The Keyence AS-440-05 Amplifier Unit, designed for use with the AH-416 sensor head, is a high-performance solution for precise displacement and position measurement. With a measuring range of 0 to 5 mm, this amplifier unit offers versatility for general-purpose applications where both accuracy and stability are critical.

One of its defining attributes is its resolution of 0.1% of full scale, allowing fine detection of even the smallest changes in position. This makes it suitable for demanding inspection and monitoring tasks where precise readings are essential. In addition, the AS-440-05 delivers reliable linearity at ±1% of full scale, ensuring measurement consistency across the entire range.

For applications involving fast-moving targets or dynamic processes, the AS-440-05 is engineered with a high response speed of 3.3 kHz (-3 dB). This rapid performance ensures that measurement signals keep pace with fluctuations, minimizing lag and enhancing process control. Combined with its stable 0 to 5 V analog output, the unit integrates seamlessly with control systems, data loggers, and industrial monitoring equipment. The low output impedance of 100 Ω ensures minimal signal degradation, making it suitable for long cable runs or connections to sensitive instrumentation.

Another key advantage is its robust temperature compensation. With a sensor head fluctuation of just 0.03% of full scale per °C, the system maintains measurement integrity in environments where temperature shifts might otherwise compromise accuracy. This reliability allows the AS-440-05 to perform consistently across varied industrial conditions, reducing the need for frequent recalibration.

Compact and versatile, the AS-440-05 is widely applicable in fields such as precision assembly, quality assurance, machine automation, and research environments. Its ability to provide stable, high-resolution displacement data makes it a valuable tool for engineers and technicians who require dependable results in both high-speed and high-accuracy scenarios.

In summary, the Keyence AS-440-05 Amplifier Unit combines accuracy, speed, and stability in a compact design. With its precise measurement capabilities, fast response, stable analog output, and excellent temperature compensation, it is a reliable choice for applications demanding consistent, high-quality displacement measurement.
