1) The external voltage supply of the devices must withstand a momentary power failure lasting 20 ms (to EN 60204).
Suitable power supply units are available from SICK as accessories (Siemens series 6 EP 1).
2) Under no load
3) Must not overrange or underrange UV tolerances
4) At T = + 25 °C and 100 mA output current
U
5) Signal transit time under resistive load
6) With light/dark ratio 1:1
