Error-proofing (Pokayoke) Torque Screwdriver
When the set torque is reached, the rotary slip clutch is activated. At the same time, a signal that it has been fully tightened is transmitted by radio. The LED "feedback" system lights up in the handle blue for OK, red for NG (Not Good).
An R-CM receiver (successor to the R-FH256) can recognise the IDs of up to four torque tools. However, simultaneous transmissions are not supported. By using it, a "Poka Yoke" error prevention system can be easily implemented.
NEW: Upgraded products placed on the market in March 2024. Wireless communication range is from 20 to 30 meters (approximate), when in new communication mode. Battery life has significantly improved, from 300,000 to 550,000 shots. Can monitor transmitter battery voltage. Alerts when voltage drops below set voltage (only when operated in new communication mode). Maintenance alert function has been added. When the number you have set is reached, it alerts you it is time for a periodic calibration, etc. (information status March 2024)
Using the optional SB-FH2 setting box and setting software, communication settings for R-CM can be easily executed (wireless). The R-CM receiver can control the number of tightening operations of a torque spanner or torque screwdriver.
NEW: Use of an R-CM receiver or SB-FH2 wireless setting controller lets you switch to older communication mode. Even the R-FH256MC receiver, which was formerly used with the FH256MC transmitter, can receive signals. The recent upgrade lets you use the transmitter switch to check communication mode and switch between old and new modes. (information status March 2024)
The RTDFH wireless screwdrivers comply with the telecommunication standards in Japan, USA, Canada, Thailand, Taiwan, Mexico, Vietnam, China, EU, South Korea, India and Singapore. (information status March 2024)
