Equipped with a brushless motor. Tightening torque accuracy: ±5% Electric Unitork with torque scale. Easy to establish a Pokayoke (error-proof) system for managing the number of tightening operations.
Left: DU250CN Right: DU-COUNTER
Application
For plastic screws and tapping screws.
Features
The torque scale makes tightening management easier and ensures better traceability.
Electric type; reduces maintenance costs and facilitates installation.
Use the same tool for provisional tightening and final tightening. Tightening accuracy: ±5%
The LED light and buzzer built into the DU body make it easy to tell when tightening-to-completion is achieved.
Comes with forward/reverse capability. (Torque control: Clockwise only)
DU-COUNTER makes it possible to set the number of tightenings, using a count-down display: 10 -> 9 -> 8, etc.
To make a pass/fail judgment, you can set the DU-COUNTER to preset judgment, which is made when tightening count reaches “00", or you can set it to automatic judgment with the Set Time feature.
The DU-COUNTER comes with a feature to prevent double counts. After the tightened-to-completion signal is received, you can set time until the next signal input, to prevent a mistaken count.
You can switch DU-COUNTER rotational speed to either “High" or “Low".
Select from a wide range of power sources for the DU-COUNTER, from AC 100V to AC 240V.
