ng-TDH, highly productive, Industry 4.0 suitable hand-held micro-sensor screw system with screw system communicator, ng-TDC. Maximum precision of torque/rotational angle measurement with DMS-based, non-contact, rotative torque sensor, directly integrated in bit holder (torque measuring accuracy ±0.5% of the total area). 24-bit digitisation of the torque measuring signal on the sensor rotor. Contact-free, digital signal transmission from the sensor rotor to the housing. 0.1 degree angle resolution, measured at bit holder. Precision brushless DC servo drive with planetary gear, integrated control, adaptive screw strategies, hand button for start/anti-clockwise rotation and sensor LED.
