## Balluff's Opto-electronic protective devices

Flexible production places high demands on safety when man and machine work so closely together.  
This interplay must not ever compromise the safety of employees. Opto-electronic protective devices such as light curtains from Balluff provide safe solutions that also enable great flexibility. Another benefit to you: by using light curtains that consist of multiple parallel light beams, you  
save space since they can replace cumbersome guard fence constructions or assemblies of multiple through-beam sensors.
