The Keyence AT-V500 amplifier unit is designed for advanced displacement and position measurement tasks, combining high-resolution sensing with robust functionality. This unit is compatible with dedicated sensor heads and delivers precise, real-time monitoring for a wide range of industrial automation and inspection needs. With its minimum display resolution of 0.1 µm and a sampling rate of 2000 measurements per second, the AT-V500 ensures reliable data capture even in high-speed processes, making it ideal for production environments where both accuracy and speed are critical.

The AT-V500 is equipped with a dual LED display system, featuring a two-color main 7-segment display (green/red) and a secondary single-color LED (red) sub-display. This configuration allows operators to view measurement values alongside secondary status information such as judgment results or statistical outputs. The display refreshes 20 times per second, and in cases of exceeding range limits, the system displays “±FFFFF,” ensuring quick recognition of out-of-spec conditions.

Connectivity and system integration are key strengths of this amplifier unit. It provides NPN open-collector outputs rated for 100 mA, supporting HIGH, GO, and LOW judgment outputs with configurable patterns. An analog ±5 V output with a 100 Ω impedance ensures smooth compatibility with monitoring equipment, while the RS-232C interface allows for measurement data transfer and remote control integration. With a response time as fast as 1.5 ms for digital output and 4.5 ms for analog output, the AT-V500 provides immediate and reliable feedback to external systems.

Functionally, the AT-V500 incorporates a wide range of advanced features to improve measurement flexibility and usability. Operators can make use of auto-zero adjustments, offset correction (4 sets), multiple judgment memories, and up to seven measurement modes tailored to different inspection needs. Additional functions include statistical display processing, averaging filters, internal trigger operation, calibration, analog scaling, and eco mode to optimize performance and energy efficiency. Together, these functions give users precise control over how measurements are displayed, processed, and transmitted.

Built for industrial reliability, the AT-V500 operates within an ambient temperature range of 0 to +50 °C and humidity of 35–85% RH, with resistance to vibration at 10–55 Hz, 1.5 mm double amplitude in all three axes. Compact and lightweight at approximately 200 g, it offers durability and ease of integration into panel systems while consuming only 150 mA at 24 VDC.

In summary, the Keyence AT-V500 delivers a high-performance blend of fast sampling, precise resolution, versatile outputs, and advanced functionality. It is ideally suited for demanding displacement measurement and inspection applications that require speed, precision, and seamless integration with modern automation systems.
