Safety Position Switch on machine with a protective device and
swivel joints – a typical application, e.g. in automated parts
processing
Safety Switches are used for the position monitoring of moving
protective devices, such as protective doors or flaps. Safety
Switches without guard interlocking can always be used when
the dangerous movement has stopped before the entering
person can reach the point of operation. The Leuze electronic
Safety Switches portfolio also includes Safety Position Switches
(S300) and Safety Hinge Switches (S400) and therefore provides the perfect solution for many different applications.

SAFETY LOCKING DEVICES OVERVIEW
The Leuze electronic Safety Locking
Devices completely cover the entire
spectrum from normal to very high
requirements (from left to right):
L10, L100, L200
Safety Locking Devices selection table Selection table
Safety Locking Device as access guarding
Safety Locking Device on a metal processing center with
stopping times
Safety Locking Devices keep the protective door locked and
therefore prevent inadmissible access by people. The access to
the danger zone is only released by an electric signal when
either the dangerous movement has stopped (personnel protection) or an uninterruptible work process has been finished
(machine protection). All Leuze electronic Safety Switches and
Locking Devices are configured with their robust design for use
in tough industrial applications and prove their value under the
most demanding operational conditions.
