Note:
The through-beam safety light barrier is an electro-sensitive protective device in connection with a safety-relevant control system where the cyclical testing of transmitter and receiver is carried out according to EN-/IEC 61496-1, -2, category 2 (testing). The supply unit operating the light barrier must intercept changes and interruption of the supply voltage according to EN-/IEC 61496-1. Minimum diameter of darkening object Ø 13 mm.
