Key Features

IO-Link & Analog Output: Features a switchable output that can operate as a standard 4-20 mA analog current loop or as a digital IO-Link (COM2 / 38.4 kbaud) communication port. This provides backward compatibility with existing analog systems while enabling advanced digital capabilities.

Rich Data & Diagnostics: Through IO-Link, it provides access to extensive process data (e.g., measured distance, temperature, signal quality) and device status information (e.g., operating hours, error messages), enabling predictive maintenance and detailed process monitoring.

Simple & Remote Configuration: Offers multiple setup methods: traditional push-button "Teach-in" for quick setup or, more powerfully, remote parameterization and storage of multiple settings via IO-Link. This drastically reduces commissioning and changeover times.

Superior Environmental Immunity: Ultrasonic technology ensures reliable detection regardless of the target's color, transparency, or surface finish. It is highly resistant to interference from dust, mist, steam, and ambient light.

Integrated Temperature Compensation: Automatically compensates for changes in ambient temperature to maintain measurement accuracy and stability.

Robust Metal Housing: Housed in a durable metal body with an M30 x 1.5 thread and an IP67 protection rating, ensuring reliable operation in harsh industrial environments.

5. Typical Applications

The UM30-215118 is ideal for applications requiring both reliable control and detailed process data for optimization and maintenance.

Condition Monitoring: Monitoring vibration or positional drift of machinery by tracking minute distance changes over time, enabled by high-resolution IO-Link data.

Precision Level Measurement: Accurately measuring the fill level of liquids or bulk materials in small containers and transmitting the value via analog for control AND via IO-Link for visualization on an HMI or SCADA system.

Smart Warehousing & Logistics: Providing precise positioning data for automated guided vehicles (AGVs) and automated storage and retrieval systems (AS/RS).

Predictive Maintenance: Tracking its own performance (e.g., signal quality, internal temperature) via IO-Link to alert operators to potential issues before they cause downtime, such as transducer contamination.

Advanced Process Control: Using the rich data from IO-Link to make complex decisions in a PLC or controller, going beyond simple distance measurement.
