Deflecting mirror as accessory

Several sides of a danger point or a danger area can be protected using deflection
mirrors. The maximum width of the protective field is reduced by approximately 15 %
per mirror.

Protective screens against welding sparks

If SIMATIC FS400 3RG7845 is to be used in places exposed to welding sparks, we
recommend ordering transmitters and receivers with an additional protective screen to
protect against welding sparks. The additional protective screen (see accesories
Chapter 13.1.2) can also be easily exchanged after heavy stresses and demanding
work. Depending on the device length, the protective screen is fixed with two or three
brackets (see accesories Chapter 13.1.2) to the SIMATIC FS400 3RG7845 light
curtain or the SIMATIC FS400 3RG7845 light grid. With setting up protective screens
the range is reduced by approx. 10 % per screen (see, Chapter 13.1.2).
