Industrial Applications

1. Precision Part Detection in Automated Assembly Lines

This sensor is ideal for integration into automated assembly lines, particularly for electronics or small mechanical components. Its ultra-slim profile and narrow beam facilitate installation in extremely confined spaces, enabling precise detection of tiny parts.

Problem Solved

The compact design (3.5mm thick) allows the sensor to fit where conventional sensors cannot, ensuring reliable presence/absence detection of minute objects (ø0.5mm minimum detectable object) with high repeatability (0.05mm), preventing assembly errors and improving quality control.

2. Edge Detection for Web or Film Processing

The EX-11SA can be utilized in continuous web or film processing machinery to accurately detect and control the edge position of thin materials, crucial for precise cutting, winding, or printing operations.

Problem Solved

Its narrow beam and high repeatability (0.05mm) provide highly accurate edge detection for delicate and thin materials. The sensor's small size allows for close-proximity mounting of multiple units for fine control across a wider web, and the 0.5ms response time ensures real-time feedback for dynamic process adjustments.
