ZEMO AT (QIS) System Impulse Wrench

Transducerized Smart Impulse Tool with Angle Control

ZEMO's AT series of EC impulse wrenches have been introduced to the public as world-first innovation at the MOTEK 2010 and experienced a very positive feedback from professional visitors and experts.

The integrated Angle Sensor enables the angle controlled tightening based on the direct measurement of the factor angle. The integrated torque sensor enables the torque controlled tightening based on the direct measurement of the factor torque.

The number of impulses is the third directly measured factor and can be valuated as parameter-value within the tightening curve, or can be used for the impulse no. controlled tightening.

Key Features

• Controlled Torque/Angle-tightening for security-related screw connections in compliance with the VDI/VDE Guideline 2862, Category A.
• Direct measured factors: Torque, Angle, Number of Impulses.
• Additionally integrated O.K./N.O.K.-Status-LEDs in the center of the tool.
• Automatic tool identification and parameter-setting of the Controller.
• Reaction free, thus reducing the RSI-risk and gaining user-acceptance.
• Pistol-style for one-hand-operating (AT-60 to AT-150 only).
• Reducing production time and simultaniously producing the best clamping-force repeatability results.
• Leading to high quality screw connections.
• Equipped with the patented Yokota Twin Blade Impulse Mechanism.
• Double chamber air motor for high-speed tightening and best torque performance.
• No lube air motor to protect the environment.
• Extended oil-change intervals.
• Lightweight.
• Low air consumption, high efficiency air motor.
• High durability, due to improved air motor design features, with special patented air motor vanes.
• Improved ergonomic design for better handling and accessibility.
• Low noise and vibration levels.
• Low trigger force.
