The Keyence AT-V501H Amplifier Unit is a high-performance measurement amplifier designed to deliver precise, rapid, and reliable signal processing in industrial automation environments. Built with sensor head interchangeability, it provides users with flexibility and compatibility across different setups, making it a versatile choice for diverse applications. This design enables users to seamlessly switch between sensor heads without the need for complex recalibrations, streamlining system integration and minimizing downtime.

A standout feature of the AT-V501H is its dual-display system, which includes a 7-segment, two-color LED (green and red) for primary measurement values and a secondary red LED sub-display. This arrangement enhances usability by clearly distinguishing operating statuses, measurement fluctuations, and judgment outcomes. Operators can easily identify acceptable ranges or deviations through visual cues, reducing the potential for errors during fast-paced operations. The display offers a resolution down to 0.1 µm, supporting applications that demand fine precision. With a display range extending from -99999 to 99999, the unit accommodates both small-scale micro-measurements and larger-scale variations, further broadening its utility.

Speed and responsiveness are at the core of this amplifier’s design. The AT-V501H processes measurements at a sampling rate of 2000 times per second, ensuring real-time feedback in high-speed production lines. Coupled with its 1.5 ms response time, it provides consistent accuracy even in dynamic applications such as part inspection, alignment monitoring, or process control. The inclusion of an over-range alarm, displayed as ±FFFFF, ensures operators are alerted immediately when measurements exceed the system’s limits, adding a layer of operational safety and reliability.

The control and output functionality of the AT-V501H further highlight its adaptability. It allows for four selectable patterns of upper and lower 2-level settings, enabling flexible HIGH/GO/LOW judgments. These outputs, delivered via NPN open collectors with a capacity of up to 100 mA at 40 V, ensure compatibility with a wide range of control systems. Input versatility is equally robust, with timing inputs, reset, auto-zero, and external setting signals. These features make it easy to tailor the amplifier’s operation to specific automation tasks, whether in assembly lines, inspection systems, or robotic integrations.

In terms of durability and consistency, the amplifier supports a display speed of 20 updates per second and provides selectable off-delay timing (60 ms) for stable signal processing. This ensures that even during high-speed production, operators and control systems receive accurate, filtered signals without noise-induced false triggers.

Overall, the Keyence AT-V501H strikes a balance between high-speed performance, precision measurement, and flexible control. It is particularly well-suited for environments where reliability and adaptability are critical, such as semiconductor production, precision machining, and automated quality assurance. Its intuitive display, fast processing, and comprehensive input/output options make it an indispensable tool for modern industrial measurement applications.
