The Keyence AS-440-01U amplifier unit is a general-use device engineered to deliver high-performance signal amplification and accurate measurement for industrial and precision applications. Specifically designed for pairing with the AH-305 cylindrical sensor head, it provides seamless compatibility in setups requiring fine measurement control. With a compact cylindrical design and a diameter of just 5.4 mm, the unit is well-suited for integration into tight spaces where conventional amplifiers may not fit, making it highly practical for environments with spatial constraints.

A standout feature of the AS-440-01U is its precise analog output voltage capability. The unit delivers a consistent 0 to 1 V signal with a low impedance of 100 Ω, ensuring stable transmission of measurement data without significant signal degradation. This makes it highly suitable for integration with controllers, monitoring systems, and data acquisition devices. The analog output is supported by a resolution of 0.1% of full scale, providing detailed feedback for applications that demand high measurement accuracy. Such precision is valuable in industries like electronics, automotive manufacturing, and research laboratories where even slight deviations can impact quality or performance.

Linearity is another defining aspect of this amplifier unit, with a tolerance of ±1% of full scale. This ensures that the output signal remains consistent and proportional to the input measurement, maintaining reliability across its entire 0 to 1 mm measuring range. This level of accuracy makes the AS-440-01U an excellent choice for precision positioning, dimensional measurement, and other metrology tasks. The design focus on stability helps reduce potential measurement errors, supporting quality assurance processes and productivity.

The AS-440-01U also excels in speed. With a response frequency of 3.3 kHz (-3 dB), it is capable of capturing rapid changes in measured values, enabling real-time monitoring in fast-moving processes. This rapid responsiveness is essential in automation, robotics, and assembly line operations, where quick and accurate feedback loops are critical to efficiency and process control. By providing fast output, the amplifier reduces delays in system responses, contributing to higher throughput and reduced error rates.

Durability and versatility also characterize the AS-440-01U. Its robust cylindrical design enhances installation flexibility while ensuring consistent performance even in challenging industrial conditions. The unit’s straightforward output structure simplifies integration into a wide variety of setups, from single-point measurement applications to more complex multi-sensor configurations.

In summary, the Keyence AS-440-01U amplifier unit offers a balanced combination of precision, speed, and reliability. With its high-resolution measurement, linearity, fast response, and compatibility with the AH-305 sensor head, it is a dependable solution for a wide range of industrial and scientific measurement applications. Whether used in automated manufacturing systems, laboratory testing environments, or precision inspection stations, this amplifier unit provides consistent performance that enhances accuracy, productivity, and reliability.
