Wireless Pokayoke (error-proofing) torque screwdriver RTDFH120CN

When data is received as normal, the answerback function
results in the blue LED indicator glowing.

When data is received as abnormal, the answerback function
results in the red LED indicator glowing.

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 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.

◆ 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.
