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.

Non-contact proximity switches operate free from wear and guarantee faster response times than mechanical limit sensors.
