The MICROMAT-F and MINIMAT-F is a handheld screwdriver that offers both multi-function control as well as a variety of safety features to accommodate worry free use. The press of the units' trigger enables the supply of air to the unit via the newly designed fc20 function control and pneumatic control. Once the unit reaches its preset torque value, the unit shuts off as a result of the sensitive shut-off clutch switch. Additionally, a sensor integrated into the unit's multi function control that determines the correct screw assembly sequence. The screw tightening time is measured and compared a to a predetermined minimum/maximum time frame. If the time falls outside of the pre-set parameters, the user receives an error message. Outboard sensors determine whether or not the screwdriver is enabled.
