    Description


    The KD-ACT series of actuators are programmable devices that can be used in a variety  of applications.  When used with our electronic controller, this actuator can be commanded to any desired rotational position: 0 to 180 degrees. 
    Onboard drive electronics perform automatic position verification and error correction.

    Each actuator is fitted with a removable nylon control arm.  For linear actuation, use with a wire linkage (not included).  Includes threaded standoffs for convenient mounting.

    The rotating control arm has locator holes at pre-set distances which accept a wire linkage.  The locator holes allow the arm's effective length to be easily adjusted.  (Note that effective lengh also effects the resulting applied force.  See the force table for details.) 

    The smart actuator is available in larger sizes for increased torque.  How much force can the ACT10 deliver?  It all depends on the effective length of the control arm as shown in the table below.  When using a wire linkage, you can obtain more force by simply adjusting the linkage to a closer locater hole in the control arm, thereby shortening the effective length.

    Given the table values above, you can see that an effective arm length of 1 cm yields a max. force of  0.8kg (1.8lb).  Adjusting the linkage for a longer effective length yields a lower maximum force, while adjusting for a shorter length translates to a higher maximum force.

    You might be wondering how much arm travel the actuator can produce.  For rotary applications, the arm can rotate up to 180 degrees.  For linear applications, the maximum distance will depend on the effective length of the control arm as described previously.  The following table defines maximum linear arm travel distances for several effective arm lengths.  These linear distances define how much linear travel distance can be produced by the actuator when using a wire linkage.

    (Travel distances based on max. arm rotation of 180 degrees.)


    As shown in the table, an effective arm length of 1cm produces a linear travel distance of over 6 cm when rotated 180 degrees and using a linkage.




    Electronic Controller

    Actuators requires a special pulse width modulated (PWM) control signal to operate.  The system includes a digital electronic controller that automatically generates these signals.  Measuring only 2.5" x 3.75", the controller accepts an activation trigger that commands the actuator to a pre-determined rotational position.

    The controller can be customized to accept just about any trigger input signal that you may desire including the following:

    • TTL (0 to 5vdc)
    • Pushbutton / toggle switch
    • RF wireless remote (keyfob, etc.)
    • etc.

    The servo actuator includes our stock controller or a customized controller to meet your requirements.

    Our stock controller accepts a standard switch input.  When switch contacts are closed, the actuator rotates 90/180 degrees.  When deactivated, the actuator returns to the starting point.  Here is a summary of controller features:
    • Customizable for any application
    • Small size (measures 2.5" x 3.75")
    For those with specific needs, we can customize the controller to suit your requirements.




    Wireless RF Option

    We also offer a controller option with wireless remote control.  The wireless system features actuator, keyfob transmitter, and electronic controller with embedded RF receiver.
