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-
1
duces a signal at the potentiometer, that is proportional to the
position of the pushing rod. This signal can easily be evaluated
1
by a priority control and is permanently available. Referencing
2
is not required. Due to the direct connection of the absolute
stroke measuring system to the pushing rod, one gets a precise
2
stroke information with slight backlash. This linear actuator is
equipped with a potentiometer and a subsequent amplifier that
2
generates a standardised output signal independent of the
2
stroke length. With the stroke measuring system, control-ori-
ented applications and the compound of several linear actua-
3
tors in synchronism can be realised.
