Pokayoke Torque Wrench


Click Type Torque Wrench / Assembly
RoHS marking



Limit Switch

Pokayoke torque wrench with limit switch output to eliminate missed tightening.


  • Pokayoke (tightening assurance).


  • 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 the 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.
  • CSPLS 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.
  • Except for some products, the QSPLS/CSPLS/QRSPLS/SPLS/SPLS-MH/RSPLS/RSPLS-MH/SPLS-N series are 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.


  • SPLS-MH, RSPLS-MH, and SPLS-N-MH are manufactured after your order is received.

  • Except for SPMS2N, products are compliant with ISO 6789:2017 starting January 2022. Calibration Certificates will be different from older products.
