Miniaturized 6-axis F/T sensors

Resense 6-axis force torque sensors measure forces and torques in the 3 spatial directions (6 degrees of freedom) using resistive measurement elements. The main advantages are their compact size (up to Ø 8 mm) and the hollow shaft option, which are enabled by the sensor's multi-part deformation body.


The 6-axis F/T sensor kit includes the F/T sensor, the electronics box and an application software to display and record the measurement values.

WITTENSTEIN and WIKA set up joint venture

WITTENSTEIN, the mechatronics corporation, and measuring equipment specialist WIKA Alexander Wiegand SE & Co. KG have set up a joint venture to develop, manufacture and market miniaturized 6-axis force /torque sensors for the industrial market starting from April 1, 2023. 

The two partners will each hold 50% of the shares in Resense, which has its headquarters in Klingenberg am Main (home of WIKA).
