Industrial Applications

1. Small Part Detection in Automated Assembly Lines

Utilizing its ultra-compact dimensions and diffuse reflective sensing, the EX-22B precisely detects small components on high-speed automated assembly lines without requiring a separate reflector. Its 0.5ms response time is crucial for rapid processing.

Problem Solved

Ensures accurate and quick presence/absence detection of miniature, often irregularly shaped, parts within extremely confined spaces on fast-moving conveyors or robotic cells.

2. Presence Sensing in Packaging Machinery

The compact design and 5-160mm sensing range of the EX-22B make it ideal for verifying component presence within packaging equipment, such as bottle capping or product insertion. The IP67 rating provides protection against typical packaging environment contaminants.

Problem Solved

Maintains product quality and prevents packaging errors by reliably detecting the presence (or absence via Dark-ON mode) of items like caps, labels, or products in dusty or occasionally moist packaging machinery.

3. Material Handling and Conveyor Control (Edge/Gap Detection)

With its side-sensing capability and robust operating temperature range, the EX-22B effectively detects object edges or gaps on conveyor belts for accurate positioning, counting, or spacing control in various material handling systems.

Problem Solved

Enables precise sorting, counting, and spacing of items on industrial conveyors by reliably sensing their edges or the gaps between them, functioning consistently across typical warehouse temperature fluctuations.
