The screwdriver with a controlled clutch-function
  • thread forming with maximum motor power
  • seating torque less than driving torque
  • thread forming instead of thread damaging
  • ergonomic
  • robust

The handheld pneumatic screwdriver 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 especially designed for applications where the driving torque (thread-forming force) is close to – or even higher – than the seating torque, due to the occurring high friction during assembly. It is possible to equip this screwdriver with a mechanical clutch-lock-out, which allows the safe assembly of thread forming-, thread cutting-or self-tapping screws. This clutch-lock-out eliminates a damaging over-tightening of the screw.

The SENSOMAT screwdriver assembles the screw with full motor power. Shortly before the screw is seated,  the driver releases the clutch and the screwdriver shuts off at the pre-set torque. The screw is therefore fully assembled, without being stripped or otherwise damaged.

The SENSOMAT, a further development of the MINIMAT screwdriver series, incorporates a highly accurate shut-off clutch that reachesa high torque-accuracy of less than ≤3 % standard deviation. DEPRAG pneumatic screwdrivers with a shut-off clutch operated at suitable surrounding conditions achieve a Cmk value of ≥1.67 with a tolerance requirement of 15 % in relation to 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.
