Description
These rope-operated safety switches are installed on machines or conveyor belts and allow the machine to be brought to an emergency stop from any point and with any pull on the rope. This means significant cost savings for medium and large machines, since
multiple emergency-stop buttons can be replaced with a single switch. They are equipped with a self-control function that constantly checks the correct function and signals a possible loosening or breaking of the rope through the opening of the contacts. These
safety switches keep the contacts open after activation until the reset is performed, even if the rope is released.
Head with variable orientation
For all switches, the head can be adjusted in 90° steps after removing
the four fastening screws.
Extended temperature range
These devices are also available in a special
version suitable for an ambient operating
temperature range from -40ºC up to +80°C.
They can therefore be used for applications in cold stores, sterilisers
and other equipment with low temperature environments. The special materials used to produce these versions retain their characteristics even under these conditions, thereby expanding the installation
possibilities.
Indicator for rope adjustment
Tension indicator
Area of correct rope
tightening
contacts.
If the tension (or loosening) on the rope is so high that the black
indicator exits the green area, the electrical safety contacts will open
and the reset device will trigger.
All switches are provided
with a green ring that shows
the area of the correct
tightening of the rope. The
installer has only to tighten
the rope until the black indicator will be in the middle of
the green area. With this setting, the switch can be reset
by pulling the blue knob to
close the electrical safety
Laser engraving
All devices are marked using a dedicated
indelible laser system. These engravings are
therefore suitable for extreme environments
too. Thanks to this system that does not use
labels, the loss of plate data is prevented and
a greater resistance of the marking is achieved over time.
Protection degree IP67
These devices are designed to be used in the toughest environmental conditions and they pass the
IP67 immersion test acc. to EN 60529. They can
therefore be used in all environments where maximum protection
degree of the housing is required.
Reduced actuating force
These switches can be supplied with reduced hardness
internal springs on request. The
force required to actuate the
switch can thereby be reduced
without changing the actuating
path of the electrical contacts.
This is particularly advantageous for smaller spans, but
must, however, always make
use of rope pulleys.
Indicator for the state of the reset
Armed reset
If the tension indicator is in the green area, the electrical safety contacts can be closed by pulling the blue knob. The reset status can be
identified quickly by the green ring under the blue knob.
