Industrial Applications

1. High-Speed Small Part Detection on Automated Assembly Lines

The EX-19EB is ideally suited for precise detection of small components in high-speed automated assembly processes. Its ultra-slim profile enables integration into extremely confined spaces, while its rapid 0.5ms response time ensures no parts are missed, even on fast-moving lines.

Problem Solved

Ensures accurate presence/absence detection and counting of minute objects (down to ø2mm) in cramped, high-throughput manufacturing environments. The 4.5mm thickness and 0.5ms response time are critical for such applications.

2. Safety Interlock for Compact Machine Access Doors

With its side-sensing design and IP67 rating, the sensor reliably monitors the open or closed status of access doors and safety guards on industrial machinery, particularly where traditional sensors are too large. Its robust construction ensures reliable operation in harsh industrial settings.

Problem Solved

Provides dependable feedback for safety interlock systems on machine enclosures, preventing operation when doors are open. The IP67 protection handles dusty or wet conditions, and the compact side-sensing form factor allows for unobtrusive mounting in tight spaces.

3. Material Edge Alignment in Conveyor Systems

The EX-19EB's precise 0.05mm repeatability and narrow thrubeam sensing make it excellent for edge detection and alignment verification of materials on conveyor belts. Its 1-meter sensing range accommodates various conveyor widths and material sizes.

Problem Solved

Maintains precise alignment of products or materials on conveyor lines, preventing jams or quality issues due to mispositioning. The 0.05mm repeatability ensures consistent detection accuracy, while the 1m sensing range is versatile for different material handling setups.
