7.3.1 Type 4, multi beam
To meet the requirements of EN 999 you can install single beams in the shown heights
above floor. You can make it more simple by using multibeam sensors like Omron’s
F3SH 4-beam safety sensor where the beam gap is already according to EN 999.
7.3.2 type 2, single beam
For type 2 applications it is common to use single photoelectric sensors.
This sensor can be combined with as much beams as required from the risk
assessment. For palletisers and depalletisers (EN 415-4) where only sporadic access
is necessary this is a often used application.
To maintain safety the sensors must be tested by a dedicated and approved controller.
The requirements for design to prevent bypassing and defeat must be in accordance to
EN999.
To obtain a good assembly the M18 sensors with ranges up to 10 m are a appropriate
solution. Depending on the solution it is necessary to chose between metal or plastic
body as well as between prewired and connector types.
