TTES / TTAS Series Wireless Rotary Torque Transducer (Square Drive)

(Also known as Wireless Rotary Torque Sensor – Square Drive Type / Non-Contact Torque Transmitter for Impact & Pulse Tools)

A TTES / TTAS Series Wireless Rotary Torque Transducer (Square Drive) is a non-contact, high-speed torque sensor designed to measure and transmit real-time torque and angle data from rotating power tools that use square-drive sockets (such as impact wrenches, pulse tools, or torque multipliers). It replaces traditional wired or slip-ring sensors with a wireless data transmission system, enabling accurate torque measurement under dynamic, high-vibration, and high-RPM conditions — ideal for industrial bolting, assembly, and quality verification applications. This transducer type is designed for use in pneumatic, hydraulic, or electric torque tools.
