Power tool

A power tool comprising:

• a frame;
• a tool head rotatably coupled to the frame;
• a piston moveable along an axis to perform a work operation on a workpiece;
• a first sensor in a floating arrangement within a cavity of the tool head;
• a biasing element that biases the first sensor to maintain the first sensor in a predetermined axial position relative to the tool head;
• a second sensor;
• and
• a controller that determines if the work operation was completed by comparing information from the first sensor and the second sensor.

A power tool comprising:

• a frame;
• a tool head rotatably coupled to the frame;
• a piston moveable along an axis to perform a crimp on a workpiece;
• a first sensor that moves relative to the frame to maintain a predetermined axial position relative to the tool head, the first sensor sensing movement of the piston;
• and
• a controller that receives first sensor information from the first sensor and determines a crimp profile based on the first sensor information.
