Industrial Applications

1. Transparent Bottle Presence Detection

In high-speed beverage bottling plants, this sensor can precisely detect the presence of clear PET or glass bottles on a conveyor before filling or capping stations. Its retro-reflective mode with transparent object detection and 0.5mm repeatability ensures accurate positioning and prevents misfills or machine jams.

Problem Solved

Reliably detects clear containers which are often challenging for standard photoelectric sensors, ensuring continuous and accurate product flow on automated lines.

2. Pharmaceutical Vial Inspection

Ideal for pharmaceutical production lines, where small glass vials or ampoules need to be verified for presence or correct alignment. The compact size and ability to detect objects down to Ø50mm transparent targets, combined with IP67 rating, make it suitable for sterile or washdown environments.

Problem Solved

Ensures accurate counting and positioning of small, transparent pharmaceutical containers in environments requiring high hygiene and precision, preventing production errors.

3. Automotive Component Assembly (Clear Parts)

In automotive assembly, particularly for interior components or fluid reservoirs made of clear plastics, this sensor can confirm the presence and correct seating of parts. Its robust IP67 rating protects against dust and splashes typical in manufacturing, and the wide operating temperature range (-25°C to +55°C) suits varying factory conditions.

Problem Solved

Accurately verifies transparent plastic components in harsh industrial settings, improving assembly quality and reducing manual inspection needs.
