The fastening of safety switch and actuator has to be sufficiently stable to ensure the
proper operation of the safety switch and the actuator.
}
The distance between two safety switches must be maintained (see
).
}
Safety switches and actuators
–
Should be kept away from iron swarf
–
Should not be exposed to strong magnetic fields
–
Should be used for fixed wiring only
}
Prevent the safety switch and actuator being exposed to heavy shock or vibration
}
Make sure that the safety switch and actuator cannot be used as an end stop.
}
Circumvention of the safety switch in a reasonably foreseeable manner must be pre-
vented.
}
Please note the installation measures in accordance with EN ISO 14119 for a proximity
switch design 4 and with level of coding Low
}
Alignment errors of the guard must not adversely affect the safety function of the guard.
}
The assured operating distance S
ao
and the assured release distance S
ar
must be tested
under real conditions.

Install safety switch and actuator
–
facing each other in parallel,
–
) are exactly opposite
each other.
}
If possible, do not install the safety switch and actuator on to ferromagnetic material.
Changes to the operating distances are to be expected.
}
Safety switches and actuators should only be secured using M4 screws with a flat head
(e.g. M4 cheese-head or pan head screws). Use screws made of non-magnetic mater-
ial (e.g. brass).
}
A nib on the actuator prevents it twisting (see
On the mounting surface, drill a hole (
⌀
2 mm) as specified in the drawing, and place
the nib in the drill hole when installing the actuator.
