HERUTU Pokayoke Tools – Mistake-Proofing & Traceability Solutions
HERUTU Electronics Corporation’s Pokayoke tools are industrial wireless solutions designed to help manufacturers implement effective mistake-proofing (Poka-yoke) in assembly and production processes. These tools support quality control, error prevention, task traceability, and process synchronization by enabling wireless communication between work tools and control systems.
Pokayoke, meaning “mistake-proofing,” is a core concept in lean manufacturing that helps prevent human errors and ensures that each process step is completed correctly the first time


Pokayoke Transmitters & Receivers
(TW-800 / TW-850 / TW-810 / TW-820 Series)
HERUTU’s Pokayoke transmitters attach to existing tools such as torque wrenches, pliers wrenches, electric screwdrivers, and other handheld devices. When a task is completed or a defined condition is met, the transmitter sends a wireless signal to a Pokayoke receiver.
This enables immediate detection of correct or incorrect operations, supporting automatic quality checks and preventing process omissions.
Available transmitter variants include standard, compact, and slim types to suit different tools, space constraints, and battery life requirements. Pokayoke receivers provide outputs suitable for system integration, including relay, LAN, RS-232C, and fieldbus interfaces, allowing easy connection with PLCs and production control systems.


Check Pen S – Pokayoke Marking Verification
The Check Pen S is a wireless marking pen designed to prevent omission of marking operations on production lines. It communicates wirelessly with Pokayoke receivers to confirm that each required marking step has been performed.
Compatible with a wide range of commercially available pens and self-inking stamps, the Check Pen S improves error detection in marking processes and ensures traceability of completed work.




Pokayoke - Compatible Pliers Wrench
HERUTU’s Pokayoke-compatible pliers wrenches integrate wireless transmitters that send confirmation signals when the correct grasping or release operation is performed. Certain models include false-transmission prevention functions, ensuring signals are only sent during proper operation.
These tools are especially useful in clamping, hose assembly, and similar processes where missed or incorrect operations can impact product quality.
Production Process Support – Software & System Integration
HERUTU provides software and system integration tools that work together with Pokayoke receivers to collect task data, display real-time work status, and manage traceability across multiple workstations.
These solutions help visualize production progress, review operation history, and ensure compliance with standard work procedures and quality requirements.
