Expert Technical Evaluation & Performance Review
Signal Integrity and Output Characteristics

The 70085-1010-182 delivers a standard output voltage of 6 V (P-P) under normal conditions. Its guaranteed minimum output sits at 0.3 V (P-P) at the specified pick-up point. This ensures a usable signal even with slow-moving ferrous targets. The unit has a typical inductance of 2 mH and a maximum DC resistance of 50 ohms. These electrical characteristics define its compatibility with downstream controllers.
Harsh Environment Capabilities
This sensor excels in extreme thermal conditions. It operates reliably across a range from -73 to +150°C. The temperature rating for the component itself extends to 232°C. This makes the model ideal for monitoring turbines, engines, or gearboxes. You can deploy it in areas with high ambient heat without performance loss.
Mechanical Specifications for Installation

The unit features a compact 10-32 threaded body. Its thread length measures only 0.5 inches for easy mounting. The total sensor length is also 0.5 inches. This small footprint allows installation in tight spaces. The unit terminates with 18-inch wire leads for flexible routing. You must connect the white lead to the positive signal input.
Practical Application and Integration
You can use this sensor for precise rotational speed measurement. It requires a ferromagnetic target to generate its AC voltage. The wire termination simplifies connections to standard PLC or counter modules. Its light weight of just 1 ounce places no stress on mounting brackets. This model provides a direct and reliable method for speed sensing.
