The Keyence AS-440-02U amplifier unit is designed for high-precision analog measurement applications, delivering exceptional accuracy and stability in a compact, user-friendly package. Paired with the AH-110 sensor head, this system is ideal for applications requiring sub-millimeter resolution, such as quality control, positioning verification, and precision manufacturing processes.

One of the defining features of the AS-440-02U is its high-precision analog output. The unit provides a 0–2 V output with 0.1% full-scale resolution and linearity of ±1% F.S., allowing for accurate real-time monitoring of distance or displacement. This performance ensures that engineers and technicians can rely on consistent, reproducible measurements for critical production processes. The output impedance of 100 Ω further supports stable integration with PLCs, data acquisition systems, or other industrial controllers.

The compact M10 threaded AH-110 sensor head provides flexible mounting options in applications where space is limited. Its precise measuring capability‚Äîcovering a range of 0 to 2 mm (0.08″)‚Äîmakes it especially suitable for detecting small displacements or fine surface variations. This is particularly valuable in industries such as electronics, automotive, and mechanical engineering, where micro-scale accuracy is often required.

Temperature stability is another critical advantage of the AS-440-02U. With a minimal temperature fluctuation of 0.03% F.S./°C at the sensor head, the unit maintains reliable performance even in environments where thermal variations are present. This ensures high repeatability and reduces the need for frequent recalibration, saving time and maintaining operational efficiency.

Additionally, the AS-440-02U amplifier unit features a fast response rate of 3.3 kHz (-3 dB), enabling high-speed measurement in dynamic environments. This makes it ideal for applications involving rapid movement or vibration, where precise, real-time feedback is essential.

Overall, the Keyence AS-440-02U combines precision, compact design, and robust performance to deliver reliable analog measurement for demanding industrial applications. Its combination of accuracy, stability, and high-speed response ensures it is a dependable choice for engineers and technicians aiming to optimize production quality and measurement efficiency.
