SKT
Protection class IP 65
q
The SKT is the smallest safety switch with a Available are:
Positioning the actuator head
l Rotation in 4 x 90° increments: when
mounted, the head is fixed into position
by the clasp
separate actuator offering the same fea-
l 1 NC p/1 NO slow-action device
tures, relating to safety, as all other produc- l 1 NC p/1 NO snap-action device
ts in this range. The SKT is perfect for
applications that require a particularly slim
and compact switching device. The rotating
head, two actuator openings and different
switching functions are proof of its versa-
tility.
The SKT offers further options enabling it
to suit a wide variety of applications.

Mechanical data
l Enclosure and lid made from highly
durable fiberglass reinforced thermoplas-
tic (UL 94-VO)
l Operating mechanism: head made from
PA, clasp from Zn, rivets from stainless
steel
– preventing unauthorized use of a spare l Actuator made from stainless steel
actuator to defeat the safety function
– ensuring the guard must be closed
securely to enable the machine to run
l Integrated actuator holding force
(FI50 = 50 N):
l Cable entry M 16 x 1.5
Guard doors which may open due to
vibration can be held shut by using the
SKT with increased actuator holding
force up to 50 N, without the need for
bulky external latches. In addition several
doors mounted in a straight line on one
machine are kept closed.
l Universal radius actuator (MRU):
In addition to the standard straight-on
actuator made from stainless steel (oper-
ating radius 150 mm), the universal
radius actuator offers an adjustable
operating radius to a minimum 50 mm
both horizontally and vertically.
The SKT offers a variety of different switch-
ing functions in a highly compact enclo-
sure. All systems are fitted with galvanically
isolated contacts, the normally-closed
being positive break. Snap-action contacts
have been designed for control systems
that require a simultaneous signal.

l The safety switch must not be used
as a mechanical end stop.
(0.91")
l To preserve the level of safety, the safety
switch must only be used in conjunction
with the correct actuator.
Mounting and installation
l The safety switch is mounted using 2 x
M5 screws in the provided locating and
mounting holes (23 mm centres).
l The separate actuator is attached using
2 x M4 screws (20 mm centres).
The safety switch and the actuator should
be secured well, in order to prevent unin-
tentional loosening (one-way and break-off
screws, rivets etc.)
