Product Introduction
When speed sensor failure causes unplanned downtime in critical rotating machinery, the AI-TEK 70085-3030-112 provides dependable performance under extreme conditions. This industrial automation module is designed for precise rotational speed measurement in environments where temperature swings from -65°C to 95°C are common. With a robust 5/8-18 thread and 1/2 NPT conduit connection, it ensures secure installation in demanding applications.
Technical Specifications Breakdown

The high output amplitude ensures strong signal integrity even over long cable runs, while the wide temperature range prevents thermal drift and failure common in standard sensors. The 3-meter cable allows flexible placement without sacrificing signal quality.
Industry Applications
The AI-TEK 70085-3030-112 excels in three primary use cases:
-
Turbine speed monitoring: Withstands extreme heat from turbine housings and cold start-ups, preventing overspeed trips.
-
Conveyor systems: Reliable in dusty and vibrating environments, the sealed design and cable termination reduce false readings.
-
Pump feedback control: Accurate speed sensing for variable frequency drives, ensuring consistent flow and pressure.
In each scenario, the sensor's robust construction minimizes the risk of failure due to temperature cycling, a common cause of downtime in industrial automation.
Installation Guide
Proper installation of the AI-TEK 70085-3030-112 ensures reliable operation. Use the 5/8-18 thread for mounting directly into a sensor port or bracket. Secure the 1/2 NPT conduit fitting to prevent moisture ingress. Route the 3-meter cable away from high-voltage lines to avoid electromagnetic interference. Tighten the thread to manufacturer torque specifications—over-tightening may damage the sensor body.
Maintenance & Reliability
Routine inspection of the AI-TEK 70085-3030-112 focuses on cable integrity and thread tightness. Check for wear on the cable jacket every 6 months, especially near connection points. The sensor itself requires no recalibration under normal conditions. The -65 to 95°C temperature rating protects against thermal fatigue, extending service life and reducing replacement costs—key for cost-conscious operations.
Selection Guide & Purchasing Advice
Before ordering the AI-TEK 70085-3030-112, verify that your application matches the thread size (5/8-18), conduit thread (1/2 NPT), and cable length (3 m). If you need a different cable length or thread type, contact ubest101 for customized solutions. This sensor is ideal for replacing older units with similar mechanical footprint. Ensure the output voltage (13.4 Vpp) is compatible with your controller input specifications. PLC Source PRO offers genuine AI-TEK 70085-3030-112 modules with fast shipping.
