The QTA163 Rotary Torque Sensor is a state-of-the-art, miniature rotary torque sensor designed for space-limited applications where traditional torque measurements have been challenging. With its compact dimensions—0.7 inches by 0.7 inches (17mm x 17mm) cross-section and a length of 2.01 inches (53mm)—the QTA163 is the smallest rotary torque sensor in FUTEK's catalog, offering exceptional performance in space-constrained environments. It features a 5mm male shaft-to-shaft with flats, capable of accurately measuring torque up to 2 Nm in rotational systems operating at speeds up to 150 RPM.

Engineered for precision, the QTA163 boasts impressive performance specifications, including a nonlinearity of ± 0.1% of rated output, hysteresis of ± 0.2% of rated output, and nonrepeatability of ± 0.05% of rated output. These specifications ensure highly reliable and accurate torque measurements, even in demanding applications. The sensor also includes a custom-built slip ring that facilitates precise signal transfer from the rotating shaft to the stationary stator, supported by high-precision machining.

With its robust construction—featuring a 17-4PH stainless steel shaft with flats and aluminum housing, and compliance with RoHS standards—the QTA163 is an indispensable solution for engineers seeking precise and reliable torque measurements in compact, space-limited environments.
