SICK WT24-2R210 Photoelectric Sensor – High-Precision Detection with Background Suppression

The SICK WT24-2R210 Photoelectric Sensor is designed for dependable object detection using advanced infrared LED sensing and background suppression technology. Built within a sturdy zinc die-cast housing and rated IP67, it performs reliably even in harsh factory environments. The unit can detect targets from 100 mm to 2,500 mm, maintaining consistent accuracy regardless of object color or surface reflectivity. Its broad 20 – 250 V AC/DC supply range and fast 10 ms response time make it ideal for packaging, logistics, and manufacturing systems where stability and speed are essential to prevent production downtime.

The WT24-2R210 offers both precision and versatility for industrial automation. It uses an easily adjustable potentiometer for fine-tuning the detection range and provides a change-over relay output for flexible light or dark switching. The metal enclosure withstands vibration and mechanical stress, ensuring long-term operational reliability from –40 °C to +60 °C. A clear LED indicator provides instant visual feedback of signal strength, simplifying setup and maintenance. This sensor excels in detecting diverse materials on conveyors or robotic systems, minimizing false triggers and ensuring continuous, fault-free production control.

The Applications of SICK WT24-2R210 Photoelectric Sensor

1. High-Speed Conveyor Bottle Detection

On automated bottling lines, precise detection of fast-moving containers is critical. The WT24-2R210 reliably identifies bottles of varying colors and materials using infrared background suppression, preventing false readings from conveyor reflections. Its rapid 10 ms response time allows it to keep pace with production speeds, while the 2.5 m detection range gives installation flexibility. Even in humid or glossy environments, it ensures stable performance, reducing line stoppages and improving quality control.

2. Pallet Height and Load Verification in Warehouses

In logistics centers, uneven or incomplete pallet loads can disrupt packaging or cause damage. The WT24-2R210 checks stacked boxes before wrapping by sensing the top layer precisely, regardless of color or material. Its robust zinc die-cast body withstands dust and vibration, while IP67 protection ensures reliable use around forklifts and conveyors. By eliminating missed or double detections, it enhances packaging accuracy and streamlines warehouse throughput.

3. Reflective Part Detection in Robotic Assembly

Robotic systems handling polished or metallic components often face errors due to glare or inconsistent surfaces. The WT24-2R210 resolves this challenge through infrared LED detection with background suppression, identifying shiny parts without interference. Operators can fine-tune sensitivity using the built-in potentiometer, ensuring consistent pickup points. Its fast response and rugged construction guarantee stable operation, minimizing downtime and maintaining precise robotic alignment during continuous shifts.

4. Transparent Film Positioning in Packaging Machines

In plastic film sealing or bag-forming machines, clear materials can confuse standard sensors. The WT24-2R210 detects transparent films by isolating the sensing zone and filtering out reflections from metal backgrounds. This maintains accurate feed control and prevents film misalignment or tearing. Mounted safely at a distance, it uses infrared light for consistent results even under high-temperature or reflective surfaces, improving process efficiency and reducing material waste.
