Mountz 170251 (BLRTSX100i-A) - Brushless Rotary Angle Transducer

The Mountz brushless rotary torque & angle sensors an ideal torque-measuring solution for applications where accuracy and reliability rank paramount. Can be used for testing real-time torque or for checking the breakaway torque (first movement) of a fastener.

  • Non-contact signal transfer and maintenance-free.
  • Angle Output: 2-channel quadrature, 360 pulses per rotation.
  • Ability to measure the rotation angle of a fastener. Joint rate & breakaway torque can be measured too.
  • The common brush bounce that plagues the accuracy testing of pulse tools is cured when using a brushless rotary transducer.
  • Compact design & bi-directional.
  • For use with most power tools, high RPM tools, or rotational measurement applications.
  • Features ARCII technology, an instant auto-recognition system of the BLRTSX-A connected to the PTT or LTT.
