1 Description of the product
Linear actuators RA 600 consist of a direct current drive (volt-
age see technical characteristics), whose drive energy is trans-
ferred over a worm gear and a spindle lifting gear to the push-
ing rod.
The self-locking spindle lifting gear stops the actuator in case of
power failure and maintains it safely in the reached position.
Features of the sturdy design are the generous dimensioning of
the actuator and the solid design of the housing.
Linear actuators RA600 are protected against corrosion and
function without any troubles also in rough operating and envi-
ronmental conditions.
Since they are maintenance-free, this is permanently guaran-
teed.
Features of the sturdy design are the generous dimensioning of
the actuator and the solid design of the housing.
As an alternative to the code class IP66 also a press and
splash water protection as per code class IP69K is available.
Linear actuators are maintenance free and can be operated
with a duty cycle of up to 15%.
Version with limit switches
The version with limit switches has 2 integrated sensors, which
automatically switch off the motor as soon as the upper or
lower stroke end position is obtained. This guarantees that the
linear actuator does not mechanically push against the stop.
Version with stroke measuring system
The version with stroke measuring system allows the realisa-
tion of control-oriented applications and the operation of sev-
eral linear actuators in synchronism.
The stroke ends are freely definable by means of the digital sig-
nal.
Version with self-locking
All linear actuators are designed with a self-locking mechanism.
For higher safety in the case of a break an internal lock nut can
be provided.
This is possible as special solution on request.

- etc.
6 Application
6.1 Intended use
The electric linear actuator may be used for linear stroke move-
ment only.
It may only be centrically loaded with the maximum forces indi-
cated in the technical characteristics.
The electric linear actuator may be used in applications, where
a loss of the retention force can endanger the safety of the
user, with a safety nut only.
The decision whether the user is endangered must be taken by
the manufacturer of the application.
Every other use is not admissible.
Customer's modifications of the electric linear actuator are not
permitted.
The electric linear actuators must only be used within the envi-
ronmental conditions indicated below the technical characteris-
tics.
Note
Other demands on the use, service life and load have to be
agreed with the manufacturer.
The electric linear actuators have two fork eyes with Ø 12 mm
for the connection of the user's construction.
The connecting construction has to be designed so that no
forced conditions act on the pushing rod.
The electrical connection is made by coded plug-type connect-
ors.
Note
Design and dimensions of the connecting construction see
chapters Mounting and Installation!
The electric linear actuator must be installed protected against
torsion. The pushing rod must be installed without any side
loads.
NOTE
Durability and environment tests.
The product is designed for the use in outdoor applications and
is correspondingly resistant to corrosion.
•Before using this product the user has to check the usability
of the product for its application by own durability and envi-
ronment tests.
6.2 Misapplication

Note
The stroke end positions must not be loaded mechanically. An
approach in creep speed or switching off 3 mm before reaching
the end positions is required. For supply units with synchroniza-
tion control this is met by the programmed soft stop function.
The positioning accuracy with touch control amounts to
± 2 mm, depending on the operator and the load.
Place tasks with higher demands on the positioning accuracy
can be realised with special controls.
Therewith place accuracies can be realised within the size
range of the resolution of the stroke measuring system.
