The Keyence AS-440-10 (AS-440-10U) amplifier unit is a versatile, general-purpose device engineered to deliver reliable displacement and position measurements in industrial environments. Designed for use with the AH-422 sensor head, this amplifier unit ensures stable performance across a wide range of applications that require precise, non-contact detection and monitoring. With a cylindrical, threaded 22 mm housing, the AS-440-10 is compact, robust, and easy to integrate into both new and existing equipment, offering durability and flexibility for long-term use.

One of its standout qualities is the ability to provide high-accuracy measurements with a resolution of 0.1% of full scale. This makes it particularly effective in tasks requiring repeatable precision, such as part alignment, dimensional verification, or quality inspection processes. The measuring range of 0 to 10 mm covers small to moderate displacement needs, giving it versatility for a variety of applications in industries such as electronics, automotive, and machinery manufacturing.

The amplifier delivers an analog output voltage of 0 to 10 V with a low 100 Ω impedance, which enhances compatibility with numerous control and monitoring systems. This wide output range allows engineers to achieve smooth signal integration with programmable logic controllers (PLCs), data acquisition systems, and other industrial automation equipment. The result is a seamless connection that supports real-time monitoring and control, ensuring efficient workflow in production environments.

Equally important is the AS-440-10’s rapid response capability. With a response frequency of 3.3 kHz (-3 dB), the amplifier unit is able to track fast-changing targets and deliver accurate output signals with minimal delay. This makes it highly suitable for high-speed manufacturing processes, such as dynamic inspections, assembly line monitoring, and high-precision positioning systems where rapid response is critical.

The unit’s linearity of ±1% of full scale further supports reliable performance, ensuring consistent correlation between actual displacement and the output signal. This minimizes measurement errors and contributes to higher product quality and reduced waste in production. Additionally, the robust mechanical design allows for easy installation in demanding industrial environments, where vibration, temperature changes, and long operational hours are common.

Overall, the Keyence AS-440-10 (AS-440-10U) amplifier unit combines high precision, fast response, broad output capability, and a durable build, making it an ideal choice for industries that require dependable displacement measurement. Whether used for quality inspection, alignment verification, or process monitoring, it offers the performance and reliability needed to maintain accuracy and efficiency in modern manufacturing.
