In the most diverse industries, automation specialists wishing to detect shiny and uneven objects – foil-wrapped six-packs or shiny metal surfaces – by using photoelectric sensors, were faced with three problems until now: incalculable reflections from the film, uneven surfaces, eg, in case of containers in the area of shrink-wrapped bottlenecks, and different container heights depending on bottle size.
Dual receiver system with application software
The WTB27-3 Multipac ignores the previous limits for detecting highly reflective and at the same time uneven surfaces. This is achieved by the ideally adjusted combination of three primary measures: the use of two completely separate receiver systems doubles detection performance; a high-power LED generates an extremely high light intensity and application-specific software controls the complex evaluation.
This compact photoelectric proximity sensor is the future-proof solution for checking and controlling, for example, the transport of packaging units on single or multi-track conveyor systems. In addition, sensor may be mounted up to 500 mm above the conveyor system in order to detect diverse types and heights of packaging units from one fixed sensor position. As a result, the mechanical height adjustment often required until now becomes unnecessary, which significantly reduces effort and expense for users.
Users confirm that the solution offered by the WTB27-3 Multipac ensures a level of reliability unprecedented in practical operations to date.
