Industrial Applications

1. Small Component Detection on Conveyors

Used in a high-speed electronics assembly line to confirm the presence of small surface-mount devices (SMDs) on a printed circuit board (PCB) before it enters the reflow oven. The sensor is mounted directly above the conveyor belt.

Problem Solved

The sensor's narrow, convergent beam and fast 0.5ms response time allow it to reliably detect very small components at high conveyor speeds, preventing costly errors where components are missing before the soldering process. The IP67 rating protects it from dust and occasional cleaning sprays in the factory environment.

2. Pharmaceutical Vial Counting and Positioning

Installed on a pharmaceutical bottling line to count clear or semi-opaque vials as they pass a specific point. The sensor ensures each vial is correctly positioned before being filled or capped.

Problem Solved

Standard diffuse sensors can struggle with reflective or transparent materials. The EX-44's convergent sensing method provides stable detection of the vials, independent of their color or transparency. Its high repeatability (0.2mm) ensures precise position verification for automated filling heads, reducing spillage and waste.

3. Lead Frame Detection in Semiconductor Manufacturing

Integrated into a die-bonding machine to detect the leading edge of a metallic lead frame. The sensor's output triggers the machine's pick-and-place mechanism to accurately position the semiconductor die.

Problem Solved

The application requires precise, non-contact detection within a confined space. The sensor's compact dimensions (10x18x37mm) allow for easy integration. Its focused convergent point ensures that only the lead frame is detected, ignoring the background just millimeters away, which is critical for preventing machine crashes and ensuring accurate die placement.
