Light curtaine modules SAFEMASTER
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.

DOLD Safemaster - Modules for light barrier evaluation.

Light barrier evaluation devices are used to protect access to hazardous areas. Light barriers belong to the group of electro-sensitive protective devices (ESPE) which switch off the hazardous movement when persons and objects approach a danger point and thus initiate the safe state. If a machine operator must intervene regularly in a machine, it is advantageous to use ESPE instead of mechanical guards. This reduces the access time and at the same time increases productivity and ergonomics.

Your advantages at a glance:
- Up to cat. 4 / PL e or SIL 3
- Increased productivity due to shorter cycle times
