Industrial Applications

1. Conveyor Belt Object Detection in Packaging Lines

The CX-422 accurately detects the presence or absence of packages, products, or components on a conveyor belt, facilitating automated counting, sorting, and indexing processes. Its 800mm diffuse reflective sensing range is ideal for medium-distance detection, and the IP67 rating ensures reliable operation in dusty or occasionally wet packaging environments.

Problem Solved

Ensures precise product flow and prevents operational bottlenecks by consistently identifying objects on a conveyor, even in challenging industrial settings.

2. Part Presence Verification in Machining Centers

Integrated into CNC machines or robotic assembly cells, this sensor verifies the correct positioning and presence of workpieces, tools, or jigs before critical operations commence. Its compact size allows for installation in confined spaces, while the IP67 protection and wide operating temperature range (-25 to 55 °C) withstand harsh machining environments.

Problem Solved

Minimizes manufacturing defects and machine downtime by ensuring all components are correctly situated, thereby improving overall production quality and efficiency.

3. Non-Contact Level Sensing for Opaque Materials

Mounted above tanks or hoppers, the CX-422 can perform non-contact high or low level detection of opaque liquids, granular materials, or powders. The 800mm sensing distance provides flexibility in mounting positions, and the diffuse reflective sensing method eliminates the need for separate reflectors, simplifying installation.

Problem Solved

Prevents overfilling or running dry in storage containers by providing reliable level indications, which can trigger pumps, valves, or alarm systems in industrial processes. The IP67 rating ensures durability against splashes or dusty conditions.
