency approvals are required, simplifying replacement in non-certified environments.\u003c\/p\u003e\u003ch2\u003eSelection Guide \u0026amp; Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore purchasing the \u003cstrong\u003eAI-TEK 70085-1010-472\u003c\/strong\u003e, verify the required thread size and cable length. This model has a fixed 60-inch cable. For custom lengths, contact your supplier. Ensure your target gear material is ferrous for proper magnetic pickup.
