Limit Switch

Error-proofing (Pokayoke) torque driver with limit switch output to eliminate missed tightening.

RTDLS120CN

RTDLS500CN with an auxiliary tightening tool (sold separately)

Example of a Pokayoke (error-proofing) configuration:

Application

  • Pokayoke (tightening error-proof)

Features

  • Preset style torque wrench with limit switch output.
  • The toggle is activated when set torque is achieved. Rotary slip occurs simultaneously with output of a contact signal from the limit switch.
  • RTDLS models are adjustable type with torque scale. RNTDLS models are preset type, and are especially useful for repeated tightening operations at the same torque.
  • Limit switch can be connected to CNA-4mk3 to create tightening count management system.
  • Establish interlock system at assembly line by connecting the signals from limit switch to external devices such as PLC (Programmable logic controller).
  • LS wrenches are supplied with a durable curl cord.

◆ How to order

Specify Tohnichi, model name and torque value.

[Example 1] Tohnichi RTDLS120CN

[Example 2] Tohnichi RNTDLS120CNX90cN・m

Specify model name and torque value when you order a product in the RNTDLS series.

◆ Things to remember when ordering

Standard bits on the market can be used. (6.35 HEX)

RNTDLS 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.
