Benefits of this system
l All elements are enclosed in one metal
housing
l High resistance to heavy industrial use
l Compact housing for space saving instal-
lation
l Triple coded actuator with high
interference protection
l Simple alteration of actuator approach
direction in 90º positions (adjust only
with actuator fitted)
l All switch functions enclosed in inner
module
l Safe and easy wiring due to terminals in
separate connection area.
l Individual contact configurations possible
l Integrated safety circuit protects against
voltage peaks and incorrect termination
l Mounting with M 5 screws according to
DIN EN 50041

The safety-position switch (with suitable
control) will ensure that safety guards,
doors and other covers are kept closed as
long as there is danger.
locked or released (dependant on control
system/status of machine).
The separate actuator provides a very high
level of “operator interference” protection
because of its triple coding.
The safety switch has three main functions:
The locking device in the safety switch SLM
is integrated into the switch housing.
In the spring latch version locking is
l Allowing the machine to operate while
the guard is closed and locked
l Isolating the machine when the guard is achieved with a spring mechanism, in the
open
l Monitoring the position of the guard
and the actuator (open or closed)
solenoid latch version locking is achieved
by energizing an electromagnet. Both types
link the actuator with a switch mechanism
for position indication.
With the safety switch SLM the user has a
position switch with separate actuator and
built in locking device, which meets the cri-
teria of interlocking devices, according to
EN 1088, the EN 292 part I and 2 are also
valid since 01.01.1995 complying to the
necessary machine guide-lines.

The actuator head position may only
be changed with the actuator insert-
