Available now from Treotham Automation, the Wenglor P1MM001 is a reflex light barrier that can reliably detect objects at distances up to 500mm without using a reflector. The sensor needs nothing more than any suitably defined background as a reference, and this could be something like the side panel of a conveyor system.
According to Wenglor product manager Christoph Lang: “By doing away with reflectors, the reflex light barriers require less space and can be more flexibly integrated into the system layout. And thus they do justice to the trend towards more and more compact machines in the automation sector.”
The P1MM001 reflex light barrier also offers an intelligent function for dynamic readjustment of the switching threshold. This offsets external influences such as contamination and temperature fluctuations, ensuring precise switching performance and less idle time.
The use of visible red light makes the sensors easy to align, and they are easy to set up for any application by simply pressing the teach-in key.
The measuring process even detects transparent objects made of glass, PET and sheet materials. For example, in the beverage industry these sensors can be used to monitor the presence of bottles throughout the entire product lifecycle – beginning with bottle production and filling, right through to machines for the return of bottles with refundable deposits.
