Tohnichi RTDLS

Capacity 120 / 260 / 500 cNm

Rotary Slip Torque Driver with Limit Switch

Error-proofing (Pokayoke) torque driver with limit switch output to eliminate missed tightening. Ideal for torque verification assembly processes. The toggle is activated when set torque is achieved. Rotary slip occurs simultaneously with output of a contact signal from the limit switch.

Establish interlock system at assembly line by connecting the signals from limit switch to external devices such as PLC (Programmable logic controller). Limit switch can alternatively be connected to CNA-4mk3 to create tightening count management system.

Tohnichi has changed the locker design from old circled shape to the new hexagonal shape and this could prevent the torque screwdriver from rolling and unexpected dropping. Lockers are important parts that maintain alignment of readings.

RTDLS models are adjustable type with torque scale. LS wrenches are supplied with a durable curl cord. Compliant with calibration procedures of ISO 6789 Type II Class D.

 

Features

  • Rotary slip prevents over-torque.
  • Easy torque adjustment with scale.
  • Accuracy acc. to DIN EN ISO 6789 (Type II, Class D).
  • 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.
  • Traceable calibration certificate (ISO/JCSS).

 

Options

  • Female connector for LS cable is sold separately (WA5219K).
  • English scale (lbf·in) available on request.
  • Auxiliary tightening tool for model 500 cNm can be attached (sold separately).

* The requirements and testing methods of the DIN EN ISO 6789 are valid for the rated output (capacity) for a measuring range from 20% to 100%.

A torque tool should be selected so that it is mainly used in its medium torque range. If you had to work regularly close to the maximum load capacity, a larger model should be chosen to prevent risk of overtorquing.
