Treotham Automation Pty Ltd introduces the SNH emergency stop buttons designed
for a wide range of industrial applications from elevators to packaging
systems.
An important component of safety technology solutions, the SNH emergency
stop button communicates with the safety switching devices of Series 4000 as
well as Samos and Samos PRO safety controls from Wieland Electric.
Treotham’s SNH emergency stop buttons are available as built-in or
surface-mount versions with a standardised installation diameter of 22mm. They
can be integrated in an operator panel or directly mounted to a machine using a
surface-mounted housing.
The contact blocks provide various wiring options as normally closed
and/or normally open contacts; additional normally open contacts can report
their status to a PLC. A separate contact element monitors the safe connection
between the emergency stop button and the switching contacts, avoiding accidental
failure and preventing the buttons from being bypassed.
The seven different sizes of the operating component can be combined
with numerous switching options resulting in a variety of switching variations.
Key features of SNH emergency stop buttons include detachable screw
connection terminals used for contacting the buttons; variations with
integrated LED lighting or buttons with blocking protection sleeves available
to avoid accidental operation; solutions with key and rotary switches available
for unlocking; and support for protection degrees up to IP69K.
