Error-proofing (PokaYoke) torque screwdriver with limit switch output to eliminate missed tightening. Ideal for assembly processes with torque monitoring. After reaching the set torque, the limit switch transmits a trigger signal. This can be picked up by means of a PLC, for example. At the same time, the slip clutch is activated, making over-torque impossible. Series RTDLS are adjustable models. Along the micrometer scale, the desired torque can be easily and quickly adjusted. A locking mechanism prevents unintentional torque adjustment during use. Series RNTDLS are fixed models without scale and are particularly suitable for repetitive tightening operations at the same torque. An additional auxiliary tool (sold separately) is available for each of the 500 cNm models for easier power transmission. For counting tightening operations, the LS screwdriver can be connected to an optional 'CNA-4mk3', for example. [...]

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. 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. 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. The RTDFH / RNTDFH wireless screwdrivers comply with the telecommunication standards in Japan, the USA, Malaysia, Thailand, Taiwan, Mexico, Vietnam, China, the EU, South Korea, Russia and India (information status June 2021).

Colour Marking Preset Clicker Torque Driver A world first! When the set torque is achieved, it automatically marks evidence of proper tightening on the heads of small screws and bolts. It determines whether tightening has been missed by detecting the presence or absence of marks, at the end of the manufacturing process and after shipping. MNTD series Error-proofing (Pokayoke) torque drivers mark small screws and bolts after tightening, as a human tightening error countermeasure. It is common to use a pen to mark work after tightening with a torque screwdriver, but with a Tohnichi marking tool the two actions are combined into one, improving productivity. When set torque is achieved, marking is done automatically, eliminating the possibility of an operator otherwise forgetting to mark work. Clearly identifiable marks provide evidence of tightening to the required torque, and this evidence remains even after manufacturing and shipping. [...]

Click-Type Screwdriver for Assembly. Tohnichi NTD torque screwdrivers are used for repetitive tightening to a preset torque in mass production and maintenance. The preset design is ideal for use with fixed torque values in production lines. Commercially available standard 1/4 inch hex bits can be used (E 6.3). Like RNTD but with a click signal instead of the slip clutch. Ideal for applications that are sensitive to vibration and where rotary clutch vibrations might be problematic. Key Features: Accuracy acc. EN ISO 6789 type II class C Clockwise rotation Click signal Standard bit insert E 6.3 (1/4 inch) Scope of Supply: Torque Screwdriver NTD Resin grip for model 120CN and 260CN NTD500CN and NTD1000CN come with an auxiliary T-handle Original operating instructions (jap./eng.)
