    Description
    Linear actuators RA 600

    RA linear actuators are used for electrically-operated adjustments and as actuating elements in applications with control-oriented demands in short-time service.

    Description
    Linear actuators RA 600 consist of a 24 VDC direct current drive, whose drive energy is transferred over a snail transmission and a spindle stroke transmission to the pushing 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.
    As an alternative to the code class IP 66 also a press and splash water protection as per code class IP 69K is available.
    Linear actuators RA600 are protected against corrosion and function without any troubles also in rough operating and environmental conditions. Since they are maintenance-free, this is permanently guaranteed.

    The version with limit switches is equipped with 2 sensors, that prevent an unintentional movement to the mechanical stroke ends and thus the overload of the mechanics.
    The version with stroke measuring system allows the realisation of control-oriented applications and the operation of several linear actuators in synchronism. The stroke ends are freely definable by means of the digital signal.

    Operation
    Linear actuators RA 600 can optionally be operated by hand panel or foot switch and supply units of the accessory programme as per data sheet M8.200 with touch control or by an external control with 24 V output.
    The version with stroke measuring system delivers the user incremental signals of the stroke measuring system.

    Version with limit switches
    The version with limit switches has 2 integrated Hall-effect sensors, which automatically switch off the motor brake 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. At the plug-type connector of this version the pins 3 and 4 have to be connected to 24 VDC. By changing the polarity, switching over from retracting to extending is effected.

    Version with stroke measuring system
    The stroke of linear actuators is transmitted by potential-free square wave signals, which are generated by the rotating spindle, to an external control. An additional reference point, that initialises the stroke measuring system, is in the retracted stroke end position. This reference point can also be used to switch off the retracted stroke end position.
    With the incremental stroke measuring system control-oriented applications and the compound of several linear actuators in synchronism can be realised. Due to the incremental acquisition of the position, faults of linearity are excluded.
    Supply units as per page M8.200 treat the actuators and the user's connecting construction with care due to a special control and thus contribute to the increase of the service life.
