Rotary Slip Torque Driver with Limit Switch

Auxiliary

Adjustable types / Preset types

Rotary Slip

Graduation/Preset

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.
