Objective:
Reliably detect translucent glass vials without false triggering.

Solution:
In packaging applications, photoelectric sensors are the standard sensor technology for part presence detection on conveying systems. Translucent or shiny materials such as vials, ampoules and other glass packages, cause frequent problems with common sensing technologies. Problems include double-counts, caused by multiple reflections of one bottle, as well as false-negative detection from a small change in reflectivity of the passing object. Both scenarios are very likely and relatively unpredictable.

Capacitive sensor offer a new approach to achieving long-term, reliable and versatile object detection of glass packaged products. These sensors detect the core material characteristics, disregarding optical features and influences. Balluff’s stainless steel portfolio of capacitive sensors offers a wide range of high performance sensors for object detection, making your next presence detection application safe and reliable.
