About Error-proofing (Pokayoke) Torque Driver RTDFH / RNTDFH

Error-proofing (Pokayoke) Torque Driver RTDFH / RNTDFH

Application

Pokayoke (tightening error-proof)

Features

When set torque is achieved the toggle activates, and at the same time a wireless tightened-to-completion signal is transmitted.
Cordless to greatly improve workability.
The Receiver R-FH256 has proven effectiveness for use with the wireless Pokayoke (error-proofing) FH-256MC torque wrench. A system combining use of a wireless Pokayoke (error-proofing) torque wrench and a wireless Pokayoke torque screwdriver can be built at low cost.
Uses answerback system for operator to verify communication status.
The IDs of four torque screwdrivers can be verified by one receiver (when using the I/O-FH256 multi-box). This makes it easy to establish an error-proof system with the count checker CNA-4mk3.
Frequency hopping system enhances transmission reliability.
The RTDFH / RNTDFH conform to telecommunication standards in Japan, the U.S., Canada, Malaysia, Indonesia, Thailand, Taiwan, Mexico, Vietnam, China, the EU, South Korea and Russia (information valid as of March 2019). For other countries and regions, please contact Tohnichi.

Pokayoke Error-Proofing Technology

Pokayoke technology within the RTDFH/RNTDFH torque driver actively prevents errors in fastening, ensuring correct torque application every cycle. The combination of tactile and audible feedback signals completion, minimizing faulty assemblies. This feature is ideal for precision environments like electronics and automotive assembly, where reliability is paramount.

Ergonomic Design and Durable Build

Crafted with stainless steel and alloy steel, the torque driver promises durability and resistance against wear. The soft TPE handle enhances grip comfort, reducing fatigue over extended use. With dimensions tailored to hand fit and a chrome-plated finish, operators enjoy both safety and lasting quality throughout daily operations.

Integrated Torque Gauge for Accuracy

Each model incorporates an integrated torque gauge that allows users to monitor torque levels in real time. The driver limits torque to pre-set values, preventing over-tightening or under-tightening. This ensures consistent results and upholds product qualitykey for stringent assembly and quality control processes.

FAQs of Error-proofing (Pokayoke) Torque Driver RTDFH / RNTDFH:

Q: How does the Pokayoke error-proofing function in the RTDFH/RNTDFH Series torque driver?
