Industrial Applications

1. Transparent Bottle Detection in Beverage Bottling Lines

The sensor's ClearSens technology and autocollimation principle allow it to accurately detect transparent PET or glass containers with zero blind spots. Its 1000 Hz switching frequency easily accommodates the rapid throughput of modern conveyors, ensuring each bottle is accurately counted before filling and capping stages.

Problem Solved

Reliably detecting clear PET or glass bottles on high-speed conveyors without false triggers caused by glare or unpredictable optical reflections.

2. Shrink-Wrapped Pallet and Film Detection

Utilizing its specialized optical evaluation logic and IO-Link configuration, the sensor can be finely tuned to recognize the presence of thin, glossy wrapping films. The PinPoint LED ensures a highly concentrated light spot, penetrating glare and ensuring automated packaging machinery operates without material feed errors.

Problem Solved

Standard photoelectric sensors struggle to detect thin, highly reflective plastic shrink films used in automated packaging processes.

3. Precision Part Positioning in Space-Constrained Assembly Cells

The ultra-compact VISTAL housing (12.1 x 41.9 x 18.6 mm) is engineered to fit directly into tight machine profiles. With an impressive 7.1m detection range, M8 connectivity, and rugged IP67 rating, it provides consistent part-in-place verification without interfering with the robot's strict motion path.

Problem Solved

Limited physical space in modular robotic cells requires sensing components that are extremely miniature yet highly capable over varied detection distances.
