Monitor light barriers and light grids
If persons or objects approach a dangerous area, the DOLD light barrier switching devices deactivate the dangerous movement via contactless safety devices (AOPD) and ensure a safe condition. The light barrier switching devices are used to protect persons that regularly during the handling process must reach into machines and systems that are also a source of danger. A typical application is the conveying and removal of work pieces to presses. A benefit of this solution is higher productivity through longer cycle times as well as by refraining from mechanical safety devices – without having to reduce the safety level.
