Product Description

The Keyence UD-300 is an ultrasonic displacement sensor amplifier unit designed to provide precise, non-contact measurement of various materials, including metals, glass, rubber, and even powders and liquids. When paired with compatible sensor heads like the UD-310, UD-320, or UD-360, it delivers high-resolution measurements suitable for applications such as level sensing, thickness gauging, and dimensional inspection in automated systems. The UD-300 offers features like 4–20 mA analog output, relay control outputs, and alarm functions, all housed in a compact, IP65-rated enclosure suitable for industrial environments.​
