EMERGENCY STOP mushroom pushbuttons
These are used for safe and fast stopping of systems and machines in dangerous situations.
EMERGENCY STOP mushroom pushbuttons are certified according to DIN ISO 13850.
The illuminated versions of the EMERGENCY STOP mushroom pushbuttons improve the
visibility of the command point and can convey additional information.
EMERGENCY STOP devices can be connected directly via the standard ASi bus. This
applies to all SIRIUS ACT EMERGENCY STOP devices for front plate mounting and
mounting in enclosures.
A front plate-mounted EMERGENCY STOP can be connected directly to the ASi bus via a
fail-safe ASi module. For control systems according to IEC 60204-1 or DIN EN 60204-1
(VDE 0113 Part 1), the EMERGENCY STOP mushroom pushbuttons of the 3SU1 series can
be used as EMERGENCY STOP devices.
