Industrial Applications

1. Transparent Bottle Detection on a Conveyor Line

In a beverage bottling plant, this sensor can be installed alongside a conveyor belt to accurately detect the presence of clear PET or glass bottles. Its retroreflective sensing mode is specifically designed for transparent objects, ensuring that each bottle is counted or triggers the next step in the packaging process.

Problem Solved

Standard photoelectric sensors often fail to detect transparent objects. The CX-481's specialized optics and sensitivity adjustment solve this by reliably sensing the slight change in light as a clear bottle passes, preventing miscounts and production errors. The IP67 rating ensures it can withstand washdown environments common in food and beverage facilities.

2. Clear Film Presence Verification in Packaging Machinery

Used within a packaging machine to confirm that a continuous sheet of clear plastic film is correctly positioned before a sealing or cutting operation. The sensor's fast 1ms response time is critical for keeping up with high-speed automated packaging lines.

Problem Solved

Ensures that packaging material is present before the machine attempts to wrap a product, preventing wasted product and machine jams caused by missing film. The sensor's compact size (11.2x31x20mm) allows for easy integration into the tight spaces of complex packaging equipment.

3. Glass Pane Handling in Automated Assembly

This sensor can be used in an automated system that handles glass sheets, such as in the manufacturing of windows or solar panels. It verifies that a robotic gripper has successfully picked up a sheet of glass before transporting it.

Problem Solved

Prevents the automation system from proceeding with its cycle if a glass pane was not picked up, which could lead to machine damage or process failure. The 50 to 500mm sensing range provides flexibility in mounting distance, and the robust PBT housing protects the sensor from potential impacts in a dynamic manufacturing environment.
