Long-term stable positioning without permanent power supply

Once displaced, actuators with PIRest technology hold their position stable without permanent control voltage. Nanometer precision, maintenance-friendly and inexpensive adjustments are possible even at inaccessible locations.

High user-friendliness due to automatic configuration

Important operating parameters are stored on the mechanic's ID chip and are read out automatically when the electronics are switched on.
