Product Description Locking Modules
Guard locking devices of the SAFEMASTER STS/K (FRP) family combine the proven operating principle and the advantages of electromechanical
safety switches with 2-channel guard locking function. Thanks to guard lock monitoring, they can be used for both process and reliable personal
protection. Different coding levels, very high locking forces and extensive diagnostic options enable use in almost any safety-relevant application.

Cat. 4 / PL e
SIL 3
Mechanically Coded Actuators
Actuator J With Self-Adjustment
Actuator CS
Double Actuators
SAFEMASTER STS/K systems can
be used as individual solutions in
applications up to category 4,
Performance Level e according to
EN ISO 13849-1 can be used.
All actuators belonging to the
SAFEMASTER STS/K system are
also available in the coding level
medium, according to
EN ISO 14119:2013.
When plugged in, the J actuator
is self-adjusting over 4 degrees
of freedom and retains its last
alignment state.
It can have an offset of up to
20 mm to compensate.
The CS actuator is particularly
suitable for harsh and dirty ambient
conditions. In addition, the CS
actuator is designed for applications
with high shear and tensile forces,
so that overload breaks can be
largely excluded.
For applications with Performance
Level e, SAFEMASTER STS/K
units can also be equipped with 2
actuators.

SAFEMASTER STS/K Basic unit ZRH01BM/K / 11.01.21 en / 355A
SAFEMASTER STS/K systems are
logic units for safety functions
according to Annex IV, S21 and are
EC type tested in accordance with
legal requirements.
The C actuator with adjustable
actuator angle is spring-mounted.
It returns to its set state after a load.
The CW bolt moves under the
mounted unit, making the slider
suitable for securing hinged doors
with both left and right stop.
It is designed in such a way that
shear forces cannot act directly
on the STS/K unit. It is particularly
suitable for applications, where high
forces can act on the STS/K units,
e.g. in double swing doors.
The holding force F
according to
zh
EN ISO 14119:2013 is 2000 N.
(stainless steel versions 4000 N)
SAFEMASTER STS/K units with
double actuators can be used to
monitor 2 adjacent accesses.
