Safety light curtain

A safety light curtain is an electro-sensitive protective device (ESPE) consisting of a sender and receiver. A series of parallel light beams forms a protective field between sender and receiver to protect the hazardous area. As soon as an object appears in the protective field, the safety light curtain signals the detection with a signal change at the safety outputs (e.g., OSSDs).
