Overview

Custom torque sensor for intergrated and improved functional safety in collaborative robots.
Safety Torque Sensor

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 4 PL e. 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.
