Installation

3.1 Installation

Mounting instructions

– Install the devices solidly on a stable, vibration-free
holder.
– Be sure that the orientation of the devices cannot
change during startup or in normal operation.
Especially the emitter and receiver must not be
permitted to move relative to each other, since
otherwise incorrect measurements and failed object
detection can result.
– Locate the devices where they are protected against
the accumulation of dust, dirt or liquids.
– Do not install the devices in a location where they are
exposed to direct sunlight or strong ambient light,
since excessive ambient light can result in faulty
measurements.
The device can be installed horizontally or vertically.
Fastening options:
Custom fastening system
Two M4 screws are used for fastening. Use either two of
the three through holes on the top side or the two threa-
ded holes on the side.
Mounting brackets from Balluff
The supplied stainless steel mounting brackets allow
flexible positioning and easy alignment of emitter and
receiver by slotted holes.
