Industrial Applications

1. Precision Part Detection in Automated Assembly Lines

In high-speed automated manufacturing, the EX-24A can precisely detect small components like chip parts or minute mechanical fasteners on conveyor belts, ensuring accurate placement and preventing production errors.

Problem Solved

Its ultra-compact size (4.5mm thick), convergent sensing (2-25mm range), and ability to detect objects as small as Ø 0.1mm copper wire with 0.1mm repeatability and sub-millisecond response time (<0.5ms) make it ideal for detecting tiny objects in space-constrained environments without impeding line speed.

2. Wafer Protrusion Check in Semiconductor Manufacturing

The sensor is perfectly suited for detecting minute protrusions or irregularities on semiconductor wafers, which is critical for preventing damage during processing and maintaining product integrity in advanced electronics fabrication.

Problem Solved

The EX-24A's precise convergent sensing (0.1mm minimum detectable object), compact form factor, and stable detection against reflective surfaces (common for wafers) provide reliable non-contact inspection. Its IP67 rating ensures durability and compatibility with cleanroom conditions where environmental control is paramount.

3. Object Sensing in Small Openings or Gaps of Industrial Machinery

This sensor can effectively monitor the presence or passage of objects through narrow openings or within confined spaces in industrial machinery, enhancing operational safety and process control.

Problem Solved

The extremely small body dimensions (18x16x4.5mm) and front-sensing capability allow the EX-24A to be mounted in minimal gaps or tight spaces where larger sensors cannot operate. Its standard 12-24VDC supply voltage and NPN output are fully compatible with typical industrial control systems.
