Economical positioning system for low power applications

Special features

  • Space-saving, compact design
  • Separated supply voltages for control and performance electronics
  • Extremely accurate positioning due to measurement of the position at the output side
  • Bus interfaces simplify start-up and wiring complexity

The PSE 21x-8 positioning system is a compact solutions with integrated intelligence that frees up the machine´s central control unit. The intelligent positioning system automatically adjusts auxiliary and positioning axes using a DC-motor, gear, controller, measuring system and CANopen, DeviceNet or Modbus RTU interface. No external motors, proximity or limit switches are required. 

The absolute measuring system at 64 revolutions (optional) eliminates the need for time-consuming reference runs and increases the efficiency of the machine.
The economical motor also makes the system suitable for automation jobs that were previously uneconomic due to the cost. The separated supply voltages for the control and performance electronics provides an emergency shut-off function without interrupting communication with the control module.

Address and baud rate switches (optional) simplify start-up, even without the knowledge of the control software. If necessary, the instruments can be mounted on a spindle using the hollow shaft without the need for an additional coupling. The ability to move the connecting cable to various positions (turnable in steps of 90°) is a special feature of the PSE 21x-8, allowing users to respond flexibly to individual installation situations.


  • Address may be set using the bus or an address switch, baud rate set via switch (optional).
  • Mounting via solid shaft or hollow shaft.
  • Position of the connecting cable can be adjusted according to the installation situation.
