Height
The height of the protected field describes the effective protected height, in which a matt,
opaque object corresponding to the specific resolution will be detected.

Overview
Operating Manual PSEN op4B/1 Series
1003356-EN-02 9
Width
The maximum width of the protected field is determined by the maximum operating range
of the light beam sent from the transmitter to the receiver.
In the table of product types, the maximum width for types with integrated muting sensors is
divided into a maximum width for the safety light grid and a maximum width for the muting
sensors.
}If the safety light grid is used without muting sensors, the width stated for the safety
light grid will apply.
}If the safety light grid is used with muting sensors, the width stated for the muting
sensors will apply.
The minimum width of the protected field corresponds to the minimum operating range
stated in the Technical details [ 62].
2.2 Unit features
Safety light grids in the PSEN op4B/1 Series are multibeam optoelectronic protective
devices for work areas in which
}machines,
}robots and
}automated plants
could endanger the physical integrity of operators.
Features of the safety light grid
}Type 4
}Safeguards protected fields with body resolution
}Muting
All safety light grids in the PSEN op4B/1 Series are able to process data from connec-
ted muting sensors
}Infrared protected field is generated
}Transmitter and receiver are synchronised optically
}Override
}LED for status information
}LED for support during alignment
2.3 Types
2.3.1 Safety light grid without integrated muting sensors
}Safety light grid with body resolution
The safety light grid is equipped for muting applications. External muting sensors with
reflective sensors or with transmitter and receiver sensors can be used for muting ap-
plications (see Order reference for accessories, section on muting
accessories [ 70]).
