Task

The haptic behavior of rotary switches should be measured based on torque/rotation angle. The exact determination of the torque to be applied is an important control variable for a rotary switch in terms of haptic behavior (adjustment force to be applied > proprioceptive perception > tactile perception).  

Specific Requirement

Very low nominal torque due to low operating forces. Fine angle resolution to map the fine detent points of the rotary switch. 

Solution

The Type 8661 torque sensor measures even the smallest torques over a defined angle range in forward and reverse rotation with high precision and reproducibility. Using the Type 8661 torque sensor also reduces the design complexity, as no additional angle sensor is required.
The haptic behavior of the rotary switches is evaluated with the DIGIFORCE® 9307 based on the torque/rotation angle curve.
