The information in the table relates to 90° beam deflection per mirror. If you need more advice on mirror
applications, please get in touch with your contact at SICK.
Do not use deflector mirrors if the formation of droplets or heavy contamination of the deflector mirrors is
to be expected!
7)
To meet the requirements of the relevant product standards (e.g. EN 61496
A
1), the external voltage supply
for the devices (SELV) must be able to bridge a brief mains failure of 20 ms. The power supply must provide
safe mains isolation (SELV/PELV) and have a current limit of max. 8 A. Power supplies according to
EN 60 204
A
1 satisfy this requirement. Suitable power supplies are available as accessories from SICK (see
section 10.6 “Accessories” on page 77).
