sicherheitslichtgitter and appropriate procedures for monitoring a schutzbereichs

摘要

The safety light grating has two transmission and receiving blocks (2,2') with a light emitter (S1.1,S1.2,S1.3,S1.4,S2.1,S2.2,S2.3,S2.4) and a light receiver (E1.1,E1.2,E1.3,E1.4,E2.1,E2.2,E2.3,E2.4). The transmission and receiving blocks are arranged opposite to each other, and a protection field (1) is formed between the transmission and receiving blocks. One of the light emitters of one of the transmission and receiving blocks forms a light sensor with one of the light receivers of the same transmission and receiving block. An independent claim is included for a method for monitoring a protected area.
