1 Description of the product
Linear actuators RA 60 K consist of a direct current drive (volt-
age see technical characteristics), whose drive energy is trans-
ferred over a planetary gear and a spindle lifting gear to the
pushing rod.
The generated lifting force is available as push and pull force.
Linear actuators without stroke measuring systems are
equipped with internal limit switches. These avoid unintended
overrun and overload of the mechanical stop positions.
The end positions of linear actuators with stroke measuring
system are definable by the signal of the stroke measuring sys-
tem.
The sturdy design with code class IP69K guarantees a trouble-
free function also in rough operating conditions.
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 absolute stroke measuring system is equipped
with a linear potentiometer. A slider at the pushing rod pro-
duces a signal at the potentiometer, that is proportional to the
position of the pushing rod. This signal can easily be evaluated
by a priority control and is permanently available. Referencing
is not required. Due to the direct connection of the absolute
stroke measuring system to the pushing rod, one gets a precise
stroke information with slight backlash. This linear actuator is
equipped with a potentiometer and a subsequent amplifier that
generates a standardised output signal independent of the
stroke length. With the stroke measuring system, control-ori-
ented applications and the compound of several linear actua-
tors in synchronism can be realised.

Note
The version with (absolute) stroke measuring system is
equipped with a linear potentiometer.
This is evaluated according to the potentiometer principle (volt-
age divider).
For this purpose port d is connected to the reference potential
(0 V) and port e to the constant reference voltage.
At port c only a voltage can be tapped that is proportional to the
position of the pushing rod.
Thus, in retracted mode of the pushing rod a voltage can be
measured near the reference potential and in extended mode
near the reference voltage.
Generally the voltage at port c is connected to an analogous in-
put of the priority control, where it is evaluated.
The input resistance of the analogous input must be >1M ohm
to avoid any influences on the linearity of the absolute stroke
measuring system.
7.3 Mounting - installation
WARNING
Injury / burning due to contact with energized parts!
•Before working on electric equipment, the energized parts
must be de-energized and secured.
•Do not open protection covers at electric parts.
•All electrical works must only be realised by electricians.
Injury by crushing!
Components of the product make a movement while they are in
operation.
•This can cause injuries.
•Keep parts of the body and items out of the working area!
CAUTION
Injury by rotating parts!
The product does not have an anti-torsion device. The extend-
ing pushing rod and mounting parts can rotate.
•Operate the product only in installed condition.
Side loads and forced conditions on the product lead to
the premature failure.
•If required, provide external guides.
•Avoid forced conditions (overdetermination) of the product.
•Max. forces and torques see technical characteristics.
Fixing the connecting cable
• The cables must be fixed by the user so that no bending and
tensile stress will act and the cable cannot be damaged in
any way.
Component damage caused by faulty control
Use control of data sheet M 8.200.
If user's control is provided, this control must be equipped with
the following functions:
•switching off in case of over-current as protection against
blockade, collision, etc.
•current limitation as protection against damages,
•switching off in case of short circuits as protection against
overheating and fire, etc. and
•recognition of defect displacement transducer as protection
against damages, etc.
Do not approach the mechanical stops
It has to be guaranteed by the user's control that the element
will not be moved to the internal mechanical end positions.
1.Disconnect user's control from the voltage network.
2.Prepare the user's construction to mount the product. Pay
attention to sufficient freedom of motion.
3.Connect the product with the fork head at the front ant at
the rear by means of the user's fixing bolts to the user's
construction.
4.Secure the fixing bolts with convenient components of the
user.
