Industrial Applications

1. Conveyor Belt Package Detection

Utilizes the BGS (Background Suppression) feature of the CX-445B to detect packages on a conveyor belt without being falsely triggered by the moving belt or varying background reflections.

Problem Solved

False triggering from background movement or highly reflective conveyor surfaces.

2. Automated Assembly Line Part Presence

Mounted in tight spaces of assembly machinery using its compact W11.2mm x H31mm x D20mm dimensions to verify the presence of metallic or non-metallic parts during indexing.

Problem Solved

Component space constraints in automated assembly stations preventing installation of standard-sized sensors.

3. Electronic Component Positioning on PCB Assembly

Employs the precise red LED spot (approx. 8mm diameter at 50mm) to align and detect circuit board edges or component carrier positions on high-speed SMT placement machines.

Problem Solved

Slow response times in high-speed sorting and positioning stages.
