Error-proofing (Pokayoke) Torque Driver

RTDFH / RNTDFH

Remote signal rotary slip torque screwdriver

Prevents human tightening errors (Pokayoke)

Rotary Slip

Wireless

Cordless. Prevents missed tightening. The R-FH256 receiver has been upgraded to the R-CM, which is downward compatible.

Wireless Pokayoke (error-proofing) torque screwdriver RTDFH120CN

Wireless Pokayoke (error proofing) Torque Screwdriver RNTDFH500CN

LED “answer-back” system signals Blue for OK, Red for NG (No Good).

Example of a Pokayoke (error-proofing) configuration:

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 R-CM receiver is the successor to the R-FH256, which has successfully partnered with the wireless Pokayoke (error proofing) FH256MC torque wrench. You can build a low cost system that combines use of wireless Pokayoke torque wrenches with wireless Pokayoke torque screwdrivers.
Uses answerback system for operator to verify communication status.
One R-CM receiver can recognize the IDs of up to four torque screwdrivers. Combining their use with the CNA-4mk3 Count Checker makes it easy to build a Pokayoke (error proofing) system.
Frequency hopping system enhances transmission reliability.
The RTDFH/RNTDFH series conforms to telecommunication standards in Japan, the U.S., Malaysia, Thailand, Taiwan, Mexico, Vietnam, China, the EU, South Korea, Russia, and India. (Information valid as of June 2021.) For other countries, please contact Tohnichi.

(RTD/RNTDFHS500CN)

One R-CM receiver can communicate with a maximum of four torque devices, but it does not function with a mixture of new and old telecommunication modes. (You can use the SB-FH2 setting controller to switch FHM and CSPFHW to the older telecommunication mode.)

Standard accessory

Only RTDFH260CN and RTDFH500CN models come with an adjustable open head.

◆ How to order

Specify Tohnichi, model name and torque value.

[Example 1] Tohnichi RTDFH120CN

[Example 2] Tohnichi RNTDFH120CNX90cN・m

When ordering an RNTDFH series product, please specify the Tohnichi model name and torque value.

◆ Things to remember when ordering

Standard bits on the market can be used. (6.35 HEX)

RNTDFH is preset, so you cannot set torque without a tester. If you prefer torque setting prior to delivery, indicate torque value when you place the order. Torque setting before delivery is free of charge.
