Electric System Wrenches
Battery system wrench YS-e wrench
High tightening functions like torque control, angle monitoring etc., inherited from Yokota air operated system wrenches, are realized even by battery operated ones..
- Working efficiency improvement by wireless technology
- Simplification of installation and relocation
- Clean & Silent
- Low vibration and Low reaction force
Workability Improvement by such design as compact, light-weight and more quiet
No need of power cord (air hose or power supply cord) and signal cable owing to the battery operation and
wireless communication. Simplification of installation and relocation owing to the saving of wiring harness
System configuration
• Possible to connect 4 tools with the wireless unit
• WLAN communication between tool and controller
• Poka Yoke compatible
• Traceability tightening data
• LAN and RS 232 interface
• I/O terminal for input and output signals
Features YS-e
- Strain gauge and direct current detection system make the tool compact and weight saving
- Low vibration, low noise and low reaction force due to the direct drive
- Built-in controller and driver functions
- Built-in buzzer/LED inform an operator of tightening result and abnormal tightening
- Battery with remaining capacity display adopted.
- Tool Protector with different color by model
- Applicable capacity : Line-up to M5-M10 (5-50Nm)

Air System Wrenches Torque control and Angle monitoring
High accuracy
Product liability is essential to car manufacture. All tightened joints have to be correct. For this reason critical joints must be counted, documented and, of course, tightened with the right clamping force. In order to do this, you need an impulse wrench (with a built-in transducer) connected to a controller. This system ensures that only OK joints are counted resulting in "Zero Fault Production". This fail-safe system fits perfectly in the Poka Yoke Strategy.
