Key Features

Dual Analog Outputs: Simultaneously provides a 4-20 mA current loop and a 0-10 V voltage output proportional to the measured distance. This offers maximum flexibility for connecting to different industrial interfaces.

Teaching Function: Simple configuration via a built-in "Teach-in" button allows for quick and easy setup of the measuring range (e.g., setting near and far points) without the need for complex programming.

High Immunity to Interference: Ultrasonic technology makes it largely immune to target object color, transparency, or ambient light conditions. It is also resistant to dust, mist, and aerosols that often cause issues for optical sensors.

Adjustable Response Time: The response time can be configured to optimize performance between fast detection and stable filtering of signal noise.

LED Status Indicators: Integrated LEDs provide clear visual feedback on operating status, signal quality, and output state for easy commissioning and diagnostics.

Robust Housing: Built with a sturdy metal housing (M30 x 1.5 thread) offering a high degree of mechanical robustness and environmental protection rated at IP67, making it suitable for harsh conditions.

5. Typical Applications

The UM30-211118 is ideal for applications requiring accurate, non-contact distance measurement within its short range, especially where environmental factors challenge optical sensors.

Level Detection: Monitoring fill levels of liquids, granules, or powders in small containers, silos, or hoppers.

Position Control: Verifying the position of parts, tools, or doors in automated machinery and assembly lines.

Loop Control: Providing a feedback signal for controlling the diameter or tension of rolled materials (e.g., paper, film, wire).

Object Presence Checking: Detecting the presence or absence of objects on a conveyor, regardless of their color or surface finish.
