your reliable partner EAS®-compact® - the economically viable protection for machines Function If the set limit torque is exceeded, the clutch disengages. The torque drops immediately. A mounted limit switch registers the disengagement movement and switches off the drive. The limit switch signal can also be used for further control functions. After the malfunction has been rectified, the EAS®-compact® ratchetting clutches and the EAS®-compact® synchronous clutches automatically re-engage (for a detailed description of the re-engagement behaviour, see page 5). Overload clutches of the series...
