FUTEK has announced the QTA141 Micro Reaction Torque Sensor. With a miniature footprint of 22 mm in diameter by 10 mm in height, the sensor was designed to provide a precision torque measurement solution for miniature DC servo motors. It also features a 10 mm diameter central hole, allowing a motor drive shaft and coupling to pass cleanly through the sensor. The reduction in size allows the product to fit where most reaction torque sensors cannot.

The sensor features ±0.5% non-linearity, ±0.5% hysteresis and ±0.1% non-repeatability, with metal foil strain gauges in both clockwise and counter-clockwise torque directions. Other features include: a 1 Nm capacity that is said to exceed the stall torque of other 22 mm gear motors; rated output of 1.3 mV/V; safe overload of 150%; and lightweight aluminium construction.
