The AI-TEK 70085-1010-056 features a 3/8-24 thread for secure mounting and a 6-inch lead length for flexible wiring. Its high output voltage ensures clear signals even over long cable runs, reducing the risk of false readings.
Applications in Industrial Automation
This speed sensor is ideal for monitoring rotating equipment such as turbines, conveyors, and pumps. In a turbine overspeed protection system, the AI-TEK 70085-1010-056 provides precise speed measurement to trigger safety shutdowns. Its wide temperature range makes it suitable for outdoor installations and furnace-adjacent environments. The sensor’s 1.6V guarantee point ensures reliable operation even when the target is at a distance.
Installation Guidelines
Mount the AI-TEK 70085-1010-056 using the 3/8-24 thread into a tapped hole. Ensure the sensor face is positioned within the specified air gap for optimal signal strength. Connect the white lead to the positive input of your speed monitor and the remaining lead to ground. Verify output polarity before finalizing wiring. Use a shielded cable if the lead run exceeds 15 feet to minimize electrical interference. Tighten the sensor to a torque of 20-30 in-lbs to avoid thread damage.
Reliability and Maintenance
With no moving parts and a sealed design, the AI-TEK 70085-1010-056 offers long-term reliability. Its 22 mH inductance minimizes noise from nearby power lines. The sensor’s output voltage of 21V P-P provides a strong signal that resists attenuation, reducing the need for periodic recalibration. Inspect the cable insulation and connector integrity annually in harsh environments. If the output drops below 1.6V P-P, replace the sensor to maintain system accuracy.
