The demand for collaborative robots is growing fast, but these robots or Cobots must also work safely alongside humans. TE Connectivity (TE) has a solution to provide functional safety in the next generation of human-robot collaboration with increased accuracy and speed. TE’s ring-shaped safety torque sensors are designed to be integrated at each Cobot joint, meeting the new level of safety requirements up to ISO13849 Category 3 PL d. Optimized for collaborative robots the sensor provides low susceptibility to crosstalk allowing increased accuracy. With available customized mechanical interfaces the sensor can be easily adapted to meet specific customer application requirements. With a standard I2C digital interface the sensor allows easy integration. The safety torque sensor incorporates proven Microfused sensing technology with excellent long-term span and zero stability.
