It is possible with SIKUMAT® Torque Limiters to utilise the axial movement during an overload occurrence to actuate a proximity switch so that when the preset limit torque is exceeded, the drive can be switched off electrically and/or a signal can be triggered.

Switching off the drive in case of overload is essential for all ratcheting type SIKUMAT® Torque Limiters in order to prevent ratcheting over prolonged periods and possible wear.

The engagement travel of the SIKUMAT® Torque Limiters can be found in the respective tables.

The arm of the proximity switch should be positioned at a distance of 0,1 mm to the contact surface of the torque limiter.
