Welcome to the Dr. Siebert Industrial Representation
Established in 1990 and located in Stahnsdorf, Germany, Dr. Siebert Industrial Representation is an experienced distributor of drive and automation control components for the standard industrial and individual requirements.
The most important products we sell are stepper motors, controllers, and power end levels for stepper motors, manufactured by the PHYTRON-Elektronik GmbH (Germany).
The fields of application of the motors made by PHYTRON are, for example, food and packaging, paper and print industry, or handling and positioning. We also offer special motors for use under extreme conditions like vacuum, space, clean and extreme environment or low temperatures. 
PHYTRON products suite perfectly special requirements of medical engineering, aeronautical engineering, nuclear research, and other advanced applications.
To control a motor you may need a motor drive, controller or power stage. We can help you make the proper choice among multiple control devices according to such application criteria as construction characteristics, motor power, step resolution, number of axis, interface, etc.
Various handling and positioning tasks can be performed equally well under special operating conditions.
For handling tasks we also offer the complete solutions, such as one or more axis positioning systems for linear movements and/or rotation movements, equipped with suitable drives. Individual solutions for operation under special conditions are also possible.
Aside from the stepper motors we offer servo actuators from MATTKE AG (Germany).
We can quickly deliver various small motors and automation control components of the French manufacturer CROUZET, such as
the logic controller Millenium 3 with its numerous application possibilities. With the Millenium 3, devices and sequences with 10 to 50 inputs and outputs can be automated (see “Application examples”).
For some specific application fields (e.g. "Solar tracking"), custom programmed modules are available.
Another product line is represented by micro switches and position switches manufactured by CROUZET. Special solutions for complicated application conditions are also possible. To guarantee perfect integration in all types of devices, CROUZET offers the possibility to adapt the switches and sensors to the respective customer wishes.
We offer free technical consulting service to help you make the optimum choice of electric drives and automation assemblies.
