Industrial Applications

1. Automated Conveyor System Object Detection

This sensor can reliably detect the presence or absence of packages or components on a conveyor belt in manufacturing or logistics facilities. Its 5-meter sensing range is suitable for wider conveyors or for detection across a path, while the compact size allows for easy integration. The IP67 rating ensures durability in environments with dust or occasional splashes.

Problem Solved

Prevents product bottlenecks or miscounts by accurately confirming object passage and position, even in industrial environments.

2. Industrial Automatic Door/Gate Control

The CX-493 can be used for activation and safety in industrial automatic door or gate systems, such as those found in warehouses or factory entrances. Its 5-meter range allows for early detection of approaching vehicles or personnel, and the robust IP67 construction handles outdoor or semi-outdoor industrial conditions, including temperature fluctuations from -25°C to +55°C.

Problem Solved

Provides reliable and safe operation of automatic doors/gates by detecting obstructions and triggering opening/closing sequences.

3. Stacker Crane Positioning in Automated Storage and Retrieval Systems (AS/RS)

In AS/RS, the CX-493 can assist in precise positioning and collision avoidance for stacker cranes or shuttles. Its 5-meter retro-reflective sensing provides accurate distance measurement to ensure correct shelf alignment or detect obstacles within the aisle. The 0.5mm repeatability is crucial for high-precision operations in automated warehouses.

Problem Solved

Enhances the accuracy and safety of automated storage and retrieval systems by providing reliable position feedback and obstacle detection for moving equipment.
