Tohnichi RTDLS / RNTDLS Rotary Slip Torque Driver with Limit Switch

Capacity 120 / 260 / 500 cNm

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.

 

Versions 

 

  • 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.

 

Features

 

  • Rotary slip prevents over-torque
  • Accuracy acc. to EN ISO 6789 (Type II)
  • Curl cord can be extended to approx. 2m in full extension
  • Limit switch specification is AC/DC 30V below 1A
  • 1/4“ female hex insert for standard bits according to DIN 3126 E 6.3 / ISO 1173
  • RTDLS series with traceable calibration certificate (ISO, JCSS) incl.

 

Options / Accs / Spares
