Sensor device, particularly hand tools sensor device

The invention relates to a sensor device, in particular powered hand tools sensor device for detecting an uncontrolled blocking case in a handheld power tool (10), with at least one sensor unit (12) is provided for detecting at least one movement characteristic value (14) of the power tool (10), and with a protective unit (16) which is provided to a control of the hand tool (10) as a function of at least one triggering threshold (18) and the at least one motion characteristic value (14). It is proposed that the protective unit (16) is adapted to determine set at least one triggering threshold (18) variable and / or at least one additional triggering threshold (20).
