Features

  • Adjustable style torque wrench with limit switch output.
  • Upon reaching the set torque, the torque wrench "clicks" to complete tightening while the limit switch simultaneously sends out a contact signal.
  • A limit switch can be connected to a CNA-4mk3 count checker (sold separately) to easily create a tightening count management system.
  • Signals from a limit switch are captured on a programmable logic controller (PLC) or similar device to establish a Tightening Assurance System using assembly line interlock controls.
  • LS wrenches are supplied with a durable curl cord.
  • QLLS, CLLS and PCLLS series products are interchangeable head torque wrenches. Tohnichi’s interchangeable head lineup offers the best selection in the world, making these wrenches ideal for your work.
