Made in Japan
Manufacturer: Tohnichi
Model: T-BLA/QLBLA

Now also available in the U.S., Canada, and Mexico. Torque wrench with wireless “pokayoke” error proofing to prevent missed tightening, using the Energy Harvest system for solar power generation. No need to change batteries, eliminating battery expense and bothersome battery replacements. The R-BL receiver has been upgraded to the R-CM, which is downward compatible.

Application

• Pokayoke error-proof system helps prevent human error when tightening bolts and screws
• Assembly line interlock control system using tightening count control
• Pokayoke (error-proof) system / Tightening control system

Features

• Conforms with technical standards of the U.S. and Canada.
• A world first! Uses the “Energy Harvest” solar power generation system.
• No need to change batteries, reducing cost and time, and no dead batteries to dispose of. Result: A more eco-friendly torque wrench.
• Doesn’t require much light for regular use! Under normal interior illumination in an ordinary factory and powered only by a solar panel, the device can transmit tightened-to-completion signals for a Pokayoke (error-proofing) system.
• Easy set up. When you hear the “Click!” the transmitter/receiver setting is done. Just operate the torque wrench to set the transmitter/receiver setting. * For the R-BLA, place the unit in Set Mode, then operate the torque wrench.
• Many Tohnichi LS-type torque wrenches that are currently in use can be converted into battery-less, wireless Pokayoke torque wrenches. The limit switch component on 278 models of Tohnichi’s wired LS-type torque wrenches can be converted by customers on their own, to upgrade their existing models at a low cost. 156 models in Tohnichi’s lineup of 278 LS-type torque wrenches can be shipped with the T-BL transmitter mounted. For further details, refer to the catalog.
• The T-BLA/QLBLA is for use only in the U.S., Canada and Mexico. The T-BLE/QLBLE model is available for use in the EU and China. The T-BL/QLBL is for use only in Japan.
• The QLBLA series is compliant with ISO 6789:2017 starting January 2022. For more information, see the technical data “Initiatives for ISO 6789:2017” at the bottom of the screen.

Specifications

Note:

Note 1: This product can be used in the U.S., Canada, Mexico and Colombia.

Note 2: Effective distance between transmitter and receiver depends on radio wave environment. In some cases it may be shorter than expected.

* Note: Causes of transmission errors include: ambient noise; an obstacle between the transmitter and the receiver; dead points caused by signal reflection from metal, concrete, or other material that prevents direct transmission to the receiver antenna.

Note 3: Solar cells power the transmitter, so the equipment should be used in lighting conditions exceeding 200lx.

* If starting with a battery at zero charge, under lighting of 200lx about 3 minutes are required before first transmission.

* At full battery charge, under completely dark conditions (0lx), signals would still be emitted for more than 1,800 tightening operations.

* After full battery charge is reached, if the unit is stored in complete darkness (0lx), the charge would be depleted after about 6 days.

* Even while the torque wrench is in operation, the solar cells will still charge the unit under lighting of at least 200lx, so there is no need to charge fully before use.

*SI unit products and metric unit products in the QLBLA series are compliant with ISO 6789:2017 starting January 2022. Calibration Certificates will be different from older products. American unit products are not compliant with ISO 6789:2017.
