Product Description

The SICK UC12-11231 (6029831) is a high-performance ultrasonic distance sensor engineered for precision and reliability in demanding industrial environments. Housed in a compact, industry-proven rectangular zinc die-cast casing, this sensor utilizes advanced ultrasonic technology to detect objects regardless of their color, transparency, or surface finish. It operates within a precise range of 20 mm to 150 mm, providing consistent measurements even in the presence of dust, dirt, or steam.

The device features two complementary PNP digital outputs and is easily integrated into automation systems via a standard 4-pin M12 connector. With an ultrasonic frequency of 380 kHz and a fast response time of 30 ms, it ensures high-speed detection and positioning. The UC12-11231 is equipped with integrated temperature compensation to maintain accuracy across varying thermal conditions and offers intuitive “Teach-in” buttons for quick configuration of switching points. Its rugged construction and IP67 enclosure rating make it an ideal choice for applications requiring a durable, maintenance-free sensing solution that can withstand mechanical stress and contaminated surroundings.

Key Performance Features

Material Independence: Reliably detects transparent, dark, shiny, and high-contrast objects (e.g., glass, liquids, metal).
High Precision: Offers a resolution of ≥ 0.1 mm with a repeatability of ± 0.15% and an accuracy of ± 1%.
Integrated Temperature Compensation: Ensures stable measurement results despite fluctuations in ambient temperature.
Flexible Setup: Features a “Teach-in” button for simple configuration of Distance-to-Object (DtO), Window (Wnd), or Object-between-Sensor-and-Background (ObSB) modes.
Fast Cycle Times: Provides a switching frequency of 25 Hz and a low initialization time of less than 300 ms.
Robust Mechanics: Metal housing and a transducer made of polyurethane foam/glass epoxy resin provide high resistance to external impacts.

Ideal Applications

Level Control: Accurate monitoring of liquids and bulk materials in small containers or hoppers.
Diameter Checking: Precise detection of coil diameters for paper, plastic, or metal films.
Object Presence Detection: Identifying dark, transparent, or highly reflective objects on conveyor belts.
Positioning Tasks: Fine-tuned positioning of robotic arms or machine parts in automated assembly lines.
Packaging Industry: Monitoring the fill level or presence of clear glass/plastic bottles and films.
Quality Control: Checking for the presence of wire grids, fabrics, or irregularly shaped components.
