di-soric safety light curtains/-light grids of series SL offer the optimal solution for all applications in the field of machine safety. Offering the safety classes of Type 2 and Type 4, all common safety applications can be covered. 

Numerous monitored heights and resolutions are available as a standard. Master-/Slave versions enable the individual arrangement of protective areas. The intelligent versions (SLI…) have an integrated control function (EDM). Versions in a water tight protection housing and heating function enable the use in the food and beverage industry.

di-soric safety relais of series SR are the ideal supplement for safety light curtain/-grids of series SLB. They offer an integrated control function (EDM). Remote muting sensors can be additionally connected to types of Series SR-M with integrated muting function.
The interface relais SR-0 perfectly matches the intelligent safety light curtains/-grids of Series SLI. Both positively driven contacts will be directly controlled and monitored by the safety light curtain/-grid.
