Product Description

The SICK UC12-12231 (6029832) is a high-performance ultrasonic distance sensor designed for precision measurement and detection in demanding industrial environments. Housed in a rugged, zinc die-cast cubic enclosure, it offers a compact footprint (15 mm x 48.8 mm x 43.5 mm) that is compatible with standard W12 series mounting accessories, facilitating easy mechanical integration. This sensor utilizes advanced ultrasonic technology to detect objects regardless of their color, transparency, or surface gloss, making it an ideal alternative to optical sensors in challenging conditions.

With an operating range of up to 250 mm and a limiting range of 350 mm, the UC12-12231 provides a high resolution of ≥ 0.1 mm and a repeatability of ± 0.15%. It features two complementary PNP digital outputs and integrated temperature compensation to ensure consistent accuracy despite ambient fluctuations. The sensor is built to withstand harsh environments, carrying an IP65/IP67 rating, and is highly resistant to dirt, dust, and moisture. Its intuitive Teach-in button allows for rapid configuration of switching points, enhancing process efficiency.

Key Performance Features

Extended Detection: Operating range of 55 mm to 250 mm with a limiting range of 350 mm.
High Precision: Resolution of ≥ 0.1 mm and repeatability of ± 0.15% for consistent results.
Fast Response: 30 ms response time with a 25 Hz switching frequency.
Environmental Stability: Integrated temperature compensation for high measurement accuracy during thermal changes.
Rugged Design: IP65/IP67 enclosure rating and a durable metal housing.
Versatile Outputs: Two PNP switching outputs (Q, /Q) for flexible control logic.
Material Independent: Reliable detection of shiny, transparent, or dark objects.

Ideal Applications

Level Control: Monitoring liquid or bulk material levels in small containers.
Diameter Check: Continuous monitoring of roll diameters for paper, metal, or plastic coils.
Transparent Object Detection: Reliable sensing of clear glass or plastic packaging that optical sensors may miss.
Positioning Tasks: Precise positioning of robot arms or conveyor components in assembly lines.
Harsh Environments: Applications in wood processing or metalworking where dust and cooling lubricants are present.
