Locking Bit Selection Unit for Error-Proof Tightening
Ensure correct bit selection and stable program matching with a locking mechanism, preventing errors and improving reliability in tightening operations.

Secure and Reliable Bit Selection for Accurate Tightening
The KR004-SJ Locking Bit Selection Unit is designed to ensure correct bit selection and stable identification during tightening operations.
With its locking mechanism, it prevents incorrect insertion or misalignment, ensuring that each fastening task is executed with the correct program and parameters.
Key Capabilities
Locking Mechanism for Stability
Securely lock the selected bit in position, preventing movement or misalignment during operation.
Error-Proof Bit Selection
Ensure that only the correct bit is used, reducing the risk of incorrect torque or fastening errors.
Reliable Program Matching
Work with the control system to automatically activate the correct tightening program based on the selected bit.
Enhanced Operational Safety
Reduce accidental misuse and improve process safety through controlled and stable selection.
Why Locking Matters in Bit Selection
Without Locking Mechanism
- Bits may be incorrectly inserted or loosely positioned
- Higher risk of misidentification and incorrect program activation
- Increased possibility of fastening errors
- Reduced process reliability
With KR004-SJ Locking System
- Bit is securely fixed in the correct position
- Stable and accurate identification every time
- Reduced risk of incorrect torque application
- Improved reliability in critical operations
FAQ
What is the purpose of the locking bit selection unit?
The locking bit selection unit ensures correct bit selection and stable positioning during tightening operations. It prevents misalignment and guarantees that the correct tightening program is activated for each task.
What is the advantage of the locking mechanism?
The locking mechanism secures the bit firmly in position, preventing movement or incorrect insertion. This improves identification accuracy and ensures reliable program matching during operation.
How does it prevent tightening errors?
By ensuring that the correct bit is securely positioned and properly identified, the system activates the corresponding tightening program, reducing the risk of incorrect torque application.
How is it different from a standard tool selection unit?
A standard selection unit identifies the selected bit or socket, while the locking version adds a physical locking mechanism to ensure stability and prevent misplacement, offering higher reliability in critical applications.
Does it automatically switch tightening programs?
Yes. Once the bit is locked in position, the system sends a signal to the controller, which automatically activates the corresponding tightening program.
Can it be integrated with existing tightening systems?
Yes. It works with KR002-B01 field controllers and can be integrated into systems managed by KR002-H01 supervisory controllers.
Is it suitable for high-precision or critical applications?
Yes. It is specifically designed for applications where accuracy, stability, and error prevention are critical, such as high-value or precision assembly processes.
Does it require operator training?
No. The system is designed to be intuitive. The locking mechanism and structured selection process make it easy for operators to use with minimal training.
