The air-operated stationary screwdrivers SENSOMAT with a mechanical clutch-function is especially well suited for applications, such as

• sheet-metal assemblies
• wood assemblies
• self-drilling pass-through screws

The SENSOMAT was designed for screw assemblies where the driving-torque (thread-forming force) is close to - or even higher - than the seating torque. It is possible to equip this Screwdriver with a mechanical clutch-lock-out, which allows the safe assembly of thread forming- or thread cutting screws. A damaging over-tightening of the screw is impossible.

The SENSOMAT drives the screw with full motor power. Shortly before the screw bottoms out, the shut-off clutch is activated and the driver shuts-off exactly at the preset torque. The screw is completely seated without any damage to the screw-thread.

The SENSOMAT, a further development of the MINIMAT screwdriver series, incorporates a highly accurate shut-off clutch that reaches a high torque-accuracy of less than ± 3% standard deviation. DEPRAG air-operated Screwdrivers with a shut-off clutch operated at suitable surrounding conditions a Cmk value of ≥ 1.67 at a +/-10% tolerance based on 6 Sigma according to ISO 5393. A Cmk value of 1.67 means that there is a failure rate of only 0.6 per one million screw assemblies.
